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]
Best regards,
