space isssue

[Neelam]

hey, thanks so much for sending the solution. I tried the code , the only issue is now taht i have vb.net and this is in c sharp. so i tried to convert it, but at this line
tChart1.GetAxisLabel += new Steema.TeeChart.GetAxisLabelEventHandler(tChart1_GetAxisLabel);

it gives error.. it sauys use raoise event.. but when i use taht it does not take.
Can u send me its equivalent vb.net code. thanks so much for ur help.

i tried to convert using a utility..
Private Sub InitializeChart()
chartController1.Chart = tChart1

tChart1.Series.Add(New Steema.TeeChart.Styles.Bar())
tChart1.Series(0).Add(123, "really long long label 1", Color.Red)
tChart1.Series(0).Add(456, "really long long label 2", Color.Blue)
tChart1.Series(0).Add(321, "really long long label 3", Color.Green)

tChart1.Axes.Bottom.Labels.Angle = 90

tChart1.GetAxisLabel += New Steema.TeeChart.GetAxisLabelEventHandler(tChart1_GetAxisLabel)
End Sub

Private Sub tChart1_GetAxisLabel(ByVal sender As Object, ByVal e As Steema.TeeChart.GetAxisLabelEventArgs)
If e.LabelText.Length > 16 Then
Dim tmp1 As String = e.LabelText.Substring(0,16)
Dim tmp2 As String = e.LabelText.Substring(16,e.LabelText.Length-16)

e.LabelText = String.Format("{0}{1}{2}", tmp1, "\n", tmp2)
End If
End Sub

'BUT it gives error - Use a raiseevent statement to raise an event at this line- " tChart1.GetAxisLabel += New Steema.TeeChart.GetAxisLabelEventHandler(tChart1_GetAxisLabel)"

Hello shikha,

The example code of VB is next:


Form_Load:

Code: Select all

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        InitializeChart()
    End Sub

InitializeChart:

Code: Select all

    Private Sub InitializeChart()
        ChartController1.Chart = TChart1

        TChart1.Series.Add(New Steema.TeeChart.Styles.Bar())
        TChart1.Series(0).Marks.Visible = False
        TChart1.Series(0).Add(123, "really long long label 1", Color.Red)
        TChart1.Series(0).Add(456, "really long long label 2", Color.Blue)
        TChart1.Series(0).Add(321, "really long long label 3", Color.Green)
        TChart1.Axes.Bottom.Labels.Angle = 90
    End Sub

GetAxisEvent:

Code: Select all

  Private Sub tChart1_GetAxisLabel(ByVal sender As Object, ByVal e As Steema.TeeChart.GetAxisLabelEventArgs) Handles TChart1.GetAxisLabel
        If e.LabelText.Length > 16 Then
            Dim tmp1 As String = e.LabelText.Substring(0, 16)
            Dim tmp2 As String = e.LabelText.Substring(16, e.LabelText.Length - 16)

            e.LabelText = String.Format("{0}{1}{2}", tmp1, vbCrLf, tmp2)
        End If
    End Sub

I have assigned GetAxisLabels event at design time, because it's more easy. Please check that this code works fine.


I hope that will helps.

Thanks,

great this works but..
just one thing it pushes the chart up(that is make size of chart smaller). But the whole idea of doing this is taht the chart size does not change and does not become small.Infact there is lot of empty space belowthe labels in this case. how can we resolve that?

Hi shikha,

Try playing with the following properties until you'll find your desired combination:

Code: Select all

TChart1.Panel.MarginBottom = 0
Chart1.Axes.Bottom.RelativePosition = -12

[Neelam]

where exactly these 2 lines should be placed .. i mean at which event?

[Yeray]

Hi shikha,

In a beginning you should modify your chart aspect at chart creation. If your labels change at any event, maybe you should do some calculations and change your chart aspect there.

Hi shikha,

For topic consistency and so that it is easier for everyone to follow each topic I splitted your last post into another thread as it's a problem different from what was originally discussed here. You can follow the new thread here:

We will appreciate that you start a new thread for each different technical inquiry not related to an existing topic.

Thanks in advance.

Hi shikha,

Sorry, I wrongly splitted the first topic instead of the last, new topic is this one:
