Histogram issue

Hi
I’ve found an issue with the HorizHistogram series. I need to use the series with inverted axis.
When you invert the horizontal axis it appears unfilled, when you invert the vertical axis it raise an exception.
I've also had problems with horizontal areas with stairs.
Could you help me with this?
I'm using TeeChart 2.0.3203.23272
Thanks in advance!

Hi Ricardo,
When you invert the horizontal axis it appears unfilled
I could reproduce this issue here and added it (TF02013446) to the defect list to be fixed for next releases. In the meantime, the only solution I can think of is hidding series pen lines:
Code: Select all
histogram1.LinesPen.Visible = false;
histogram1.LinePen.Visible = false;
when you invert the vertical axis it raise an exception.
I'm not able to reproduce this here. Could you please send us a simple example project or a code snippet we can run "as-is" to reproduce the problem here?
You can post your files at news://
www.steema.net/steema.public.attachments newsgroup or at our
upload page.
I've also had problems with horizontal areas with stairs.
I'm not able to reproduce the same issue with HorizArea series. Which are the exact problems you had with this series style?
Thanks in advance.

I've posted an image named Histogram.jpg in the upload page.
There you can see the exception that I received when I've assigned the inverted property to the vertical axis with the histogram series in design time without any line of code written, I've just changed the property value in the property inspector.
For more information, I have windows Vista and Visual Studio 2005 SP1

I'm sorry, I forgotten the other question that you asked regarding the area series. The problem is the same with horizHistogram with inverted horizontal axis, the series appears unfilled when you set the stairs property to the series and the inverted property to the horizontal axis. Without the stairs property it works fine.

I've finally been able to reproduce the issue here. I didn't notice it was using HorizHistogram, I originally used Histogram series. I also added this bug (TF02013451) to the defect list to be fixed for next releases.

Ok, that didn't happen for me here using HorizHistogram and Histogram but I'm able to reproduce this with HorizArea series. I've added the defect (TF02013452) to the bug list to be fixed for next releases.

Hi, I have read the release notes of the last release of TChart 3, and there I found fixed the issues reported in the previous posts above, I mean…
6) [TF02013451]
Histogram and HorizHistogram series not
rendering correctly when the axis
associated with the YValues is inverted.
Fixed.
7) [TF02013446]
Histogram and HorizHistogram series not
rendering correctly when the axis
associated with the XValues is inverted.
Fixed.
[TF02013452]
Area and HorizArea series not rendering
correctly with the axis associated
with the YValues inverted and Stairs
set to true. Fixed.
Do you have any idea when will you fix this problems in version 2?
Thanks a lot
