[nebula-dev] save as bmp, or tif-fileswt xygraph

["Lars Ohmann" <sohm63@xxxxxx>]

Hello

 

below is the code! It is easy, it just gives a simple plot. How can I save this plot (xygraph) as

a bmp or jpg-file on the PC ? I posted the question on several forums, either the answer is too

complicated or the problem is too trivial for the community.

 

A hint would be very helpful!

 

thanks!
