Please consider:
plot([1, 2, 3, 4], label='line 1')
twinx()
plot([11, 12, 11, 14], label='line 2')
legend()
will draw only label for 'line 2'
plot([1, 2, 3, 4], label='line 1')
legend()
twinx()
plot([11, 12, 11, 14], label='line 2')
legend()
same result, as it will overwrite label 'line 1' with label 'line 2'
How to deal with this, without manually positioning legends and if
possible including all annotated plot lines in one legend?
Thanks
I would do something like
from matplotlib import pylab
LegendText = []
pylab.twinx() # << had to move before first plot else it blew up
pylab.plot([1, 2, 3, 4] )
LegendText.append('line 1')
pylab.plot([11, 12, 11, 14])
LegendText.append('line 2')
pylab.legend( LegendText , loc='lower right')
pylab.show()
Don't know if there is a better way
