[Matplotlib-users] trouble with pcolor

2012-04-01 Thread David Craig
Hi, I am trying to use pcolor to visualise three variables. For example if I have a value for z at x and a value for z at y something like [x1, x2, x3] = [z1, z2, z3] and [y1, y2, y3] = [z2, z1, z3]. Then I use meshgrid to create the grid for x and y, X, Y = meshgrid(x, y) the result is two

Hi, I wrote an abline_plot function, and I'm curious if what I'm doing is the best way to go about this. I tried unsuccessfully to get the transforms to do what I want, but I'm not sure if it's possible. What I came up with is to use callbacks to draw an infinite line. It works, but it seems a
