I am trying to animate a text box in a Matplotlib figure, but can't seem to get it working. Does anyone know how to do this properly? An example is below.
from matplotlib import animation import matplotlib.pyplot as plt import numpy as np from mpl_toolkits.basemap import Basemap fig = plt.figure() ax = fig.add_subplot(111) times = ['first', 'second', 'third'] time_text = ax.text(.5, .5, '', fontsize=15) def updatefig(num): global mt mt = ax.text(.5, .5, times[num], fontsize=15) anim = animation.FuncAnimation(fig, updatefig, frames=len(times)-1, blit=True, init_func=init)

Will.Evo over 4 yearsI know this is old, but how do you also update the location of the text on the graph?

R Kiselev over 4 yearsI would assume you use something like
time_text.set_x(x[num])
andtime_text.set_y(y[num])
