I was looking at some examples and one thing caught my eye. In the example below
the graph appears smooth around the surface(appears to be a spline curve) but when I tried to implement the same the smoothness is gone(appears as a normal curve). Any apparent reason why this is happening.
FastLineRenderableSeries which is used in line example which you mentioned doesn’t use spline interpolation to draw line. It has many points in data series which results smooth line during rendering but under the hood it still draws straight line between each pair of points.
