Hello shikha,

I made a simple code that adds text to DataTable Tool using auxiliary series. Please see next code and check that works as you want.

Code: Select all

        public Form1()
        {
            InitializeComponent();
            InitializeChart();
        }
        private Steema.TeeChart.Styles.Bar bar1, bar2;
        private Steema.TeeChart.Tools.DataTableTool datatool1;
        private void InitializeChart()
        {
            bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            bar2 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
            datatool1 = new Steema.TeeChart.Tools.DataTableTool(tChart1.Chart);

            bar1.FillSampleValues();
            bar2.DataSource = bar1;
            bar2.Color = Color.Transparent;
            bar2.ShowInLegend = false;
            bar2.Title = "";
            for (int i = 0; i < bar1.Count; i++)
            {
                bar2[i].Label = "Total" + i.ToString();

            }
            datatool1.GetText += new Steema.TeeChart.Tools.DataTableEventHandler(datatool1_GetText);
        }

        void datatool1_GetText(Steema.TeeChart.Tools.DataTableTool sender, Steema.TeeChart.Tools.DataTableEventArgs e)
        {
            if (e.Series.Labels.Count > 0)
            {
                e.Text = e.Series.Labels[e.ValueIndex]; 
            }
        }

I hope will helps.

Thanks for the reply. I am using VB.net , so i converted it into that using a utility . But it generates an error- "Error -Type 'Steema.TeeChart.Tools.DataTableEventArgs' is not defined." when i run the program. I am using Teecahrt version -3.5.3470.15474 and the code after converting into vb.net is as follows-

Public Sub New()
InitializeComponent()
InitializeChart()
End Sub
Private bar1 As Steema.TeeChart.Styles.Bar, bar2 As Steema.TeeChart.Styles.Bar
Private datatool1 As Steema.TeeChart.Tools.DataTableTool
Private Sub InitializeChart()
bar1 = New Steema.TeeChart.Styles.Bar(tChart1.Chart)
bar2 = New Steema.TeeChart.Styles.Bar(tChart1.Chart)
datatool1 = New Steema.TeeChart.Tools.DataTableTool(tChart1.Chart)

bar1.FillSampleValues()
bar2.DataSource = bar1
bar2.Color = Color.Transparent
bar2.ShowInLegend = False
bar2.Title = ""
For i As Integer = 0 To bar1.Count - 1

bar2(i).Label = "Total" & i.ToString()
Next
AddHandler datatool1.GetText, AddressOf datatool1_GetText
End Sub

Private Sub datatool1_GetText(ByVal sender As Steema.TeeChart.Tools.DataTableTool, ByVal e As Steema.TeeChart.Tools.DataTableEventArgs)
If e.Series.Labels.Count > 0 Then
e.Text = e.Series.Labels(e.ValueIndex)
End If
End Sub

it generates this error at this line-
Private Sub datatool1_GetText(ByVal sender As Steema.TeeChart.Tools.DataTableTool, ByVal e As Steema.TeeChart.Tools.DataTableEventArgs)

Hello shikha,

it generates this error at this line-
Private Sub datatool1_GetText(ByVal sender As Steema.TeeChart.Tools.DataTableTool, ByVal e As Steema.TeeChart.Tools.DataTableEventArgs)

I could reproduce your problem using last version 3 of TeeChart.Net but not in version 4, because this event is new in version 4 and is not possible do same with version 3 of TeeChart.


Thanks,

Hi shikha,

If you are a TeeChart for .NET v3 license holder you can upgrade your license to TeeChart for .NET v2009 here:

[Neelam]

is the TeeChart for .NET v2009 and version 4 one and the same?

[Narcís]

Hi shikha,

Yes, it is the same. Internally it's v4 and 2009 is the commercial name.
