Question

Hi probably quite a simple question but..
When plotting a graph using matplotlib.pyplot my Y axis goes from -0.04 to 0.03 which is fine but there are 8 labels for increments (eg 0.03,0.02,0.01 etc.). I need more maybe 16 or so.

Thanks for your help

Answer 1

Use set_yticks() to change the tick locations. For example:

import scipy, pylab
fig = pylab.figure()
ax = fig.add_subplot(1,1,1)
ax.plot(scipy.randn(8))
ax.set_yticks(scipy.arange(-1.5,1.5,0.25))
fig.show()

pylab.yticks() is another option.
