matplotlib-users Mailing List for matplotlib

Hi,
I'm trying to draw a bar chart according to
http://matplotlib.sourceforge.net/examples/api/barchart_demo.html, and I'm
having to difficulties :
 - when the first bar has a zero height, it is no taken into account during
the axis limits calculation and is not visible
 - texts objects can exceed chart area and collide with the chart title.
Is there a way to calculate the axis limit to use to include all texts
objects into the chart area ?
Here is the code I used :
[code]
#!/usr/bin/env python
import numpy as np
import matplotlib.pyplot as plt
menMeans = [ 0. , 998. , 1210. , 1449. ,
 1496. , 1493. , 1593.40002441, 1517.5 ]
ind = np.arange(len(menMeans)) # the x locations for the groups
width = 0.8 # the width of the bars
fig = plt.figure()
ax = fig.add_subplot(111)
rects1 = ax.bar(ind, menMeans, width, color='r')
# add some
ax.set_ylabel('Scores')
ax.set_title('A very very long title for testing.')
def autolabel(rects):
 # attach some text labels
 for rect in rects:
 height = rect.get_height()
 ax.text(rect.get_x()+rect.get_width()/2., 1.05*height,
'%d'%int(height),
 ha='center', va='bottom')
autolabel(rects1)
plt.show()
[/code]

No, the numpy installers have never had a problem on 10.4 AFAIK. The
issue was that installers built on 10.6 would (on some but not all
machines) fail on 10.5.

This is just a file name, not necessarily the cause of any error
during installation.
