Re: [Matplotlib-users] axis on top for barh plot
Hi! How can I put the bottom axis on top (or on top AND on bottom) for a barh plot? It's somewhat counter-intuitive, but it can be done. You have to create some twin axes with the twiny option, then make the plot on the twin axes so it will use the top axis. The bottom axis still have to be adjusted manually to make it match the top one and remove the labels. See this example: Thanks for your example. With your help I was able to finally create this with matplotlib, http://www.hep.wisc.edu/cms/comp/cmsprod/diskUserUsage.png and this is my final script, http://www.hep.wisc.edu/cms/comp/cmsprod/plotDiskUse.py One thing that surprised me was to shrink the font for the names required changing ax1 even though the barh plot is on ax2. See these lines: -- ax2.barh(pos, listUse, color=listColors, height=1.0, align='center') ... for tick in ax1.yaxis.get_major_ticks(): tick.label1.set_fontsize(8) -- Surprising.

Thanks for any help, Mike This example might work for your case: http://matplotlib.sourceforge.net/examples/axes_grid/simple_axisline4.html?highlight=subplothost You can disable lower x-axis ticks and labels by using --assuming you will try the example in an ipython -pylab run simple_axisline4.py ax = gca() ax.xaxis.set_major_locator(pylab.NullLocator()) However this disable vertical grids as well. Maybe someone else can point you in the right direction for this.
