Bug in axes / chart editor

Hi,
just found another bug in chart editor. It makes work extremly hard. The first image shows the initial state after showing the axis editor and selecting the x axis:
- test5.JPG (48.26 KiB) Viewed 6549 times
The following image represents the situation after only one click on the labels tab:
- test6.jpg (49.07 KiB) Viewed 6551 times
Obviously, by only changing the active tab page the formate string has been changed. That's terribly and highly confusing for the end user!
I assume you will get the same situation by using an empty project and data values in the same x values range.
What to do?
BTW: Is there a possibility to select the active axis by code? For instance, double click on the x axis should open the editor with x axis ready to format. Preferably, the other axis could be invisible.

I'm trying to reproduce it with the following code but I can't. I'm probably missing some relevant setting, do you see what?
Code: Select all
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
Steema.TeeChart.Styles.FastLine fast1 = new Steema.TeeChart.Styles.FastLine(tChart1.Chart);
Random r=new Random();
fast1.Add(-1.276*0.0000001, r.Next(100));
for (int i = 1; i < 10000; i++)
{
fast1.Add(fast1.XValues[i-1] + 0.01, fast1.YValues[i-1] + r.Next(10) - 4.5);
}
tChart1.Axes.Bottom.Labels.ValueFormat="#E+00";
}

You could do it as follows:
Code: Select all
void tChart1_MouseDoubleClick(object sender, MouseEventArgs e)
{
if (tChart1.Axes.Bottom.Clicked(e.X,e.Y))
{
Steema.TeeChart.Editors.AxisEditor editor1 = new Steema.TeeChart.Editors.AxisEditor();
editor1.Axis = tChart1.Axes.Bottom;
editor1.ShowDialog();
}
}

Hi Narcis,
You could do it as follows:
Thanks, I have overlooked that there is an AxisEditor Besides AxesEditor...
I'm trying to reproduce it with the following code but I can't. I'm probably missing some relevant setting, do you see what?
Code: Select all
tChart1.Axes.Bottom.Labels.ValueFormat="#E+00"
Without the code line above you will get a x axis which looks like in test6.jpg. In order to come to an axis scale as in test5.jpg you can use in the axis editor an empty format string or "g". If you choose the empty string the things occur as described in my former message. So I did yesterday. I just figured out that with "g" the things are OK. So the chart editor should use "g" in the case of an empty format string.
Best regards
Uli

Hi Uli,
What I've reproduced and added to the defect list to be fixed in future releases (TF02015032) is the following:
With the code below, you can see something like when the application starts:
- first.png (39.16 KiB) Viewed 6523 times
Then, if you open the editor and go to the Chart\Axes (Bottom Axis)\Labels, the bottom axis labels change to this:
- second.png (41.35 KiB) Viewed 6522 times
Code:
Code: Select all
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
Steema.TeeChart.Styles.FastLine fast1 = new Steema.TeeChart.Styles.FastLine(tChart1.Chart);
Random r = new Random();
fast1.Add(-1.276 * 0.0000001, r.Next(100));
for (int i = 1; i < 10000; i++)
{
fast1.Add(fast1.XValues[i - 1] + 0.01, fast1.YValues[i - 1] + r.Next(10) - 4.5);
}
tChart1.Axes.Bottom.Labels.ValueFormat = "";
tChart1.DoubleClick += new EventHandler(tChart1_DoubleClick);
}
void tChart1_DoubleClick(object sender, EventArgs e)
{
Steema.TeeChart.Editor edit1 = new Steema.TeeChart.Editor(tChart1);
edit1.ShowModal();
}
Could you please confirm this is what you've noticed?

Hi Yeray,
yes, I think.
Best regards
