Dear Nils,
I think that I've found what you need (example adapted from
http://notes.brooks.nu/2008/03/plotting-on-left-and-right-axis-simulateously-using-matplotlib-and-numpy/
)
import matplotlib.pyplot as plt
import numpy as np
#data to plot
x = np.linspace(0,5,num=100)
y = np.sinc(x)
fig = plt.figure(figsize=(16,10)) #figure
ax= fig.add_subplot(111)#axis containing the figure
ax1 = fig.add_subplot(111, sharex=ax, sharey=ax, frameon=False)
#axis that shares both x and y and without frame (so ax is visible)
ax.plot(x, y) #plot the data
ax1.xaxis.tick_top() #show ticks on top
ax1.yaxis.tick_right() #show ticks on the right
Now if you do any modification on the ax limits should reflect on ax1.
Might be that there is some smarter way of doing it, but if the
project is not too long and efficiency is not a problem, I think that
this example will suffice
Cheers,
Francesco

Dear Francesco,
Thank you for your prompt reply !
My incomplete example is below.
import matplotlib.pyplot as plt
fig = plt.figure(figsize=(16,10))
ax = fig.add_subplot(111)
ind = np.arange(nfreq)
yoff = np.array([0.0]*nfreq)
for row in range(nsets):
ax.bar(ind,A[row,:],width,bottom=yoff,
color=colours[row],label=elabel[row])
yoff = yoff + A[row,:]
plt.legend(loc=upper left, bbox_to_anchor=(1,1))
plt.xticks(ind+0.5*width,np.arange(nfreq)+1,rotation=90)
ax.set_xlim(0.,nfreq)
ax.set_ylim(0.,102.)
plt.subplots_adjust(left=0.075, right=0.85, top=0.9, bottom=0.05)
plt.show()
How can I add xtick labels on the top of my figure ?
Cheers,
Nils

Dear Nils,
you can try to play with
i) ax.axis[right, top, bottom, left] and their methods (see
setup_axis3 here
http://matplotlib.sourceforge.net/examples/axes_grid/demo_floating_axes.html
for an example)
ii) twinx and twiny axes (example
http://matplotlib.sourceforge.net/examples/api/two_scales.html )
The first one can be a bit confusing with orientations. Once I found
an explanation about it on matplotlib website, but I cannot find it
right now.
The second way creates a second axis that you probably don't need.
Cheers,
Francesco

Hi all,
I would like to add different xtick labels on the top and
bottom of a figure. The number and position of the xticks
is the same.
How can I do that ?
An example would be appreciated.
Nils
