Remarks

WebChart is the central component in TeeChart library for Web Forms and is the container for all other TeeChart objects. The diagram below indicates the main TeeChart objects that can be accessed from the WebChart class:

WebChart objects can only be added to Web Forms at design-time by dragging the a WebChart component across a Web Form, although series can be added at both design and run-time; at run-time we could use:

[C#] 
private void Page_Load(object sender, System.EventArgs e) 
{     
     if(!((System.Web.UI.Page)sender).IsPostBack) { 
        Steema.TeeChart.Chart tChart1 = WebChart1.Chart; 
        Steema.TeeChart.Styles.Bar bar1 = new Steema.TeeChart.Styles.Bar(tChart1); 
        bar1.FillSampleValues(20); 
    } 
} 
 
[VB.Net] 
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
    If Not CType(sender, System.Web.UI.Page).IsPostBack Then 
        Dim TChart1 As Steema.TeeChart.Chart = WebChart1.Chart 
        Dim Bar1 As New Steema.TeeChart.Styles.Bar(TChart1) 
        Bar1.FillSampleValues(20) 
    End If 
End Sub

or...

[C#] 
private void Page_Load(object sender, System.EventArgs e) 
{     
     if(!((System.Web.UI.Page)sender).IsPostBack) { 
        Steema.TeeChart.Chart tChart1 = WebChart1.Chart; 
        tChart1.Series.Add(new Steema.TeeChart.Styles.Pie()); 
        tChart1.Series[0].FillSampleValues(20);     
    } 
} 
 
[VB.Net] 
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
    If Not CType(sender, System.Web.UI.Page).IsPostBack Then 
        Dim TChart1 As Steema.TeeChart.Chart = WebChart1.Chart 
        TChart1.Series.Add(New Steema.TeeChart.Styles.Pie()) 
        TChart1.Series(0).FillSampleValues(20) 
    End If 
End Sub

Any number of WebChart objects can co-exist on a single Web Form. To use TeeChart within a Windows Form environment please use the Steema.TeeChart.TChart class.
