Hi Timo, If you are looking for a one-to-one correspondence between data samples and onscreen pixels, that is a bit tricky. However, fitting the data aspect to the shape of the display window is not as hard. You are not the first person to request such a feature in VisAD, so I added a method setAutoAspect(boolean auto) to DisplayImplJ2D. If you call setAutoAspect(true) on a DisplayImplJ2D object, the aspect will automatically adjust to fit the window every time the display panel changes size. The updated classes should be available on the FTP server within a few days. In the meantime, you can find the two relevant files at http://palm.ssec.wisc.edu/DisplayImplJ2D.java http://palm.ssec.wisc.edu/VisADCanvasJ2D.java Just put these two files in visad/java2d and recompile.
