Matplotlib - plot_surface : get the x,y,z values written in the bottom right corner

Question

I am a quite new user of matplotlib. When plotting a surface (3D) with matplotlib and plot_surface, a window appears with the graph. In that windows, on the bottom right cor

Answer 1

I tried @Thilo's answer and received only a single float. Using Python 3.8 and Matplotlib version 3.2.1.

Modified his function to this

def getxyz(event):
    s = ax.format_coord(event.xdata, event.ydata)
    out = [float(x.split('=')[1].strip()) for x in s.split(',')]
    print(out)
    return out

Many thanks, because without that answer I would never knew something like format_coord exist.

Answer 2

With ax.format_coord(mouseevent.xdata,mouseevent.ydata) you get the x, y, z values in a string ('x=0.222, y=0.452, z=0.826') from which you can extract the values.

For example for y-coordinate:

def gety(x,y):
    s = ax.format_coord(x,y)
    out = ""
    for i in range(s.find('y')+2,s.find('z')-2):
        out = out+s[i]
    return float(out)
