Space not wanted between 2 sigma contours and surface of these contours

Hello,

I am faced to a strange behavior. Using :

Code: Select all

g.triangle_plot([matrix1, matrix2],
names,
filled = True,
legend_labels = [],
contour_colors = ['darkblue','red'],
line_args = [{'lw':2, 'color':'darkblue'},
{'lw':2, 'color':'red'}]
)
If I zoom much larger, I get the following 2 sigma contours (blue) and light blue surface associated to this 2 sigma :

If you look at better, you can see that I get the same issue for 1 sigma red contours and light red surface associated.

From you, what is the cause of this slight shift between areas and effective contours ( 1 sigma and 2 sigma) ? I expected to have the contours lines surrounding perfectly the surfaces.

Regards
