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?

    This should work:

    legend(numpoints=1)
    

    BTW, if you add the line

    legend.numpoints     : 1      # the number of points in the legend line
    

    to your matplotlibrc file, then this will be the new default.

    [See also scatterpoints, depending on your plot.]
