Hello -
I tried to turn of the feature that makes contours with negative values
dashed.
According to the mailinglist this should go by setting: rcParams['
contour.negative_linestyle']=('None','None')
I tried any combination of the None, None syntax, or just 'solid', but
nothing worked.
Example shown below. I am using 0.90.1.
Thanks, Mark
from pylab import *
x,y = meshgrid(linspace(-3,3,10),linspace(-3,3,10))
rcParams['contour.negative_linestyle']=('None','None')
contour(x,y,x,colors='b')
