I'm new to programming.  Well, object based programming and the concepts I have to get used to.

What I am trying to do is basically update the graph view/axes dynamically and interactively by using NTrackBar.  I'm using 4 trackbars, two per axis, that will allow the user to dynamically change the graph view.  These values are displayed in a textbox for the user. 



How does one dynamically update the range view using the endpoint values displayed in textboxes?  Any help for this newbie would be greatly appreciated.

Thanks
