Create Multivariate chart

In FusionCharts, you can create a time-series chart with multiple canvases showing different measures in each canvas.

In this article, we will create a multivariate chart showcasing the database of the Global SuperStore. The chart contains multiple columns with measures (Sales, Quantity, Shipping cost) rendered on separate canvases. All the three canvases share the same time axis (X-axis).

The multivariate chart will look as shown below:

The sample data for the above chart is shown in the table below:

Order Date	Sales	Quantity	Shipping Cost
1/1/2011	120.366	3	9.72
1/3/2011	113.67	5	4.70
1/5/2011	55.242	2	1.80
1/6/2011	6.54	1	1.13
1/7/2011	5.48	2	0.52
1/8/2011	76.728	3	6.69

Render the chart

Now that you have the data handy, let's build the chart.

Create the DataHandler.ashx file and do the following:

Include the FusionCharts.DataEngine.dll file.
Include the FusionCharts.Visualization.dll file.
Set response content type as "application/json".
Create an object of the DataModel class.
Convert the model to a data format the time series can accept.
Write the converted data into a JSON file.

Refer to the code given below:


using FusionCharts.DataEngine;
using FusionCharts.Visualization;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace FcTest
{
    /// 
    /// Summary description for DataHandler
    /// 
    public class DataHandler : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {

            DataModel model = new DataModel();


            CsvFileSource source = new CsvFileSource("https://raw.githubusercontent.com/fusioncharts/dev_centre_docs/master/assets/datasources/fusioncharts-net/OnlineSalesMultiVariate.csv");


            model.DataSources.Add(source);


            context.Response.Write(TimeSeriesData.RenderCompatibleDataInJson(model,suppress,”chartId”));
        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}


Imports FusionCharts.DataEngine
Imports FusionCharts.Visualization
Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Web

Namespace FcTest
    Public Class DataHandler
        Implements IHttpHandler

        Public Sub ProcessRequest(ByVal context As HttpContext)
            Dim model As DataModel = New DataModel()
            Dim source As CsvFileSource = New CsvFileSource("https://raw.githubusercontent.com/fusioncharts/dev_centre_docs/master/assets/datasources/fusioncharts-net/OnlineSalesMultiVariate.csv")
            model.DataSources.Add(source)
            context.Response.Write(TimeSeriesData.RenderCompatibleDataInJson(model,suppress,”chartId”))
        End Sub

        Public ReadOnly Property IsReusable As Boolean
            Get
                Return False
            End Get
        End Property
    End Class
End Namespace

Next, create the Multivariate.aspx.cs or Multivariate.aspx.vb file and do the following:

Include the FusionCharts.Visualization .dll file.
Initialize the TimeSeriesChart object of the Charts class.
Provide the data handler filename ("DataHandler.ashx") as the value of the SourcePathHandler property of the Data object of the timeSeries class.
Provide the value of the Render() method to the Text property of Literal1.


using FusionCharts.DataEngine;
using FusionCharts.Visualization;
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace FcTest
{
    public partial class ChartTest : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Charts.TimeSeriesChart timeSeries = new Charts.TimeSeriesChart("first_timeseries");
            timeSeries.Data.SourcePathHandler = @"DataHandler.ashx";
            timeSeries.Width.Pixel(700);
            timeSeries.Height.Pixel(500);
            timeSeries.MultiCanvas.Enable = true;
            Literal1.Text = timeSeries.Render();
        }
    }
}

Imports System.Collections.Generic

Imports System.Linq

        Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
            Dim timeSeries As Charts.TimeSeriesChart = New Charts.TimeSeriesChart("first_timeseries")
            timeSeries.Data.SourcePathHandler = "DataHandler.ashx"
            timeSeries.Width.Pixel(700)
            timeSeries.Height.Pixel(500)
            timeSeries.MultiCanvas.Enable = True
            Literal1.Text = timeSeries.Render()
        End Sub
    End Class
End Namespace

Next, open the Multivariate.aspx file and add the following line to it:

<asp:Literal ID="Literal1" runat="server"></asp:Literal>

Refer to the code given below:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
  <head runat="server">
    <title></title>
    <script
      type="text/javascript"
      src="//cdn.fusioncharts.com/fusioncharts/latest/fusioncharts.js"
    ></script>
    <script
      type="text/javascript"
      src="//cdn.fusioncharts.com/fusioncharts/latest/fusioncharts.timeseries.js"

    <script
      type="text/javascript"
      src="//cdn.fusioncharts.com/fusioncharts/latest/themes/fusioncharts.theme.fusion.js"
    ></script>
  </head>

  <body>
    <script></script>

    <form id="form1" runat="server">

        <asp:Literal ID="Literal1" runat="server"></asp:Literal>
      </div>
    </form>
  </body>
</html>

You can render the above multivariate chart in a single canvas.

The chart looks like as shown below:

The .ashx and .aspx files for the single canvas multivariate chart is goven below:

All the other steps to render the single canvas multivariate chart is same as that of multivariate (multi-canvas) chart.
