[matplotlib-devel] matplotlib.text.Text.cached causing problems

[Patrik S. <pat...@ne...>]

Hi there,

matplotlib.text.Text._get_layout(self, renderer) caches
its return value in the dictionary matplotlib.text.Text.cached.
Since it is never emptied, it causes problems when one
creates many figures.

Below, t0.png is ok but t1.png has the vertical tick label 0 in the
wrong place.

import matplotlib
matplotlib.use('Agg')
from matplotlib.matlab import *

y = [[100, 250], [10, 25]]

for i in range(2):
    figure(1)
    bar([0,1], y[i])
    savefig('t%d.png' % i)
    # Uncomment to fix
    #matplotlib.text.Text.cached = {}
    close('all')
