Line, Area and Column Charts

Column 2D Chart

Column and bar charts represent data with rectangular horizontal or vertical bars. The height of the bars is proportional to the values they represent. In case of a column chart, the numeric values are plotted along the y-axis, and the data labels are plotted along the x-axis. Whereas in bar charts, the numeric values are plotted along the x-axis, and the data labels are plotted along the y-axis. Column and bar charts are best fitted when you want to compare values.

In this sample, let's create our first column chart showcasing the monthly revenue for last one year for Harry's SuperMart. We have plotted the months along the x-axis and the revenue, which is a numeric value, along the y-axis.

To create a single-series column 2D chart, follow the steps given below:

  • In the JSON data, set the attributes and their corresponding values in "<attributeName>": "<value>" format.

  • Specify the chart type using the type attribute. To render a column chart, set column2d.

  • Set the container object using renderAt attribute.

  • Specify the dimension of the chart using width and height attributes.

  • Set the type of data (JSON/XML) you want to pass to the chart object using dataFormat attribute.

  • Depending on the value passed to the dataFormat, set the dataSource attribute (JSON/XML) from where the data will be fetched.

  • Specify the value for a data item using the value attribute within the data object.

For a detailed list of attributes, refer to the chart attributes page of column 2D chart.

Line Chart

Line charts are commonly used to showcase the trend in data over time whereas area charts are used to display quantitative data. Information in a line or area chart is plotted on the x- and y-axis; data values are plotted using data points that are connected using line segments.

In the sample, let's create a line chart showcasing total footfall at Bakersfield Central. We have plotted the days along the x-axis and the number of visitors along the y-axis.

To render a line chart, set the type attribute to line.

For a detailed list of attributes, refer to the chart attributes page of line chart.

Area Chart

An area chart is similar to the line chart, with the difference that the area marked by the anchors and line segments is filled.

Now, let's customize the appearance and properties of the charts.

Plot Trend Elements

The trend elements on a chart include trendlines and trendzones.

Trendlines are horizontal or vertical reference lines, which aid in interpretation of data. They can be used to set context or define limits and targets. For example, while plotting quarterly sales of a company, you might want to use a trendline to depict the target sales. Trendzones are similar to trendlines except that they mark out an entire zone rather than just a line.

To plot a trendline on a chart, follow the steps given below:

  • Create a trendlines object to render one or more than one trendline.

  • Create a line object for a particular trendline.

  • In line object, set the startValue attribute to specify the starting value for the trendline. Set the endValue to specify the end value for the trendline.

  • Set the color attribute to specify the hex code for the color. Use this attribute to render the trendline and its associated text.

  • Set the displayValue attribute to display a string caption with the trendline.

Given below is the JSON code to include trendline on your chart:

{
    "chart": {
        ...
    },
    "data": [],
    "trendlines": [{
        "line": [{
            "startvalue": "175000",
            "color": "#29C3BE",
            "displayvalue": "Target - $175K"
        }]
    }]
}

A quarterly sales summary chart rendered with a trendline to show the target value looks like this:

Trendzone is used to show a range of target values. The trendzone uses the same attributes as the trendline. isTrendZone is the attribute which is used to specify whether a chart will be rendered with a trendline or a trendzone. Setting this attribute to 0 will render a trendline, setting it to 1 (default) will render a trendzone.

Plot Vertical Line Elements

Vertical (or horizontal in case of bar charts) separator lines are elements that can differentiate between data blocks in a chart. They can be placed between any two data points or can be aligned to specific data points.

To plot vertical line in your chart, follow the steps given below:

  • Set the vLine attribute to true to render a vertical line on the chart.

  • Specify the label attribute to set the label for the vertical line. This label will be rendered along the x-axis.

  • Set the position of the vertical line using linePosition attribute. This attribute is positioned relative to the two data points between which it is to be plotted.

Given below is the JSON code to include a vertical line on your chart:

{
  "chart": {
      ...
  },
  "data": [],
  "trendlines": [
    {
      "line": [
        {
          "vline": "true",
          "label": "Weekend Start",
          "color": "#29C3BE",
          "linePosition": "0.7"
        }
      ]
    }
  ]
}

Change Chart Type

FusionCharts Suite XT allows you to change the chart type dynamically through its advanced API. You can change chart type by calling the chartType() method on any FusionCharts' instance and provide the chart name as an argument.

An example of a chart, where you can dynamically change the chart type, looks like this:

Data Skipping

Visualization plays a crucial role in data science, helping data scientists to make sense of the underlying patterns within data, even before any other computation begins. With v3.12.0, FusionCharts has evolved to consume a large amount of data in standard charts.

What if you want to render 10000 data points in a single series chart with a dimension of 500x400 pixels for the line, area, and column charts. So if we take the width of the canvas as 500 pixels, an average of 20 data plots will be drawn every width of a pixel which is not very informative with respect to visualization.

Data skipping is a concept which has been introduced to draw only those plots in the canvas which actually creates a data trend without hampering the performance of the chart.

Given below is the list of attributes with the help of which you can customize your data skipping:

  • Set plotBinSize attribute to 1, to render minimum one data plot within the width of one pixel. Example, if plotBinSize: 1, minimum one column plot will be rendered within the width of one pixel. For line and area charts, minimum of two anchors connecting one single line will be drawn. If plotBinSize: 0.5, minimum two column plot on each pixel (width )will be rendered.

  • Set the labelBinSize attribute to 1, to display minimum one label in the width of one pixel.

To disable this label skipping, set this attribute to 0.

Now, let's render an area chart with 30000 data. You will notice that the chart will give a clear idea on how frequently the new trips are availed. The chart will show the data updated every hour. The chart plots with maximum and minimum value in a single pixel (width), drawn to show the pattern out of data. The plots get overlapped only if they are hidden by another plot which results to render the chart much faster than expected. The overlapping takes place based on the data trend which cannot be compromised.

An example will look like as shown below:

In multi-series chart, one dataset can be overlapped (partially or completely) by another dataset only if the data plot of one dataset gets hidden by the other.
