Hello,

I would like to draw a bifurcation diagram like this one.
The way I see it, I need

i) a curve that allows multiple "y" values for an x
ii) at a bifurcation point the curve should split

I 've had a look at the qwt classes, however I 'm not sure if any of the plots or sample series are suitable for this. Any thoughts as to which should be used would be appreciated.
