python: add another point in the triangle/corner plot

Question

I am using the triangle/corner plot from python and I follow the simple guide in this webpage . Everything is ok but I was thinking about adding another point in the triangle plot. As you can see from the example, the command to draw the triangle plot with a particular point is:

fig = triangle.corner(samples, labels=["$m$", "$b$"],truths=[m_true, b_true])

in which m_true and b_true are the coordinates of the blue square. How can I add another point with different coordinates, let's say {b_true2, m_true2} ?

Answer 1

You have to edit over the ax . So if you want to plot something above, you have to do:

1. figure, ax = pl.subplots(1, 1)
2. figure = triangle.corner(samples, labels=["$m$", "$b$"],truths=[m_true, b_true])
3. ax.plot(...)
