@bowesmana  Thanks for the suggestion. But still, I could not able to see the smooth line profile. It is somewhat looks like sawtooth.     ... View more

What's the visualisation - scatter or line chart? What does your data table look like? Ans:-  Its a scatter plot. here I would like to increase the marker size for orange dots and reduce marker size for green & blue dots.   My data table looks like as below:-   X dist Y green 130 -0.0051 blue 130 0.0051 orange 130 0.0015 green 129.99 -0.005 blue 129.99 0.005 green 129.98 -0.005 blue 129.98 0.005   ...

@bowesmana Thanks for your suggestion.  with that query, I was able to create the below graph. But if you see the boundary lines (green & blue), though it looks like a straight line but not smooth because for every value of xaxis, green & blue line values are computed with the line equation. So my aim is to make the line as smooth as possible.    1st question:- I would like to consider few random points between xaxis value 15 and 130. and interpolate between the random points.   Any leads are welcome on how create a interpolation.   2nd question:-  Is it possible to increase the marker size for orange dots and reduce the marker size for blue and green lines.   Any leads are welcome.     ...
