I am attempting to rotate the x labels of a subplot (created using GridSpec) by 45 degrees. I have tried using axa.set_xticks() and axa.set_xticklabels, but it does not seem to work. Google wasn't helping either, since most questions concerning labels are about normal plots, and not subplots.
See code below:
width = 20 # Width of the figure in centimeters
height = 15 # Height of the figure in centimeters
w = width * 0.393701 # Conversion to inches
h = height * 0.393701 # Conversion to inches
f1 = plt.figure(figsize=[w,h])
gs = gridspec.GridSpec(1, 7, width_ratios = [1.5, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0])
axa = plt.subplot(gs[0])
axa.plot(dts, z,'k', alpha=0.75, lw=0.25)
#axa.set_title('...')
axa.set_ylabel('TVDSS ' + '$[m]$', fontsize = '10' )
axa.set_xlabel('slowness 'r'$[\mu s/m]$', fontsize = '10')
axa.set_ylim(245, 260)
axa.set_xlim(650, 700)
axa.tick_params(labelsize=7)
axa.invert_yaxis()
axa.grid()
Any help will be greatly appreciated!
You can set the rotation property of the tick labels with this line:
plt.setp(axa.xaxis.get_majorticklabels(), rotation=45)
setp is a utility function to set a property of multiple artists (all ticklabels in this case).
BTW: There is no difference between a 'normal' and a subplot in matplotlib. Both are just Axes objects. The only difference is the size and position and the number of them in the same figure.
