Hello,
I have a contour with a clim smaller than the limits of my data... and because of this there is an error when I try to add a colorbar.
Can someone help?
Thanks
MMA
eg:
x=arange(20)
y=arange(30)
x,y=meshgrid(x,y)
v=sqrt(x+y) # max=6.928, min=0.0
# next is ok
figure()
contour(x,y,v)
clim(0,7)
colorbar()
# next gives the error: "ValueError: levels are outside colorbar range"
figure()
contour(x,y,v)
clim(2,6)
colorbar()

I think the basic problem is that you are trying to use a colorbar as a legend in a case where it doesn't really makes sense; the colorbar is mapping a range of values to a range of colors, and you have values that are outside that range. There are a couple ways to fix the problem:
1) Try using "colorbar(extend='both')". This is a workaround, but it may do what you want.
2) Explicitly specify a list of contour levels that are within the range of your clim. This is a better solution.
