Hi, I created a Polygon for MapSeries using Lat/Long and tried to retrieve X,Y positions of vertex to get extent of polygon. And I generated a function as follows. But the X,Y values using GetX() function gave pixel value rather than actual Lat/Long values. It seems that it is possible if I use ITCh...

I am using TeeChart ActiveX v8 in WTL. After instanciating TeeChart, I tried to use mouse to zoom in/out, but nothing happened. So, I set TChart->Zoom->Enable = true, but it did not work. Also for 3D chart, rotating 3D view using mouse did not activate anything. Do I need to add extra mouse events? ...

I would like to specifiy point color as bule. I have used TeeChart VCL and it was 'clBlue' over there. But in ActiveX, I only found 'clTeeColor' and it set color randomly! Any idea to solve this issue?

Thank you
