Stacked charts

Now, let's learn how to create a Stacked Chart. We will create a chart showcasing revenue split for each quarter of the current year by product category - food products and non-food products. The data will look as shown below:

Quarter Product Type Revenue(in USD)
Q1 Food Products 11000
Non-Food Products 11400
Q2 Food Products 15000
Non-Food Products 14800
Q3 Food Products 13500
Non-Food Products 8300
Q4 Food Products 15000
Non-Food Products 11800

The chart will look as shown below:

Render the Chart

Create the StackedChart.aspx.cs file and do the following:

  • Include the FusionCharts.DataEngine and FusionCharts.Visualization .dll files.
  • Create DataTable.
  • Add two columns and multiple rows to the DataTable.
  • Create a StaticSource using the DataTable.
  • Create an instance of DataModel class.
    • Add DataSource to the DataModel.
  • Instantiate Stacked chart.
  • Set chart width and height.
  • Set the type of stacked chart as BAR, COLUMN, or AREA.
  • Set DataModel instance as the data source of the chart.
  • Optionally, set chart title, subtitle, X-axis text, and Y-axis text.
  • Optionally, set the chart theme as fusion.
  • Return the chart rendering configuration into the server side literal, or set the chart configuration as Literal.text.
