Hi all,
I'm trying to visualize some data using countourf in pyplot, and I am having
a bit of trouble. For some reason, the y axis does not scale properly, and
an ugly white bar appears where there are no pixels to plot (see
screenshot). Ideally, I would like the axes to scale so that there is no
white space. The script I am using is:
q=1.60219e-19
kGrid = linspace(0.01,25e7,100)
epsGrid = linspace(1e-10*q,0.13e-3*q,100)
X,Y = meshgrid(kGrid,epsGrid)
Z = abs(integrand(X,Y))
CS = plt.contourf(X,Y/q/1000,Z,100,cmap=cm.PRGn)
Here, "integrand" is just some function that generates z values. I imagine
that it is something with aspect ratios or scaling, but I haven't been able
to figure it out from reading posts, so I would greatly appreciate some
guidance!
Many thanks,
John
