Hello.
We upgrade tee chart from TeeChart2010.0.0.3ActiveX to TeeChart2011.0.0.4ActiveX.
Please take a look at the following pictures.
The x axis lables are in a mess.

2011.png : TeeChart2011.0.0.4ActiveX
Can you tell me how to fix this ?

Hi,
Then I'm afraid I'll have to ask you for a simple example project we can run as-is to reproduce the problem here.
Thanks in advance.

Hi,
What about forcing the bottom axis to show the values instead of the labels?
Code: Select all
tChart.Axis.Bottom.Labels.Style = EAxisLabelStyle.talValue;
Alternatively, the latest version where this changed in AX was with v2011.04, so with v2010.03 the problem that is affecting you wasn't reproducible (problem #1 mentioned
here).

Hello.
Thanks for your help.
Line chart is ok with
Code: Select all
tChart.Axis.Bottom.Labels.Style = EAxisLabelStyle.talValue;
As for point chart. Value is no meaning for us. We would like to show text in X axis label.
2010 version is no problem.
2011 version is not good for me.

Hi,
With v2011.0.0.4 or v2011.0.0.5, the only solutions I see:
- Only add one series with labels. In your example, if I change the second series loop for this, it seems to work fine:
Code: Select all
for (int i = 0; i < 50; i++)
iSeries.AddXY(i + 0.5, 2, /*"second" + i*/ "", 0x0000ff);
- Use custom labels instead of letting talText to draw all the labels of all the series. Adding this at the end of your Main method (just before exporting the chart to png) it seems to work fine:
Code: Select all
tChart.Environment.InternalRepaint();
int lastpos = 0;
tChart.Axis.Bottom.Labels.Clear();
for (int i = 0; i < tChart.Series(0).Count; i++)
{
if ((lastpos == 0) || (tChart.Axis.Bottom.CalcXPosValue(tChart.Series(0).XValues.Value[i]) - lastpos > 10))
{
tChart.Axis.Bottom.Labels.Add(tChart.Series(0).XValues.Value[i], tChart.Series(0).PointLabel[i]);
lastpos = tChart.Axis.Bottom.CalcXPosValue(tChart.Series(0).XValues.Value[i]);
}
}
