Dragging mouse question [message #3964]

Hello everyone,

I have written a (very simple) procedure which displays data points on an xy-axis
and allows you to manipulate them using the left mouse button (i.e. it just uses
tvrdc,x,y,/down to get the point-within a specified range-and reads the position of
the next click to place it).At the moment all it does is re-plot every time you move
a point and although it is satisfactory for my purposes it takes a while to get the plot line looking smooth.Clearly it would be neater if i could drag the points and have the screen continually update the plot so i could see the original line itself moving
with the cursor.I expect it to be fairly simple but have looked in the IDl manual/reference guide and at the library routines for clues and have found nothing helpful.Does anyone know what commands i should be using? Any help would be
appreciated.

Cheers,

David
