### Plot only 1 sigma or 2 sigma contours

Posted:

**August 01 2020**Hello,

In a context of covariane matrix with Fisher's formism, I would like to plot, with

Here is below my current code snippet that plots 1 and 2 sigma at the same time of 2 covariance matrixes (matrix1 and matrix 2) :

I saw during my researches a paramater called

in

If anyone could help, this would be fine.

In a context of covariane matrix with Fisher's formism, I would like to plot, with

**triangle_plot**function only 1 sigma contour or 2 sigma contours, not the both in the same time.Here is below my current code snippet that plots 1 and 2 sigma at the same time of 2 covariance matrixes (matrix1 and matrix 2) :

Code: Select all

```
# Call triplot
g.triangle_plot([matrix1, matrix2],
names,
filled = True,
legend_labels = ['1240', '1565'],
legend_loc = 'upper right',
contour_colors = ['red','darkblue'],
line_args = [{'lw':2, 'color':'red'},
{'lw':2, 'color':'darkblue'}],
)
```

**contour_levels**for example in the function**add_2d_contours**but I don't know how to use itin

**triangle_plot**for plotting only 1 or 2 sigma contours.If anyone could help, this would be fine.
