matplotlib Legend Markers Only Once

Question

I often plot a point on a matplotlib plot with:

x = 10 

y = 100 

plot(x, y, "k*", label="Global Optimum") 

legend()

However, this causes the legend to put a star in the legend twice, such that it looks like:

* * Global Optimum

when I really want it to look like:

* Global Optimum

How do I do this?

Answer 1

You can change the matplotlib rc parameters dynamically in every python script. To achieve this goal.

from pylab import * 

rcParams['legend.numpoints'] = 1
