Stacking bars

[Lars Iversen]

Hi

I have a chart with bar series.
I need to stack it using code. I can do it from the teechart editor but I really need to do it in code.
I'm using VB
I have tried this:

Dim mybar As Steema.TeeChart.Styles.MultiBars = CType(tChart.Series(0), Steema.TeeChart.Styles.Barmultibars)
mybar.Stacked = Steema.TeeChart.Styles.MultiBars.Side

But it does not allow me to do the conversion in the first line. It tells me:
Type: Steema.TeeChart.Styles.MultiBars Not defined

What Am I doing wrong?

Thanks in advance

Hi Lars,

You need tu use MultiBar property like this:

Code: Select all

        Dim bar1 As New Steema.TeeChart.Styles.Bar(TChart1.Chart)
        bar1.MultiBar = Steema.TeeChart.Styles.MultiBars.Side

Hi Narcís

Thanks that seems to work, but then again maybe not.
The code runs but series do not get stacked ( The stay the same.
Is it a bug that might be fixed. I'm using version: 2.0.2306.26232
I have to use this version because of a lot of other problems I have with the newer ones. (Its mostly about streaming to ten and back)

anyway do you have any other suggestions on how to get my bar series stacked?

Thanks in advance

Hi Lars,

Code below works fine for me here using latest TeeChart for .NET v2 build available. Could you please check if this version solves the problems at your end?

Code: Select all

        For index As Integer = 0 To 3
            Dim bar1 As New Steema.TeeChart.Styles.Bar(TChart1.Chart)
            bar1.MultiBar = Steema.TeeChart.Styles.MultiBars.Side
            bar1.FillSampleValues()
        Next

Code: Select all

I have to use this version because of a lot of other problems I have with the newer ones. (Its mostly about streaming to ten and back) 

Which are the exact problems you are having with newer versions? If you already reported them could you please post the forums thread where they were discussed?

Thanks in advance.

Ahh sorry. I can now see the problem. the example you gave me creates a new bar series and makes sure they are stacken and THEN the data is filled. that works fine too in a small example I have made now.

I have it the other way around. When my customer wants to stack. the bar series has already been made in the chart. So I have to make the bar series stacked after they are filled. Somehow I need to go through the existing series and make them stacked. can you give an example of that?

Regarding the other issues I have with newer versions: I have tried to do a search where I put in "Lars Iversen" as author but it does not return anything. But in short: I have some advanced code that builds up database queries runtime and adds data and a lot of formatting to the chart. then I can't export the chart as a stream. I get some kind of error that some string could not be converted to numeric or something like that. I can not make a small example that will simulate it (

Hi Lars,

Sure, you can make something like this:

Code: Select all

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        For Each b As Steema.TeeChart.Styles.Series In TChart1.Series
            If (TypeOf b Is Steema.TeeChart.Styles.Bar) Then
                CType(b, Steema.TeeChart.Styles.Bar).MultiBar = Steema.TeeChart.Styles.MultiBars.Side
            End If
        Next

    End Sub

Regarding the other issues, what about searching here?
