[Matplotlib-users] beginner help: color map plot from raw data
I'm attempting to plot the distribution of bond angles in protein structures (the best-known example: http://en.wikipedia.org/wiki/Ramachandran_plot). I have the raw data as a collection of x,y,z data, where x and y are integers between -180 and 180, and z is a floating-point value. (Right now, this data is pure Python objects, but I can convert it to NumPy arrays if that would be easier.) I would like to plot this as a continuous color map inside a wxPython window, and also overlay the discreet data points for a separate protein. It doesn't really matter what combination of colors I use for this - there appear to be many built-in color maps that would be suitable. I'm pretty sure this is possible, based on looking at the examples, but I have no clue how to go about this - it doesn't help that all of the examples appear to use the pylab interface. Any suggestions? thanks, Nat -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
[Matplotlib-users] numpy and lapack on linux
I need to distribute matplotlib as part of a large and somewhat heterogeneous package of Python-based software. On Macs, lapack is installed by default, and I can rely on the linking working regardless of which OS version it was compiled on (we use 10.4.11, but it runs fine on 10.5). On Linux, it's variable - the kernel 2.6-based OSes we use appear to have it, but not the older 2.4-based systems. For the older systems this is not a problem - it results in this: n...@linux2.4 ldd lapack_lite.so linux-gate.so.1 = (0xe000) libc.so.6 = /lib/libc.so.6 (0xf7d97000) /lib/ld-linux.so.2 (0x56555000) The lack of links to the full lapack module doesn't appear to break anything that I do - I'm just plotting simple lines and I don't use any of the numpy routines in my code. This is what happens on the newer systems: n...@linux2.6 ldd lapack_lite.so linux-gate.so.1 = (0xe000) liblapack.so.3 = not found libblas.so.3 = not found libg2c.so.0 = /usr/lib/libg2c.so.0 (0xf7fb6000) libm.so.6 = /lib/libm.so.6 (0xf7f8f000) libgcc_s.so.1 = /lib/libgcc_s.so.1 (0xf7f82000) libc.so.6 = /lib/libc.so.6 (0xf7e45000) /lib/ld-linux.so.2 (0x56555000) This results in an import error on systems that *don't* have lapack3 installed. We would prefer to avoid having to tell our users to install more software in order to use what I've written. Is there any way to force numpy to *not* link to anything besides what it saw in the first example? I would prefer to avoid hacking into the numpy distutils scripts if possible. Sorry this isn't directly matplotlib-related, but I thought I'd see if someone here had encountered this problem before I subscribed to another list. thanks, Nat -- Register Now Save for Velocity, the Web Performance Operations Conference from O'Reilly Media.

Unfortunately, this is going to be difficult - our build process is very automated (done every night) and we use these systems for other things too, so I'm very reluctant to tinker with the installed software, and I doubt we have spare boxes with suitable hardware. I will talk to our admin but my guess is he'll say the same thing. thanks, Nat -- Register Now Save for Velocity, the Web Performance Operations Conference from O'Reilly Media.
