I know about plot_date() but is there a bar_date() out there? The general method would be to use set_xticks and set_xticklabels, but I'd like something that can handle time scales from a few hours out to a few years (this means involving the major and minor ticks to make things readable). I am plotting values associated with a specific time interval (that the bar spans). Here is the basic solution I used: import matplotlib.pyplot as plt import datetime t = [datetime.datetime(2010, 12, 2, 22, 0), datetime.datetime(2010, 12, 2, 23, 0), datetime.datetime(2010, 12, 10, 0, 0), datetime.datetime(2010, 12, 10, 6, 0)] y = [4, 6, 9, 3] interval = 1.0 / 24.0 #1hr intervals, but maplotlib dates have base of 1 day ax = plt.subplot(111) ax.bar(t, y, width=interval) ax.xaxis_date() plt.show() Continue reading...
