Hi,
I am trying to create an image from an array using PIL, numpy and a
colourmap from matplotlib.
I got the colourmap by using ipython and the following code
colourmap = []
for i in xrange(256):
r,g,b,a = cm.jet(i)
r = int(round((r * 255),0))
g = int(round((g * 255),0))
b = int(

Hi,
I have an ASCII data set, which includes null data points. eg
1 x1 y1 z1
2 x2 y2 z2
3 x3 y3 z3
4 y3 z3
5 y4 z4
6 y5
I am using ipython with pylab enabled, and the load("/xxx/xxx")

Hi,
I am trying to plot an image with matplotlib and change the default axis units.

I'd like to convert them to something else.
