Re: [Matplotlib-users] hide labels

[Francesco M. <fra...@go...>]

Dear all again,

I've tried to play with it again, but I couldn't find a solution for
the problem.
For clarity I report an example of what each of the subplots looks like:

> import numpy as np
> import matplotlib.pyplot as plt
> mean = np.array([-0.9206394,  -0.90127456, -0.91983625, -0.97765539, -1.02991184, -1.02267017, -0.97730167, -0.93715172, -0.94324653, -0.92884379])
> stddev = np.array([0.16351397, 0.15075966,  0.13413909,  0.15404823,  0.13559582,  0.13109754,  0.12128598,  0.11589682,  0.11921571,  0.10866761])
>
> ax = plt.figure().add_axes([0.1,0.1,0.8,0.8])
> ax.errorbar(np.arange(10,20)/100., mean, yerr=stddev)
>
> ax.set_xlim([0.095, 0.195])
> lab = ax.get_ymajorticklabels()
>
> print lab
> for i in lab:
>  print i
>
> plt.show()

as output of this script I get
> <a list of 7 Text yticklabel objects>
> Text(0,0,'')
> Text(0,0,'')
> Text(0,0,'')
> Text(0,0,'')
> Text(0,0,'')
> Text(0,0,'')
> Text(0,0,'')
In the plot instead I only have only 5 y tick labels, as visible from
the attachment. In this case if I set the first and the last label
invisible, nothing changes, and if I have other plots under this the
plot becomes ugly/unreadable.

I hope to have been clearer than in my previous mail.
Any suggestion on how to fix or find a workaround in order to get the
same number of tick labels as the ones actually plotted.

Thank in advance
Fra
