Hello everybody,
I would like smoothing curve using S-G method; I tried this:
//Open a new worksheet
win -t data Origin;
//Import sample file
open -w %YSamples\Data\Data with noise.dat;
//Create a column for results
wks.addcol(Result);
//Assign datasets
curve.data$ = DataWithNoise_Signal;
curve.result$ = DataWithNoise_Result;
curve.polyDeg=3;
curve.smoothLeftPts=3;
curve.smoothRightPts=3;
curve.SGSmooth();
But it doesn't work;
could someone help me please?
Thank you very much,
B.R. |

Ok thank you, and for Polynomial Order? I want 3, is curve.polyDeg=3 good ?
Yes... according the programming guide its values can range from 1 to 9.

The curve object does not do the math on its own so you must set all three properties.

You must also use curve.smoothPts=7 or that property will default to 5 and curve.smoothLeft(Right)Pts will revert to 2.

Thank you, but why curve.smoothPts=7 (why 7 ?) and why curve.smoothLeft(Right)Pts=2 ? I would like curve.smoothLeft(Right)Pts=3 or 5, is it possible ? |
