bar plot errorbars

Hi,

Is there a way to have errorbars in a bar plot going in just one
direction? E. g. like that

···

instead of

   -

   -

?

TIA

It seems that this is not possible with bar or barh.
I guess the best way is to use a separate errorbar comannd

import matplotlib.pyplot as plt
import numpy as np

val = 3+10*np.random.rand(5) # the bar lengths
pos = np.arange(5)+.5 # the bar centers on the y axis
yerr = np.random.rand(5)
plt.figure(2)
plt.bar(pos,val, align='center')
erb = plt.errorbar(pos, val, yerr=[np.zeros(len(yerr)), yerr], fmt=None)
erb[1][0].set_visible(False) # make lower error cap invisible
plt.xticks(pos, ('Tom', 'Dick', 'Harry', 'Slim', 'Jim'))

plt.show()
