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. 

73% of original size (was 692x19) - Click to enlarge

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

Hi Eyon,

To specify an axis range you must change the axis view to range axis view - for exampe:

NChart chart = nChartControl1.Charts[0];
chart.Axis(StandardAxis.PrimaryY).View = new NRangeAxisView(new NRange1DD(0, 100), true, true);
nChartControl1.Refresh();

will limit the Y axis to show values in the range 0 - 100. Is this the functionality you're looking for? - or maybe you want to allow the user to also use scrolling / panning - if this is the case just let us know and we'll post code to accomplish this.

Let us know if you have any questions or meet any problems.
