CPlotView:GetPtErrY
The GetPtErrY method returns the y errorbar value of a point in the class data matrix.
yErr = CPlotView:GetPtErrY( n ) |
This method returns the y errorbar value of the specified point at index n. If n is out of range, the value 0 is returned. To remove ambiguity about whether the point truly has a y-errorbar value of 0 or is out of bounds, check the index before calling this method.
The following script fragment adds some points, then finds the nearest point and prints its y errorbar value:
|
-- create a new CPlotView |
|
-- add a point |
|
-- add a point |
|
-- get index of point nearest 4,72 |
|
-- result: n = 1, yerr = 12.4 |
