Hi Neil,
I've been using the new plot library for visualizing some benchmark
results in three dimensions (# threads, amount of work, throughput).
It's very easy to use, and the interactive 3d plots are great. I also
plan to use the PDF export for my next paper. Thanks for making this
available!
You're welcome!
My evil master plan is to beat R and come close to Mathematica, to
remove one more reason for statisticians and other applied
mathematicians to use something other than Racket. I'm going after the
statisticians first, though.
My only request: a version of surface3d that takes as input a list of
discrete points. I find the surface visualization more useful than a
scatter plot, but I've had to code my own interpolation to make it
work. I'm guessing surface3d is already doing its own interpolation
(and of course sampling) so coding my own seems redundant.
I'll put something like that on my to-do list. As it is, 'surface3d'
only appears to interpolate bilinearly because it uses sampled x,y,z
coordinates as quad vertexes. But I don't think it would be hard to make
it do bilinear interpolation for non-grid x,y coordinates, to come up
with z values for grid x,y coordinates.
(Oh, hang on. The contour line endpoints are interpolated - it's part of
the marching squares algorithm - so there's that.)
FWIW, the latest update I pushed added contracts to all the 2D plot
functions and parameters, and some incomplete documentation for them.
(Run "build.sh" in the "scribblings" directory. Check out the quick
start.) It also minimizes the margins on 3D plots, does better depth
sorting, and handles NaNs and Infs, which you'll probably appreciate. I
think the only major change it would impose on you is replacing 'mix'
and 'mix3d' with 'list'.
