Hi Yeray,

You are right. The problem is caused by the lib and include path lists. After moving the TeeChart references to the top of the list, it works fine.

Thanks

Hi, I Have just installed the latest version of TeeChart 2010 and C++ Builder XE. When I uses TChart->Canvas->MoveTo() and LineTo() functions to plot a line on the Tchart canvas, it gives an access violation error. The program works fine with previous version. Is this a TeeChart 2010 bug? Regards Xia

Thanks Narcis. It works fine.

Dear Narcis, Thanks for your reply. Sorry, I may not explain that clearly. I have traces displayed on the chart. When I move the mouse to the left side or right side of the chart rect area (outside the chart plotting area) and then press down and hold the left mouse button, I want to scroll the trac...

Hi, I am writing a trace display application using TChart and would like to scroll the trace when pressing and holding the left mouse button outside of the ChartRect, left side to scroll trace to the left and right side to scroll the trace to the right. I have added BottomAxis->SetMinMax() in the mo...

Hi, I have a TChart with over 20 data series added. When I change TeeCommand to 3D display, select the Depth icon and then drag the mouse to resize the 3D, the chart disappears and it can not be recovered. If I rotate the Chart first and then change the depth, it works fine. Also, it only happens wh...

Hi Yeray,

Thanks.

It works and I will recommend to use TChartImageTool when handling a large amount of 2D image data for fast display.

Hi Narcis, Thanks for your reply. I understood that it is a large amount of data points to be processed and TColorGridSeries may not be suitable for a high resolution 2D image (>500x500). Filling data series doesn't take too much time, the main problem is the time to replot the image when resizing t...

Hi, I would like to display over 20 2D images (each has a resolution of 768x560) on the screen using TColorGridSeries. I have tried three methods to speed up data filling and image display 1. Filling data series using a dynamic array; 2. Set series bitmap using Series->Bitmap = aBitmap 3. Set BackIm...

Hi Yeary,

Thanks. It works.

Regarding the grid on/off bug for TColorGridSeries, will this be fixed in next 3-6 months? If not, do you have a work-around solution?

Regards

Hi Narcis, Thanks for your reply. I have already set IrregularGrid=false. TColorGridSeries is very powerful data series for 2D image display and it is just a bit slow for a higher resolution image. For the TDrawLineTool, I would like to handle differently when dragging the entire rectangle for repos...

Hi Yeary, Thanks. You are right that I need to change the include and lib paths to new version. TDrawLineTools synchronisation works nicely for two TCharts. A drawback of this synchronisation when dragging the rectangle is that it is a bit slow for TColorGridSeries when having over 500x500 pixels. H...

Hi Yeary, Thanks for the example files. It has the same problems with TChart V8.02. But after upgrading to TChart V8.06, the program works fine, i.e. both Rectangles can be resized at the same time. So I think the problem is related to TChart V8.02. However, I have two other projects which worked fi...

Hi Yeary, Thanks for the application code. I have created a project using your code, but I have to change accordingly since I am using CodeGear C++ Builder. I have the same problems. 1. When you resize the rectangle on the Chart1 by dragging the corner of the rectangle, the rectangle on the Chart2 d...

Hi Yeray, I have already added the OnMouseDown event at design time. If I understand correctly, the OnDragLine event is only called at the beginning of dragging (i.e when pressing the mouse down) and it will not response to mouse move with the left button pressed for resizing the rectangle.
