I have recently drawn up a lot of plots in Python (matplotlib), but then I realized that I couldn't find their LaTeX equivalents.
I am specifically looking to generate circle, square, and diamond symbols which are half-filled (left, right, top or bottom).
For example I can generate filled and unfilled squares using \backsquare and \Square but cannot generate a partially filled one (filled left-, right-, top- half etc). I can do that for left- and right filled circles using \LEFTcircle and \RIGHTcircle but not for other symbols.
sagetexpackage lets you work with matplotlib. See my answer to Contour plot of arbitrary R^3 function without gnuplot. – DJP May 28 '15 at 19:12
