removal of points from TGraph

Hello,

When I plot data using a TGraph I see that it is possible to remove points by right-clicking the mouse and selecting the appropriate option from the pop-up menu.

Does this delete those points from the underlying x,y arrays of the TGraph, or just from the display? I need to know if the "removed" points would be used in a subsequent fit of the data.

If removal does not edit the underlying arrays, then is there a method by which I _can edit those arrays (preferably some graphical method)?

Thanks for any help,
