Hi, I have a plot of a time series and I would like to add a single extra tick mark and label to the plot in a different color to the already existing tick marks. Is this possible??
Thanks,
D
It’s fairly easy to do if you want to set the tick locations and labels youself (see http://matplotlib.sourceforge.net/users/artists.html near the end for an overview of the mpl containers like Tick and the attributes they contain).
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots(1)
ax.plot(np.random.randn(10,2)*10)
locs = np.arange(2, 10, 2)
labels = [‘%d’%loc for loc in locs]
ticks, labels = plt.xticks(locs, labels)
i = 2
tick1line and tick2line are matplotlib.lines.Line2D instances
ticks[i].tick1line.set_color(‘red’)
ticks[i].tick2line.set_color(‘red’)
labels[i].set_color(‘red’)
plt.show()
If you want to “add a tick” using the existing mpl auto tick locating and labeling infrastructure, it is also possible but you will need to subclass the tick locator.
