Hi again, sorry for multi-posting.

Apparently, figure.tight_layout() does not take into account the secondary
y-axis on the right.

Is this a known limitation ? (I don't see it on the caveats paragraph [1].)

Or is this the use I make of it that is incorrect ?

Example :

--------------------------------------------------------------------------

import pylab

fig = pylab.figure()

data_1 = [0,1,2,3]
data_2 = [0,5,250,30000]

lines = []

# Primary axis
ax1 = fig.add_subplot(1,1,1)
lines.extend (ax1.plot(data_1, 'b'))

# Secondary axis
ax2 = pylab.twinx(ax1)
lines.extend (ax2.plot(data_2, 'g'))

labels = ['Data 1', 'Data 2']

fig.tight_layout()

pylab.show()


--------------------------------------------------------------------------

Thanks.
