Very nice! I just tried it on Linux, with Mono, using IronPython with
the following:

import clr
clr.AddReference("Florence")
clr.AddReference("Florence.Gtk")
import Florence
import System
plot = Florence.GtkSharp.ImperativeHost()
plot.Start()
x = System.Array[System.Double]([1.0, 2.0, 3.0 ])
y = System.Array[System.Double]([ 1.0, 2.0, 3.0 ])
z = System.Array[System.Double]([0.0, 2.0, 4.0 ])
plot.points(x, y)
plot.lines(x, z, title="Test Plot 2", x_label="X2", y_label="Y2")

Clicking on the graph (in the middle, and on legends) is fantastic,
and using it interactively from IronPython really turns this into a
powerful tool. (If you run this from Calico [1] (which will include
Florence shortly), the first three commands aren't necessary if you
put the DLLs in Calico/modules).

I'd be glad to fork on github, and suggest at least a couple of
additional comments. Thanks again!

[1] - http://calicoproject.org/ - use Florence from a variety of
interactive languages, including Ruby, Python, Scheme, and more.
