Hi Dan, I've been meaning to write you a reply but been snowed under
with work :(

You're missing calls to gtk_plot_paint(), I think. The GtkPlot widget
is a little non-standard and needs a few extra functions to handle
resize and repaint.

You're welcome to steal code from (this part of) my app if you like.
This makes a gtkplot preview which you can embed in another widget:

And this is a floating window showing a plot:
