detach only one qwt plot curve?

Hi,

How can I remove one of my plot curves from my plot without destroying the curve?

I have a plot curve that is plotted on the left y-axis, I want to be able to move to the right y-axis and not have the first curve on the plot anymore. I don't want to delete the first curve because I want to keep its data and just have it replotted on the right y-axis.

I can't use QwtPlot::detachItems because I have other curves that I want to stay on the plot.

Any Ideas?

Thanks!
