Using FusionCharts XT with PHP - Basic Examples

FusionCharts XT can effectively be used with PHP to plot dynamic data-driven charts.

Even when used with PHP, FusionCharts XT internally uses JavaScript and XML/JSON to render the charts. The PHP code actually helps you output this JavaScript and XML/JSON. To aid your understanding of this section, we will recommend you to go through the following sections of documentation (if you've not already read them):

In this section, we will show a few basic examples to help you get started.

We will cover the following examples here:

  1. Using FusionCharts XT in PHP with a pre-built Data.xml (which contains data to plot)
  2. Changing the above chart into a single-page-chart using Data String method
  3. Using HTML Embedding method to render the chart
  4. Creating pure JavaScript charts
  5. Using JSON data to create chart
  6. Creating multiple charts in a single page
  7. Creating transparent chart
  8. Setting managed printing for Mozilla browsers
  9. Creating chart with multiple sets of data
  10. Creating a stacked chart
  11. Creating a combination chart
  12. Creating a combination chart with multiple units

Let's quickly see each of them.

Before you go further with this page, we strictly recommend you to please go through the How FusionCharts XT works? and Creating Your First Chart sections, as we will discuss concepts explained in these sections.

All codes discussed here are present in Download Package > Code > PHP > BasicExample folder.

Setting up the charts for use

In our code, we have used the charts and JavaScript class files contained in Download Package > Code > FusionCharts folder. When you run your samples, you need to make sure that the SWF files are in proper location.
Plotting a chart from data contained in Data.xml

Let's now build our first example. In this example, we will create a "Monthly Unit Sales" chart using the Data URL method. For a start, we will manually code our XML data in a physical XML document Data.xml and then utilize it in our chart contained in a PHP Page (SimpleChart.php). The chart will look like the image shown below:

Let's first have a look at the XML Data document:

 
<chart caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units' showValues='0' formatNumberScale='0' showBorder='1'>
  <set label='Jan' value='462' />
  <set label='Feb' value='857' />
  <set label='Mar' value='671' />
  <set label='Apr' value='494' />
  <set label='May' value='761' />
  <set label='Jun' value='960' />
  <set label='Jul' value='629' />
  <set label='Aug' value='622' />
  <set label='Sep' value='376' />
  <set label='Oct' value='494' />
  <set label='Nov' value='761' />
  <set label='Dec' value='960' />
</chart>

This XML is stored as Data.xml in the Data Folder under BasicExample folder. It basically contains the data to create a single series chart to show "Monthly Unit Sales". We will plot this on a Column 3D Chart. Let's see how to do that.

To plot a chart that consumes this data, you need to include the HTML+ JavaScript code to embed a chart object and then provide the requisite parameters. To make things simpler for you, we have put all this functionality in a PHP function named as renderChart(). This function is contained in Download Package > Code > PHP > Includes > FusionCharts.php file. So, whenever you need to work with FusionCharts XT in PHP, just include this file in your page and then you can work with FusionCharts XT very easily.

Let's see it in example. SimpleChart.php contains the following code to render the chart:

 
<?php
      //We have included ../Includes/FusionCharts.php, which contains functions
      //to help us easily embed the charts.
      include("../Includes/FusionCharts.php");
      ?>
      <HTML>
         <HEAD>      
            <?php
      //You need to include the following JS file, if you intend to embed the chart using JavaScript.
      //When you make your own charts, make sure that the path to this JS file is correct. Else, you
      //will get JavaScript errors.
      ?> 
      <SCRIPT LANGUAGE="Javascript" SRC="../../FusionCharts/FusionCharts.js"></SCRIPT>
      <TITLE>FusionCharts XT - Simple Column 3D Chart</TITLE> 
   </HEAD>
   <BODY>
   <?php
      //Create the chart - Column 3D Chart with data from Data/Data.xml
      echo renderChart("../../FusionCharts/Column3D.swf", "Data/Data.xml", "", "myFirst", 600, 300, false, true); 
   ?>
   </BODY>
</HTML>

As you can see above, we have:

  1. Included FusionCharts.php to help us easily create charts
  2. Added the FusionCharts.js that helps in generating the chart, handles events and provides advanced features like JavaScript fallback, etc.
  3. We have simply invoked the renderChart function to render the chart. To this function, you can pass the following parameters (in same order):
Parameter Description
chartSWF SWF File Name (and Path) of the chart which you intend to plot. Here, we are plotting a Column 3D chart. So, we have specified it as ../../FusionCharts/Column3D.swf
dataUrl If you intend to use the Data URL method for the chart, pass the URL as this parameter. Else, set it to "" (in case of Data String method). In this case, we are using Data.xml file, so we specify Data/Data.xml
dataStr If you intend to use the Data String method for this chart, pass the XML/JSON Data String as this parameter. Else, set it to "" (in case of Data URL method). Since, in this above case, we are using the Data URL method, we specify this parameter as "".
chartId ID for the chart, using which it will be recognized in the HTML page. Each chart on the page needs to have a unique ID.

To provide cross-browser compatibility, we recommend you not to start the ID with a numerical value, nor use space as part of the ID.
chartWidth Intended width for the chart (in pixels or in percent), for example, "400"  or "100%".
chartHeight Intended height for the chart (in pixels or in percent), for example, "400"  or "100%".
debugMode Whether to start the chart in debug mode. Please see the Debugging your Charts section for more details on Debug Mode. The acceptable values are true and false.
registerWithJS Whether to register the chart with JavaScript. This option is deprecated and kept for backward compatibility reasons. The value is always set to true.
allowTransparent (optional) Whether the chart can be set to have a transparent background. This work together with bgAlpha attribute of chart which needs to be set to a value lower than 100.

When you now run this page, you will see a chart like the one below.

If you do not see a chart like the one below, please follow the steps listed in Debugging your Charts > Basic Troubleshooting section of this documentation.

Advanced note : Apart from renderChart()function, FusionCharts.php provides a number of functions (listed below) to ease your implementation. Click here to collapse and expand «

Function Parameter What it does?
renderChart() see above Returns a string containing HTML+JavaScript that renders a chart.
renderChartHTML() see above Returns a string containing HTML that renders a chart. This function is deprecated.
FC_SetDataFormat() "xml" or "json" Sets the data format for the data-source of the chart. The data-source is set through dataStr or dataUrl parameter of renderChart or renderChartHTML.

Default value is xml. When you set the value to json you need to pass JSON URL or JSON String through dataUrl or dataStr parameter.

You need to call this function each time before you call renderChart or renderChartHTML function.
FC_SetRenderer() "flash" or "javascript" Sets the renderer-engine of FusionCharts. It can be flash (default value). When you set the value to javascript, you can force-set javascript renderer.

You need to call this function each time before you call renderChart function.

This setting is not applicable while using renderChartHTML function.
FC_EnablePrintManager()   This function helps you enable the managed print feature of FusionCharts XT for Mozilla- browsers. It returns a <script> tag . You need to write the string in your page.You need to call this only once in a page.

Note: Print Manager works only in browsers that supports canvas object.
FC_SetWindowMode() "window" or "transparent" or "opaque" Sets window mode of a chart. By default, chart renders in "opaque" mode. You can set to it "window" if you required.

You need to call this function each time before you call the renderChart or renderChartHTML function.

So, you just saw how simple it is to create a chart using PHP and FusionCharts XT. Let's now convert the above chart to use the Data String method.
Changing the above chart into a single page chart using Data String method

To convert this chart to use the data string method, we create another page dataXML.php in the same folder with following code: 

<?php      
      //We have included ../Includes/FusionCharts.php, which contains functions
      //to help us easily embed the charts.
      include("../Includes/FusionCharts.php");
      ?>
      <HTML>
         <HEAD>
            <?php
      //You need to include the following JS file, if you intend to embed the chart using JavaScript.
      //When you make your own charts, make sure that the path to this JS file is correct. Else, you
      //will get JavaScript errors.
      ?> 
      <SCRIPT LANGUAGE="Javascript" SRC="../../FusionCharts/FusionCharts.js"></SCRIPT>
      <TITLE>FusionCharts XT - Simple Column 3D Chart using dataStr method</TITLE> 
     </HEAD>
  <BODY>
      <?php
           //Create an XML data document in a string variable
           $strXML  = "";
           $strXML .= "<chart caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units' showValues='0' formatNumberScale='0' showBorder='1'>";
           $strXML .= "<set label='Jan' value='462' />";
           $strXML .= "<set label='Feb' value='857' />";
           $strXML .= "<set label='Mar' value='671' />";
           $strXML .= "<set label='Apr' value='494' />";
           $strXML .= "<set label='May' value='761' />";
           $strXML .= "<set label='Jun' value='960' />";
           $strXML .= "<set label='Jul' value='629' />";
           $strXML .= "<set label='Aug' value='622' />";
           $strXML .= "<set label='Sep' value='376' />";
           $strXML .= "<set label='Oct' value='494' />";
           $strXML .= "<set label='Nov' value='761' />";
           $strXML .= "<set label='Dec' value='960' />";
           $strXML .= "</chart>";
           //Create the chart - Column 3D Chart with data from strXML variable using dataStr method
           echo renderChart("../../FusionCharts/Column3D.swf", "", $strXML, "myNext", 600, 300, false, true);
        ?>
  </BODY>
  </HTML>

As you can see above, we have:

  1. Included the FusionCharts.php file to render charts easily
  2. Included the FusionCharts.js file
  3. Creates the XML data document in a PHP variable strXML using string concatenation. Here, we are manually coding the data. In your applications, you can build this data dynamically after interacting with databases or external sources of data
  4. Finally, created the chart and set the dataStr parameter as strXML. We leave the dataUrl parameter blank.

When you see this chart, you will get the same results as before.

Using FusionCharts HTML embedding method to render chart

You can also create charts using HTML embedding method. It creates HTML <object>/<embed> tags to render chart. It does not require the FusionCharts.js to be included in the page.

HTML embedding method is deprecated. Many of the features of FusionCharts XT that works in collaboration with JavaScript, like providing JSON data, advanced event-handing, setting chart attribute etc., will not work using this method.

Again, to make things simpler for you, we have provided a PHP function called the renderChartHTML() which helps you render chart using the <object>/<embed> tag and you do not have to get your hands dirty with HTML tags. This function is also contained in the previously used FusionCharts.php file.

Let's now quickly put up a sample to show the use of this function. We make a copy of our SimpleChart.php (which rendered the chart using the Data URL method from Data.xml file) file and rename it to BasicChart.php. We load the data from our previously created Data.xml file. The modification involves a single line change from the previous file and the modified code (modification in bold) will look like the following : 

<?php      
    //We have included ../Includes/FusionCharts.php, which contains functions
    //to help us easily embed the charts.
      include("../Includes/FusionCharts.php");
      ?>
      <HTML>
      ...
   <?php
   //Create the chart - Column 3D Chart with data from Data/Data.xml
   echo renderChartHTML("../../FusionCharts/Column3D.swf", "Data/Data.xml", "", "myFirst", 600, 300, false, true);
   ?>
</BODY>
</HTML>

As you can see above, we have:

  1. Included the FusionCharts.php file.
  2. Created the chart using the renderChartHTML() method.

The renderChartHTML() method takes in the same parameters as the renderChart()function.

The above example shows how you can load data using Data Url method. You can always use Data String method to pass XML as string using renderChartHTML() method.
Create pure JavaScript charts

FusionCharts XT allows you to create pure JavaScript-only charts that does not require Flash, hence enabling your chart in browsers where Flash is not supported like that of iPhone, iPad, etc. This is achieved by calling the FC_SetRenderer() function in PHP before you render your chart. Using this function you need to set the current chart renderer to javascript.

The code snippet below shows how you can achieve this:

FC_SetRenderer( "javascript" );
  ...
echo renderChart("../../FusionCharts/Column2D.swf", "Data/Data.xml", "", "chart1", 600, 300, false, true);

The above code will create pure-JavaScript FusionCharts as shown in the image below:

FusionCharts pure JavaScript chart
Use JSON data to create chart

You can provide chart data in JSON format. You need to call the FC_SetDataFormat() function and set the data format to 'json' through it. Once done, you can pass the JSON data through the renderChart() function. If you need to pass JSON data contained in a URL, use the dataUrl parameter. If you have JSON as string, use dataStr parameter. The code snippets below illustrate how you can do these: 

// set chart data format to json 	
FC_SetDataFormat("json"); 	
//Create the chart - Column 3D Chart with data from Data/Data.json 	
echo renderChart("../../FusionCharts/Column3D.swf", "Data/Data.json", "", "myFirst", 600, 300, false, true);

or

// set chart data format to json 	
FC_SetDataFormat("json"); 	
//Create the chart - Column 3D Chart with data from strJSON variable using dataStr method 	
echo renderChart("../../FusionCharts/Column3D.swf", "", $strJSON, "myNext", 600, 300, false, true);

FusionCharts XT needs JSON to be passed in a specific format. Please read FusionCharts XT Data Formats > JSON section for more on this.

Please note that JSON data format is not supported in the renderChartHTML() function.

Create multiple charts in a single page

Creating multiple charts in a page is as easy as creating a single chart. The code below shows how you can call the renderChart() function and create as many charts as you wish. All you need to take care is that you should set unique chart id to each chart as highlighted in bold below: 

//Create the chart - Column 3D Chart with data from Data/Data.xml 	
echo renderChart("../../FusionCharts/Column3D.swf", "Data/Data.xml", "", "chart1", 600, 300, false, true); 
//Now, create a Column 2D Chart 	
echo renderChart("../../FusionCharts/Column2D.swf", "Data/Data.xml", "", "chart2", 600, 300, false, true); 
//Now, create a Line 2D Chart  
echo renderChart("../../FusionCharts/Line.swf", "Data/Data.xml", "", "chart3", 600, 300, false, true);
 
Create transparent chart

You can create charts with transparent backgrounds. This makes the chart show to what lies below it in HTML. To do this you need to follow these steps:

  1. In the chart's XML data, set <chart ... bgAlpha='0,0' ..>
  2. In the renderChart/renderChartHTML function set allowTransparent parameter to true.

Below is a sample code with a chart having transparent background :

<?php
//We have included ../Includes/FusionCharts.php, which contains functions
//to help us easily embed the charts.
include("../Includes/FusionCharts.php");
?>
<HTML>
  <HEAD>
    <SCRIPT LANGUAGE="Javascript" SRC="../../FusionCharts/FusionCharts.js"></SCRIPT>
  </HEAD>
  <BODY>
   <div style="padding:40px; background-color:#9d7fbd; border:1px solid #745C92; width: 600px;">
    <?php
      $strXML = "<chart bgAlpha='0,0' canvasBgAlpha='0' caption='Monthly Unit Sales' xAxisName='Month' yAxisName='Units'>";
      $strXML .= "<set label='Jan' value='462' />"; 
      $strXML .= "<set label='Feb' value='857' />"; 
      $strXML .= "<set label='Mar' value='671' />";
      $strXML .= "<set label='Apr' value='494' />";
      $strXML .= "<set label='May' value='761' />";
      $strXML .= "<set label='Jun' value='960' />";
      $strXML .= "<set label='Jul' value='629' />";
      $strXML .= "<set label='Aug' value='622' />";
      $strXML .= "<set label='Sep' value='376' />";
      $strXML .= "<set label='Oct' value='494' />";
      $strXML .= "<set label='Nov' value='761' />";
      $strXML .= "<set label='Dec' value='960' />";
      $strXML .= "</chart>";

      echo renderChart("../../FusionCharts/Column3D.swf", "", $strXML, "myFirst", 600, 300, false, true, true);
    ?>
   </div>
  </BODY>
</HTML>

In the code above we have:

  • Created a DIV with purple background -background-color:#9d7fbd;
  • Built a string XML for chart setting attributes bgAlpha='0,0' and canvasBgAlpha='0'
  • Rendered the chart with the allowTransparent parameter set to true and used the XML data created
  • Rendered the chart inside the purple DIV

The chart will look as shown below. The purple color of the DIV below the chart is visible through the body of the transparent chart.

FusionCharts pure JavaScript chart

Set managed printing for Mozilla browsers

FusionCharts XT provides better-print feature for all Mozilla, WebKit, and Gecko based browsers like Firefox, Safari, etc. To enable this feature in PHP all you need to do is call the FC_EnablePrintManager() function once in your page(preferably at the beginning or end). This will enable the print manager to process print data from all the charts in a page and prepare the charts for better-quality printing. To read more on how print manager works, please go through this.

Note: Print Manager works only in browsers that supports canvas object.

The code below shows how you need to enable print manager through PHP:

echo FC_EnablePrintManager();
...
// render chart
echo renderChart("../../FusionCharts/Column3D.swf", "Data/Data.xml", "", "chart1", 600, 300, false, true);

Listening to Print Manager status using JavaScript

Print Manager takes a bit of time to prepare all charts present in a page for print. You can listen to Print Manager's Ready State event using FusionCharts JavaScript class. Once the charts are ready, which can be tracked by listening to an event raised by the Print Manager, you can use browser's File → Print menu, JavaScript's native window.print() function or Print Manager's advanced function - managedPrint(). The JavaScript code below shows how you can listen to the event and prepare for print:

<html>
...
  <body>
  <script type="text/javascript"><!-- 					
      FusionCharts.addEventListener ( 
          FusionChartsEvents.PrintReadyStateChange , 
          function (identifier, parameter) {
            if(parameter.ready){ 
               alert("Chart is now ready for printing.");
               document.getElementById('printButton').disabled = false;
            }
        });
    // --></script> 	   
    <input type="button" onclick="FusionCharts.printManager.managedPrint()"
        value="Managed Print" disabled="disabled" id="printButton" >
...
  </body> 
</html>

In the above code we have:

  • Added a JavaScript event-listener for the global event PrintReadyStateChange to the global JavaScript object - FusionCharts
  • Added a "Managed Print" button which will call FusionCharts.printManager.managedPrint(). The button is disabled when loaded.
  • When the event is fired, it provides the listener with event arguments. The parameters event argument contains a property ready. This returns true when the Print Manager is ready to print all charts in a page
  • Hence, in this event we can show the information alert and also enable the button, which was disabled prior to this.

Now, if you try printing from File → Print menu or using a button or function that call the window.print() function. You can also click "Managed Print" button to print the chart.

How Print Manager Works:
  • Once a chart is rendered, it silently gathers all the image data of the present state of the chart
  • It converts the image data into image using canvas HTML object
  • It hides the canvas image below the chart
  • When print is invoked, a parallel CSS based print media layout (using @media print ) is created
  • In this print media layout the Flash chart is hidden and the canvas image is displayed
  • This layout with the canvas image is sent to the printer for print
 
Creating Multi-series chart

Unlike the single set of data which we have plotted in the above charts, you might want to compare data of multiple months. In that case, you will need to create multi-series charts. In the sample below we will learn how to create a Multi-series chart having data for two years. The chart will look like the image shown below:

To create a multi-series chart, all you need to do are:

Let's take a sample Multi-series data with monthly sales figures of two years as shown below (saved as MSData.xml):

 
<chart caption='Business Results 2005 v 2006' xAxisName='Month' yAxisName='Revenue' showValues= '0'numberPrefix='$'>

           echo renderChart("../../FusionCharts/MSColumn3D.swf", "Data/MSData.xml", "", "myFirst", 600, 300, false, true);
        ?>
  </BODY>
  </HTML>

In the above code we have done the following:

  • Changed the chart SWF to MSColumn3D.swf
  • Changed the data as MSData.xml

The generated chart will be look the following screen-shot:

Please note that you can also use JSON data instead of XML. To achieve this, you will just need declare FC_SetDataFormat("json") and pass your data as JSON instead of XML as shown in Use JSON data to create chart section above.

Creating Stacked chart

You can also show the cumulative sales figures of each month in grouped column in stacked charts. It is very easy to create a Stacked chart once you are ready with a multi-series data as shown in the previous example. The stacked chart will render similar to the image shown below:

To render the above chart, you will only need to provide the same multi-series data as shown in the previous example and use a Stacked chart SWF file as shown in the code section below:

<%
   //Create chart - stacked Column 3D Chart with data from Data/MSData.xml     
   echo renderChart("../../FusionCharts/StackedColumn3D.swf", "Data/MSData.xml", "", "myFirst", 600, 300, false, true)    
%>
 
Creating a Combination chart

You can wish to combine various chart types and display in a single canvas. You can achieve this using a Combination chart.

To keep it simple, let's re-use the Multi-series data we used in the previous example. We will render the data for 2006 as a Column chart and data for 2005 as Area chart. The desired chart will be similar to the image shown below:

To achieve this, we have done the following modifications:

  • changed chart SWF file to MSCombi2D.swf

    echo renderChart("../../FusionCharts/MSCombi2D.swf", "Data/CSYData.xml", "", "myFirst", 600, 300, false, true)

  • added  renderAs='Area' in dataset for 2005 

    <dataset seriesName='2005' renderAs='Area' >
 
Creating a combination chart showing multiple units using Dual Y Axis chart

So far, we have been working with data having a single unit - revenue. However, it is also possible to combine a chart of another unit like Quantity using a Dual Y Axis chart.

Let's create a chart which shows total quantity sales in two years along with revenue of two years. The chart will look as follows:

To achieve this, we will need to use a Dual Y Axis chart SWF file. Additionally, we will also add another set of data containing the total quantity in XML or JSON. The data with revenue and total quantity data is as follows:

 
<chart caption='Business Results 2005 v 2006' xAxisName='Month' yAxisName='Revenue' showValues= '0'numberPrefix='$'>

      <set value='310' />
      <set value='430' />
      <set value='180' />
      <set value='260' />
      <set value='200' />
   </dataset>
</chart>

        { "value":"260"    },
        { "value":"200"    }
      ]
    }
  ]
}

The above data is derived from the multi-series example. We have done the following changes in this data (saved as CDYData.xml) :

  • We added a dataset with "Quantity" as seriesName
  • We set this dataset to render on the secondary y-axis using the parentYAxis attribute
 
The parentYAxis attribute allows you to set the parent axis of the dataset. The required value can be either P (primary axis) or S (secondary axis). Primary datasets are drawn against the left y-axis and the secondary against the right-axis. For more details please go through FusionCharts XT Data Format > XML > Combination Chart page.

The SWF file used to render a combination dual y-axis chart is MSCombiDY2D.swf and the HTML code used is as follows:

echo renderChart("../../FusionCharts/MSCombiDY2D.swf", "Data/CDYData.xml", "", "myFirst", 600, 300, false, true)
 
Creating other advanced charts

FusionCharts XT pack offers advanced chart types like Scatter, Bubble, multi-series Stacked, Pareto, Marimekko etc. which can be also created using the same method described above. All you will need to do is to follow the XML format of the required chart type and use the proper SWF name of that chart type while rendering the chart. The following list provides links to the XML API pages of all the advanced chart types:
