Hi,
I'm trying to plot some horizontal bars using the .bar() method:
import matplotlib.pyplot as plt
fig=plt.figure()
ax=fig.add_subplot(1,1,1)
ax.bar([1,2,3],[4,6,5],orientation='horizontal')
raises an AssertionError:
AssertionError Traceback (most recent call last)
/home/ernest/<ipython console> in <module>()
/usr/lib/pymodules/python2.5/matplotlib/axes.py in bar(self, left, height, width, bottom, color, edgecolor, linewidth, yerr, xerr, ecolor, capsize, align, orientation, log, **kwargs)
4230 # FIXME: convert the following to proper input validation
4231 # raising ValueError; don't use assert for this.
-> 4232 assert len(left)==nbars, "incompatible sizes: argument 'left' must be length %d or scalar" % nbars
4233 assert len(height)==nbars, ("incompatible sizes: argument 'height' must be length %d or scalar" %
4234 nbars)
AssertionError: incompatible sizes: argument 'left' must be length 1 or scalar
using scalars doesn't help:
ax.bar(1,5,orientation='horizontal')
TypeError: unsupported operand type(s) for +: 'NoneType' and 'int'
Am I doing something wrong??
