efficient way to rescale plotReturn to overview

hi, i have 2 big plot. when the user select one of the (*2, *3, *5, /2, /3, /5) from each plot's combo box, that plot's Y rescaled ( for example *2). this is not a efficient solution to change all data.
is there any efficient way to do it?
thanks

Wait are you going through all your data points y and multiplying it by value?
You should probably try this:

plot->yAxis->scaleRange(2);
