contourf shows a unwanted white space

Friends,

I used contourf function to plot a matrix, the output figure is attached. In the figure, i observe a strange white space at the corners. What is going wrong here. Herewith i have also attached the code.

Also someone please explaing me the usage of locator and x,y units **kargs available for contourf function.

Thanks,
Bala

Bala,

the white space you see is due to contourf trying to have the axes ticks end on a round number. If you don’t want that behavior, you can set the limits of the plot after calling contourf() with something like this:

contourf(X, Y, Z)
xlim(x_min, x_max)
ylim(y_min, y_max)

presuming you would know which values to use for the min and max variables.

Somebody else will have to explain the locator and the x,y units kargs because I am not familiar with them.
