Hi:
I want to add a legend to a stem plot with two plots. The basic code is:
###########################
from pylab import *
x = [1,2,3,4,5]
y1 = [1, 2, 3, 4, 5]
y2 = [5, 4, 3, 2, 1]
subplot(211)
plot(x, y1, 'rx-')
plot(x, y2, 'bx-')
legend(('a', 'b'))
subplot(212)
stem(x, y1, 'r')
stem(x,y2, 'b')
legend(('a', 'b'))
show()
###########################
The left subplot is the same plot using plot instead of stem. You can
see the result here: http://imagebin.org/128376 .
I expect the legend for the stem case to look similar to the plot
case, however, for the stem, I get the two labels of the legend
associated with the first stem command: 'a' linked to the marker and
'b' linked to the stem line.
Is there any way to fix this? Is this a bug?
Alejandro.
