How to plot non-numeric data in Matplotlib
I want to plot the time variation of a y-axis variable using Matplotlib. This is not a problem for continuous discrete data, but how it should be addressed for non-continuous data.
those. if I wanted to visualize the times in which my car was on the way to work, the x-axis would be time and the y-axis would be made up of the variables "stationary" and "moving" (pretty useless example that I know)
Continuous data needs to be indexed somehow, but I don't know how to proceed ... any ideas?

Is this the type of thing you want? (If not, you can check the matplotlib gallery page to give yourself some ideas or just draw a picture and post it.)
import matplotlib.pyplot as plt
data = [0]*5 + [1]*10 + [0]*3 +[1]*2
print data
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(data)
ax.set_yticks((0, 1.))
ax.set_yticklabels(('stopped', 'moving'))
ax.set_ybound((-.2, 1.2))
ax.set_xlabel("time (minutes)")
plt.show()
