I forgot how we solved this in the end, but it is now working. We store the image as a JPEG, but for a number of users this generates an exception. In this case, the image is saved in bitmap format. We never found out what it is about the small group of users' systems that causes an exception to be ...

Hi Narcis, I think I see what the problem is. If I reduce the size of the graph, then the relative sizes of fonts, line widths etc are not resized. I think the best solution is to first reduce the size of the graphs overall and then also reduce the fonts, lines etc. I have tested this theory with th...

Hi Narcis, I am not sure how this code should look using the StretchDraw method. I would like to use a TJPEGImage object, so that it can be saved to a blob stream. I don't have a direct handle to the printing process as this is done via Crystal Reports, so using code like Printer.Canvas.StretchDraw ...

Thanks for the advice, I will see what I can do and report back.

Hi All, I have a problem printing TChart objects. Here is my situation: I have a C++ project in Borland Developer Studio which uses TCharts. These charts TeeCreateBitmap method is called to extract a bitmap object which is stored in a database for use in Crystal Reports. The chart szies are very lar...

That works a treat! Thanks for the tip.

Thanks for the advice, I will try it this way and let you know how I get on.

Hi all, I have a polar plot with several series, each with several points. These points are joined by lines. The CloseCircle property is switched off, so a line is not drawn between the first and last point. This is desired. What I would like to do is draw a line from the first and last points to th...

Excellent! Thank you very much!

Hi, I need to draw a circle (thick black line) within a polar plot where the diameter of the circle is a point on the left axis. Is there an easy way to do this? I checked out the "tools" options in the TChart editor, but couldn't find anything there. I also thought about setting up a series and the...

I did. I haven't gotten the error message for a few days now, so I don't remember what it was, but like I said I included the Tee header files in my project and that was enough for me, I just wanted to share the tip in case it can help someone out who has tried all the previous steps.

Ok, it works great! Thanks for the help.

Thanks for your swift reply Narcís, I will try this out and will let you know my results.

Hi all, I am fairly new to the TChart components. I created a polar plot based on a set of series already present in our program. The chart used to be a simple line chart. Is there any way to loop through the series of my TChart component and switch them to line or polar plot at will? The client wou...

I also had this same problem, but in the end the only way I could solve the linker errors was to include the .hpp header files directly in my project.
