Re: [Matplotlib-users] filled step plot?

[Eduardo B. T. <eeb...@uc...>]

Hi Skipper,

I think you are missing one bin in your plot... but anyway, this is how I'd
do the same plot (filled step plot):


import matplotlib.pyplot as plt
import numpy as np

t_sec = np.arange(6)
velocity = np.array([24., 33., 40., 45., 48., 49.])
width = t_sec[1] - t_sec[0]
plt.bar(t_sec, velocity, width=width, facecolor='b', edgecolor='')
xx = np.ravel(zip(t_sec, t_sec + width))
yy = np.ravel(zip(velocity, velocity))
plt.plot(xx, yy, 'k')
plt.show()

I think this is a bit simpler

Cheers,

Eduardo Banados
