Re: Change MarksTip font

Hallo,

thanks for adding it to the request list and also thanks for the example with the annotation.
I've performed a quick test and it seems to work for me!

Thanks,

Re: Change MarksTip font

Hello Sandra,

thanks for the quick response.
I'd like to display a custom text as the tool tip in a table format. In order to achieve this table format I want to use a monospaced font like Courier. That's why I was looking for a way to change the font.

Regards,
Markus

Accessing registry when exporting charts in FLEX format

Hello, we see an "UnauthorizedAccessException" in our application when the FLEX format is chosen in the Export dialog (see attachment). The FlexOptions obviously tries to read and write to the registry key "HKEY_LOCAL_MACHINE\Software\Steema Software\TeeChart.NET". The access to that registry key is...

Re: Background image in Polar

Thanks, Yeray, that worked.
The redrawing really slows down resizing of the control pretty much, but for now, that's ok. At least it's drawn correct.

Re: Drag Point tool with Polar

I implemented it on my own now by using the TChart.MouseDown, MouseMove and MouseUp events and the Polar.PointToAngle() and PointToRadius() methods to convert the X/Y coordinate of the mouse cursor.

Re: Background image in Polar

I found a workaround now and draw the image on my own. In the constructor of the Form, I subscribe to the BeforeDrawValues event of the Polar and in the event handler I draw the image to a clipped region defined by the bounding rectangle of the Polar circle: public Form1() { // ... m_Polar.BeforeDra...

Background image in Polar

Hello, is it possible to have a Polar series with a background image just in the polar circle? I couldn't find any property to set this. It seems that a background image is only available for the whole TeeChart and not just the Polar series. Am I missing something or is this a bug? I'm using TeeChar...

Drag Point tool with Polar

Hi, I'm using TeeChart for .NET 2009 (version 4.0.2009.42283) and try to use the Drag Point tool in a Polar chart. However, it doesn't seem to work properly. When I drag the point horizontally, it actually rotates around the polar circle. Dragging it vertically affects the elevation. Is this a known...

Re: Handle increase - TChart in new thread

Hi Narcis, yes, I did the same without using a separate thread and the handle count did not increase. However, the handle count also increases using a simple .NET Control object instead of a TChart object. So this is a general problem because a Control object could be everything such as a button or ...

Hi, I want to create charts which shall be stored in a database. So the charts are not shown in a UI or something. The chart is periodically created after a specific time span.

Re: Filled Contour plot has empty regions

Hello Narcís, since the Filled Contour Chart is not the right thing for us we use a Color Grid. The actual Color Grid we created looks very nice and would fulfill our requirements. Now here is the but: We wanna use our own palette ranges, so the palette range should go from 0 to 60. The step size is...
