Given this 3D bar graph sample code , how would you convert the numerical data in the x-axis to formatted date/time strings? I've attempted using the ax.xaxis_date() function without success. I also tried using plot_date(), which doesn't appear to work for 3D bar graphs. Here is a modified version of the sample code to illustrate what I am trying to do: from mpl_toolkits.mplot3d import Axes3D import matplotlib.pyplot as plt import numpy as np import matplotlib.dates as dates dates = [dates.date2num(datetime.datetime(2009,3,12)), dates.date2num(datetime.datetime(2009,6,9)), dates.date2num(datetime.datetime(2010,1,1)), #etc... ] fig = plt.figure() ax = Axes3D(fig) for c, z in zip(['r', 'g', 'b', 'y'], [30, 20, 10, 0]): xs = np.array(dates) ys = np.random.rand(20) ax.bar(xs, ys, zs=z, zdir='y', color=c, alpha=0.8) ax.set_xlabel('Date & Time') ax.set_ylabel('Series') ax.set_zlabel('Amount') plt.show()
