In this method, the entire chart data (XML or JSON) is provided as a string and embedded into the same page as the chart. When a chart renders or gets updated in a page, it reads the chart data from the string and then renders the chart. The following diagram (along with the steps described below) will help you understand better:

  1. Unlike the Data URL method, here, the entire XML or JSON data is embedded in the web page containing the chart. The data can be embedded in various ways like:
    • The data can be generated from dynamic data-sources like database etc. using server-side scripts and embedded into the web page (while creating the page)
    • The data can be generated in the page itself using JavaScript without external dependencies (e.g., when creating a chart from HTML Form)
    • The data can be acquired using various Web API's, AJAX responses and stored as string in the page itself
  2. Once the chart is loaded on the end user's machine or a chart's data needs to be updated, it reads the XML/JSON string or JSON object embedded into the page using JavaScript functions
  3. And finally, the desired chart is rendered!

Effectively, in this process you need the following to build a chart:

  1. Chart Container page - The page that contains the HTML code required to embed the chart. It also contains the XML/JSON data to be used by the chart.
  2. Chart SWF file - SWF file for the chart that you wish to render. Each chart in FusionWidgets XT is an SWF file that creates a specific type of chart. For example, if you want to create a real-time angular gauge, you'll need the AngularGauge.swf file.
  3. Javascript files - These files help in embedding the chart SWF file in your HTML page and also rendering JavaScript (HTML5) charts. The required files are - FusionCharts.js, FusionCharts.HC.js, FusionCharts.HC.Widgets.js and jquery.min.js.
Sample usage of Data String method using FusionCharts JavaScript Class
<div id="chart1div">
   This text is replaced by the chart.
<script type="text/javascript">
   var chart1 = new FusionCharts("AngularGauge.swf", "ChId1", "600", "400", "0", "1");
   chart1.setXMLData("<chart><set label='Data1' value='1' /></chart>");

FusionCharts JavaScript Class provides other functions to achieve the same : setJSONData, setChartData, setDataXML (deprecated)

Using various server-side scripts

To ease embedding of charts in your web pages, FusionWidgets XT provides wrapper classes (FusionCharts wrapper classes) ready for various server-side scripts like Classic ASP, ASP.NET C#, ASP.NET VB.NET, PHP, J2EE, Ruby on Rails and ColdFusion.

FusionCharts wrapper classes are present in FusionCharts XT pack. If you do not have the licensed pack of FusionCharts XT, you can directly download the trial version of FusionCharts XT and get the fully functional wrapper classes from the pack. The wrapper classes are present in the FusionCharts XT Download Pack's Code folder.

Here, we provide highlights of code snippets that are used in each technology to embed FusionWidgets XT using Data String method.
