Hi Jeff, you can do something like the following and specify the color for each bar by providing a list of colors for the keyword argument 'color'.
import numpy as np import matplotlib.pyplot as plt # generate some data left = np.arange(6) height = np.random.uniform(size=6) # plot 3 blue and 3 red bars: plt.bar(left, height, color=['blue']*3+ ['red']*3) plt.show() You second way could be provided by the color list ['red', '0.5']*3 = ['red', '0.5', 'red', '0.5', 'red', '0.5'] Kind regards, Matthias On Saturday 23 January 2010 16:36:36 Jeff Layton wrote: > Good morning, > > I hate to ask such a newbie question but I am a newb with matplotlib :) > > I want to create a bar chart with, for example, 6 "bars".
