---|---|
rvInfo[1] |
Index of the found data point, starting with 1 |
rvInfo[2] |
x-coordinate of the found data point |
rvInfo[3] |
y-coordinate of the found data point |
Parameters
- rsX
rsX x-coordinate of the data point.
- bInterpol
If bInterpol is TRUE (1), the function returns for the given x-coordinate a linear interpolated y-coordinate and the index of the data point which is closest to the given x-coordinate. If bInterpol is FALSE (0) (default value), the function returns an x-/y-coordinate and the index of the data point which is closest to the given x-coordinate.
Comment
The x data of the dataset must be of monotone increasing or decreasing order.
