hello,

I have a function, which I am plotting. I want to add a line positioned at, say, the mean of the function, so I want to do plot([x,x],[y0,y1]).

In order to get y0, and y1, my brute force trial and error browsing of the API lead me to :

y0=gca().yaxis.get_majorticklabels()[0].get_position()[1]

y1=gca().yaxis.get_majorticklabels()[-1].get_position()[1]

.... and as I am never contented, I now ask : is it really the manner of choice to get this information. I sense that I did not take the straightest path to get it

thanks in advance,

Johann

line = gca().get_lines()[0]

y0 = line.get_ydata().min()

y1 = line.get_ydata().max()

should work (sorry I did not checked)
