Greetings,

Is there a way to incorporate the use of TGraph and/or TGraphAsymmErrors.
The distribution I am attempting does not come in equal binning.

In fact much of the distributions that would be used will look similar to data like:
	double xval[] = { -0.84, -0.75, -0.65, -0.55, -0.45, -0.35, -0.25, -0.15, -0.05, 0.05, 0.15, 0.25, 0.35, 0.45, 0.55, 0.65, 0.75 };

  double yval[] = { 0.0324, 0.0374, 0.0276, 0.0233, 0.0173, 0.0122, 0.0122, 0.0169, 0.0277, 0.0333, 0.0359, 0.0375, 0.0439, 0.0625, 0.093, 0.132, 0.1634 };


Where x is cos(theta) and y is differential cross section.

If this is not possible, I will attempt to do fitting and use the 2D functional forms.
