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?? -- Ernest ------------------------------------------------------------------------------ Come build with us!
