Hi everyone,
I wonder if there is a simple way to apply a multiplication factor to
the ticks labels of an axis.
say I'm plotting a 100 x 100 matrix with imshow and want the axis to
show (0 to 70) instead of (0 to 100), while still displaying the whole
matrix. In that case the coefficient would be 0.7.
I had a look at the Formatter class but I cannot find a method to do
that, do I've to implement a custom formatter or I'm missing something
obvious here ?
many thanks
Henry
Use the "extent" keyword argument to imshow to set the [xmin, xmax,
ymin, ymax] extent of the image
