[Matplotlib-users] Using strings as units for the x-axis

[Florian L. <Flo...@xg...>]

Hello,
can I use strings as units for the x-axis. Like plot([1,2,3],['A','B','C']).
Of course, for every line the second argument must be the same.
Is that possible?

Thx,
Florian

The way to get strings along the xaxis is to use the xticks function if you 
are using the pylab interface.
plot([1,2,3])
xticks([0,1,2],['A','B','C'])

 or you can use the axes xaxis.set_ticks and xaxis.set_ticklabels:
ax=axes()
plot([0,1,2])
ax.xaxis.set_ticks([0,1,2])
ax.xaxis.set_ticklabels(['A','B','C'])
draw()


Are you familiar with the examples? 
http://matplotlib.sourceforge.net/matplotlib_examples_0.80.zip
You might not think to look there in barchart_demo.py, but it explains this 
procedure.

Hope this helps,
Darren
