Thread: [Matplotlib-users] How to add data points to a contour map.

I am a beginner and I use Python 2.7 on an iMac OSX 10.9.5. Python is 
the Enthought installation.
I am doing simulation experiments. I have constructed a 2D contour map 
with my results and I am happy with the result.
I am wondering if it is possible to add the data points, say as red 
dots, on this contour map.
I have not been able to find an equivalent example in gallery and I am 
too much a novice to know what to do.
Any help would be much appreciated.

Definitely. Assuming you don't want to do this in an interactive manner
(i.e. pointing and clicking with your mouse:

fig, ax  = plt.subplots()
ax.contour(...)
ax.plot(x_dots, y_dots, 'ro', label='Dots')
-p

Thanks Paul. Works perfectly.
I should have been able to work that out for myself, but my format was 
wrong.
Cheers.
