Well, I finally got it showing in Design mode. However, in runtime, it went from: Screenshot 2024-09-25 125245.png In GDI+ To a flickering black and white window in OpenGL. Is this because there is OpenGL being used in the main executable (remember, this is in a DLL). Screenshot 2024-09-25 130412.pn...

I figured it out. It does not like being on a PageControl's Tabsheet component set to draw Double Buffered.

Unfortunately, my projects have many external references, so I would not be able to send you one. However, you are more than welcome to remote in if you would like. I am in the US Eastern time zone and here from 7:30 - 4:00 most weekdays. I did notice one interesting thing. I made a small DLL projec...

I don't think this would make a difference, but the project is dynamic linked library (DLL), not an executable. I can't see how that would affect the design time, though. It just doesn't work...never has.

Hi Yeray... It is TChart Pro 2023, and RAD Studio (C++) 12.2. However, I have had this issue in previous versions as well. I usually just switch to GDI+, but I need to use lighting for this particular project. And, if I use OpenGL in Tee, then I cannot use it in the project itself. I get all types o...

I am trying to use OpenGL 3D rendering and when I click the Activate button, the whole chart disappears. What am I doing wrong?
Thank you,

Hello,

Is it possible to have the X-axis scale stay the same as the Y-axis, even if zoomed or resized?

Thanks,

John

I don't know why I cannot find any documentation or previous posts about this, but do the xxFloat calls take world or screen coordinates? I tried sending world figuring that was the purpose and the points would be transformed to screen in the call, but it does not seem to be working.

Hello,

Can someone tell me what property I have to change to adjust the heather green color along the left and bottom axes on the attached chart?

Thank you,

John

Here are my includes:

Hello Yerah,

Yes, there is a component on the page already. I set the component's Chart property to the TChart in use and the TChart's drawing setting to 3D OpenGL also.

John

Perfect, thank you!

I attempted to add the component and use it for the chart's canvas. Upon compile, I get about 500 errors like the ones attached. Am I missing an include or something?

Thanks,

John

Hello, thanks for the reply. Yeah, that was a little unclear. What I would like to do is have labels in the chart, not just on the outside axis. For example, running down or across the middle of the chart.

Thank you.

Is there a way to have the labels of an axis show up centered behind (or in front) of the data?
Thanks,
John
