Re: [Matplotlib-users] Setting the tick label font size
Daniele,
I agree this is perhaps a little overly complicated. (However, once you
figure it out, it does give you a ton of flexibility.) I played around
with this a bit (thanks IPython!), and I may have figured out what you
wanted to do. I rewrote the example you linked from the MPL website. I
couldn't simplify it much, but it does change the size, location and labels
of the floating y axis.

from mpl_toolkits.axes_grid1 import host_subplot
import mpl_toolkits.axisartist as AA
import matplotlib.pyplot as plt
host = host_subplot(111, axes_class=AA.Axes)
plt.subplots_adjust(right=0.75)
par1 = host.twinx()
par2 = host.twinx()
offset = 60
new_fixed_axis = par2.get_grid_helper().new_fixed_axis
par2.axis["right"] = new_fixed_axis(loc="right",
axes=par2,
offset=(offset, 0))
par2.axis["right"].toggle(all=True)
p1, = host.plot([0, 1, 2], [0, 1, 2], label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2], label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], label="Velocity")
host.legend()
host.set_xlabel("Distance")
host.set_ylabel("Density")
host.axis["left"].label.set_color(p1.get_color())
host.set_xlim(0, 2)
host.set_ylim(0, 2)

par1.axis["right"].label.set_color(p2.get_color())
par1.set_ylim(0, 4)
par2.set_ylabel("Velocity")
par2.set_ylim(1, 65)
par2.yaxis.set_ticks( (20.0, 40.0) )
par2.yaxis.set_ticklabels( ('A', 'B') )
par2.axis["right"].label.set_color(p3.get_color())
par2.axis["right"].label.set_fontsize(18)
par2.axis["right"].major_ticklabels.set_fontsize(14)

Hope that helps.

Hello Ryan, thanks for confirming the problem. I've also seen that note, but I thought "do not work" means that the methods raise an exception, not that they arbitrarily ignore arguments :( While the standard Axis class works for the cut-down example I posted, it does not for what I'm trying to achieve (having a second x axis below the main one). I came up with that solution following the matplotlib documentation: http://matplotlib.org/mpl_toolkits/axes_grid/users/overview.html#axisartist-with-parasiteaxes however I don't really understand why some of the contortions there are necessary (they are not explained in the documentation).

Re: [Matplotlib-users] Setting the tick label font size
Daniele, I noticed the same problem with the Qt backend. However, I was looking at the documentation on the AxesGrid webpage here: http://matplotlib.org/mpl_toolkits/axes_grid/users/overview.html And I see the following warning: axes_grid and axisartist (but not axes_grid1) uses a custom Axes class (derived from the mpl’s original Axes class). As a side effect, some commands (mostly tick-related) do not work. Use axes_grid1 to avoid this, or see how things are different in axes_grid and axisartist (LINK needed) Unfortunately, no link. But perhaps there is a way to avoid using the Axes class from axisartist in your use case. For example, could you import the Axes class as follows: from matplotlib.axes import Axes That seems to work with the Qt and PDF backends on Windows 7 (Anaconda Python).

Hello, it investigated this a bit further and the problem presents itself only when I use `mpl_toolkits.axisartist.Axes`. Here is a minimum example that demonstrates the problem: import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.axes_grid1 import host_subplot from mpl_toolkits.axisartist import Axes x = np.linspace(0, 2*np.pi) y = np.sin(x) f = plt.figure() BUG = True if BUG: ax1 = host_subplot(111, axes_class=Axes) else: ax1 = host_subplot(111, axes_class=Axes) ax1.plot(x, y) ax1.set_xlim(0, 2*np.pi) ax1.set_xticks(np.linspace(0, 2*np.pi, 5)) ax1.set_xticklabels(['%.2f' % x for x in np.linspace(0, 2*np.pi, 5)], fontsize=8) plt.draw() plt.show() Cheers, Daniele -- Android is increasing in popularity, but the open development platform that developers love is also attractive to malware creators.

Hi Daniele, not sure, but it seems to work for me. Did you do a plt.draw() or plt.show() to reflect the changes?
