I have a similar problem to:
Suppose I plot a line from (0,0) to (1,1.5) to (2,2). Now I want to mark
(1,1.5) with a green circle. How is that done?
I am performing a curve fit and also showing a distribution in my plot.
In order to help the reader to evaluate the result I would like to draw certain
boundaries (vertical and horizontal line).
While I am aware on how to draw such lines, I would like to know wheather there
are some functions in matplotlib which help me to retrieve the coordinates
a) at which two curves intersect
b) at which a distribution reaches a certain value?
How do I get the y-axis value which is reached by the green curve in
a x-axis value of in 175?
I could proably use a solver from numpy like
but if I plot a distribution, the equation of the envelove is unknown at the
I'd appreciate your help or pointers to examples.
Thanks a lot in advance,
