[Matplotlib-users] Pie Charts, How to control pie chart size in figure?
Hi, I am making a simple pie chart that needs to be small ~3x3 inches.
The problem I am having is that the text labels get pushed out side the
figure. Is there anyway to make the plot smaller relative to the figure
size? Here is my code and the resulting plot:
from pylab import *
# make a square figure and axes
figure(1, figsize=(3,3))
ax = axes([0.0, 0.0, 1.0, 0.9])
labels = 'Central\nCampus','Medical\nCampus','North\nCampus'
fracs = [880,220,1000]
explode=(0.05, 0.05, 0.05)
ppl=pie(fracs, explode=explode, labels=labels, shadow=True,autopct='%1.0f%%')
title('GSRAs by Campus')

[Matplotlib-users] Is there an easy way to turn on automatic subticks?
I am making regular Cartesian coordinate graphs with linear scales on the axis. I would really like to have automatic subticks to make reading data easier. Is there an easy way to do this?

Yes, you just need to set a locator for the minor ticks, which is set to NullLocator by default. import matplotlib.pyplot as plt from matplotlib.ticker import MaxNLocator plt.plot([1,2,3]) ax = plt.gca() ax.xaxis.set_minor_locator(MaxNLocator(nbins=30, steps=[1, 2, 5, 10])) plt.show() You might also want to look at: http://matplotlib.sourceforge.net/examples/pylab_examples/major_minor_demo1.html?highlight=codex%20minor Ryan That does it!
