Hello, I sent an example project to the attachments newsgroup. Another problem with enabling OpenGL. I have a polygon with irregularly shaped upper edge and yellow border. When OpenGL is disabled, the polygon is drawn just fine. That is, polygon surface does not extend past the yellow border. When O...

Active OpenGL breaks gradient

Hello,

I am using TeeChart 7.0.0.5 on Windows XP with Visual Basic 6.

An example project was sent to the attachments newsgroup.

I'm trying to paint a polygon in gradient colors. This works as long as OpenGL.Active is false. When true, gradient has no effect.

FastLine AddRealTime ignores axis limits

Hello, I am using TeeChart 7.0.0.5 with Visual C++ 6.0 and Visual Basic 6 on Windows XP. I sent the example project to the newsgroup. There are two TeeChart controls in the example project. Both use FastLine series. Control on the left demonstrates Series.AddXY(), chart on the right demonstrates pro...

Hello, Very interesting question :-) If there's an answer, I would like to know it too. Locate won't work because it tries to find the exact coordinate, not everything in between. Solution for now could be to have the "realtime source" indicate to database if the point is "good" or not. Then you can...

Ok, now I've stumbled on a problem that requires me to send code :-) I have a chart with one ColorGrid series. I add values dynamically, one row at a time. That project also demonstrates the previous problem of access violation, if mouse hovers over the chart on startup, when the ColorGrid is empty....

First chance Access violation exception

Hello, I am using TeeChart v7.0.0.5 on Windows XP. This problem occurs both in Visual C++ 6 and in Visual Basic 6. I got an Access violation exception that is very easy to reproduce. I am not sending an example project since there's absolutely no code to write. Simply pop in a TeeChart on a form, ad...

Hello Marc, It would be great if such modification was added. I also noticed that the ColorGrid series is basically a Surface series viewed from above. Will this potential change also affect the ColorGrid? I am using ColorGrid series as well. The displayed chart is satisfactory, but I cannot tell ho...

Visual Basic names don't have the "Get" and "Set" prefixes. In VB it's asMap instead of GetAsMap(). So GetShapes() becomes Shapes and GetPolygon() becomes Polygon etc.

Hello, You can add Map series to your TeeChart. Then programmatically add a Polygon to that series. Something like the following: m_PolygonSeries = m_TeeChart.Series(0); m_PolygonMapSeries = m_PolygonSeries.GetAsMap(); // Add a single polygon to the map series. long lPolygonIdx = m_PolygonMapSeries....

Hello Marc, Unfortunately, adding more points to surface to separate colors will not work for me. The number of points that I would have to add can differ from row to row, which is impossible given the NumXValues surface dimension. Going ahead and adding points anyway makes a surface with "holes", a...

Hello, I have a somewhat unrelated visual problem that is also driver/video card related. For now it is fixed by going into Advanced Settings of Display Properties and playing around with "Hardware Acceleration" scale on the Troubleshoot tab.

Hi Marc, Thank you for your help. As you've suggested I will try to produce more points to avoid color interlacing. I tried your solution for "cutting" the surface. Making points transparent hasn't worked. As soon as .Aspect.OpenGL.Active is set to True, all surface parts are visible again. Thank yo...

AxisLabels font color

Clearing the AxisLabels collection or adding labels manually causes the AxisLabels.Font.Color property to fail. After adding labels the AxisLabels.Font.Color property has no effect. I have to go and change Font.Color of each label separately. I sent a sample project to attachments newsgroup. In my s...
