Hello, 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? Example: How do I get the y-axis value which is reached by the green curve in http://matplotlib.sourceforge.net/_images/histogram_demo_extended_021.png a x-axis value of in 175? I could proably use a solver from numpy like http://docs.scipy.org/doc/numpy/reference/generated/numpy.linalg.solve.html#numpy.linalg.solve but if I plot a distribution, the equation of the envelove is unknown at the first place. I'd appreciate your help or pointers to examples.
