Another question re QwtPlot::closestCurve

[Tony W. <Ton...@nr...>]

Hi

QwtPlot::closestCurve has worked very nicely for me when
clicking on a plot and finding the point in the nearest
curve.

However I now have a (potential) situation where points
from two separate curves could have identical values and
so lie on top of each other. I assume that QwtPlot::closestCurve
will (probably) return the value for the most recently
plotted curve (?), but how would I go about getting the
parameters for the second curve?

Thanks

Tony
