Issue in XYSplineRenderer

Postby suchiandharia » Mon Oct 31, 2011 10:11 am

When I tried to use XYSplineRenderer, the chart and has two issues:
1) It does not have a smooth curve and has corners points
2) the graph line goes below and above the actual values

Note: I am unable to attach an image here in the post.

The first issue is resolved by passing "precision" in constructor parameter.
Does anyone have solution for second issue?

What issue? The "smoothness" of the curve should be corrected by the precision parametzer as suggested above, and the issue with the curve going above or below the actual data points cant be solved. If you interpolation a spline between data points, and the y values of the data points are not monotonously increasing or decreasing but go through some kind of minimum or maximum, then the interpolation curve may gop easily above or below the data points.
