Render the Chart

Create the FunnelChart.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 StaticSource as data source to the DataModel.
  • Instantiate Funnel chart.
  • Set chart width and height.
  • 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.
