Lazarus has TAChart component for 2D graphs http://wiki.lazarus.freepascal.org/TAChart I've used GLScene for some 3D plotting http://wiki.lazarus.freepascal.org/GLScene You should try the Lazarus mailing list for extra help.

[fpc-pascal] Numerics and graphics in Free Pascal
Hello list, I am new to the list and read it for nearly a week now. So it may be the topic is already answered. In this case, I say sorry. I want to start programming in Free Pascal using Lazarus (installed from the Debian Squeeze) because I want to do programming on my Debian system but I also want use the programs on Windows too. My interests are related to numerics and scientific calculations. There are two things I haven't found in the documentation up to now: 1. is there a library to easy handle matrices or do other numerical calculations like the numpy package does for python? (multiply, solve Ax=b, numerical integration) 2. display graphic representations of data (ploting functions or points in coordinate system, contour plots, 3D plots, etc; example here again my be python multiplot package)? I know there is something like drawing graphic primitives (lines, points, arcs ) which of course can be used to code something. But I don't what to invent the wheel again ;) Thank you for your answers Karsten -- Karsten Rothemund PGP-Key: 0x8D210F3E /"\ Fingerprint: EA42 2654 612F C35B 4030 \ / 4A81 95F0 9FBB 8D21 0F3E \ ASCII Ribbon Campaign wget http://www.photor.de/PHOTOR.ASC / \ Against HTML Mail and News signature.asc Description: Digital signature ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
