[Matplotlib-users] Continuously varying line colors?
I'm hoping to generate a line plot where the color of each pixel on the plot is given by linearly interpolating the colormap from each point specified in the line, instead of having the whole line be a solid color. I can "mock this up" by doing a scatter plot where the points are much closer together than the screen resolution, but that seems inelegant, and sometimes produces weird output. So is there a way to do effectively the same thing with a line plot or somehow specify this behavior in scatter? -- Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.

[Matplotlib-users] I need all value on X(hours, minutes) label

IIRC, the backends that matplotlib uses (Gtk, Agg, etc.) only support a single color per line, so breaking up the line into different segments/points is really your only option. Instead of scatter, you can break up your line into separate sections and have them colormapped for you, using a LineCollection.

[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.
