hi,
i'm relatively new to programming using qwt. I'm working on a graphical tool that calculates the goodness of fit , as in curve fitting problems.
I am using qwtplotcurve for plotting the points and it is working fine. but i need to implement a functionality that enables the user to select and delete the displayed point(s). Whichever he/she wishes to delete. once that is done , i need to replot and proceed with the algorithm.. Could someone please advice me or post a sample code for the same. thanking you in anticipation !

I need to delete certain points from the screen .. and then replot the remaining points !!
