They rely on patch of course. I see now way to do this with gnuplot. To the best of my knowledge, nothing even approximating patch is not even planned for gnuplotI think patch is possible with gnuplot. What I meant is that all of these should wait for patch to be implemented in octave core before doing much with them.. If you have something working in octplot, perhaps you can suggest patches to the core to and least get the front-end of patch objects included in the core..
Hello David,are you sure that gnuplot supports patches? What I have learned from the website is that gnuplot supports arbitrary shaped rectangles and has some fill options for line plots ..., but polygons? Can you give me a pointer what you have in mind?
The contourf function in octplot (or in general) needs patch objects of arbitrary shape. This includes concave polygons, the octplot implementation uses the OpenGL utilities lib (GLU) for polygon tesselation and plotting.
