Thread: [Matplotlib-users] Try to have none-overlapping labels in one axe using matshow

Not sure this message was sent successfully. So I send it again. Sorry if you
receive it twice...

Hello,

This question has certainly been answered in a previous thread but after
searching around I did not find any solution...

I have got a matrix 6x500 (so one size is much biggger than the other one)
and I try to expand the shorter axe so that the labels on it are well
displayed (not overlapped.

I am googling/searching on the documentation about subplots_adjust, ... but
did not find any solution.

Here is the code that present the problem I have.

Thanks in advance for any help.  Olivier

import numpy as np
from matplotlib.pylab import *
import matplotlib.pyplot as plt

sizeX = 6
sizeY = 500

xlabels = []
ylabels = []

for i in range ( 0, sizeX ):
  xlabels.append( str( i ) )

for i in range ( 0, sizeY ):
  ylabels.append( str( i ) )

dims = ( sizeX, sizeY )

data = zeros( dims )
for i in range( 0, sizeX ):
  for j in range( 0, sizeY ):
    data[ i, j ] = np.random.rand()

figure = plt.figure()
axes = figure.add_subplot( 111 )
cax = axes.matshow( data, interpolation = 'nearest' )
col = figure.colorbar( cax )

plt.show()

Use the aspect kwarg in matshow.

Goyo

Indeed setting aspect = 'auto' in matshow solved my problem.

Thanks a lot !
