Getting data from an XY Graph curve

[patrick54]

I have a XY graph with the X data spaced every 0.2 (0.00, 0.20, 0.40,
etc.). After I display the graph I use the curser to manually (by eye)
find the inflection point in the curve (ex. 1.46). I would like the
software to determine the inflection point on its own, but LabView
only "sees" the array of points (spaced every 0.20) not in-between. Is
there any way for LabView to get data directly from the curve? ( I
have the Base package by the way - so no Curve fitting VIs)
