pnt2x

pnt2x (waveName, pointNum)

The pnt2x function returns the X value of the named wave at the point pointNum. The point number is truncated to an integer before use.

For higher dimensions, use IndexToScale.

Details

The result is derived from the wave's X scaling, not any X axis of a graph it may be displayed in.

If you would like to convert a fractional point number to an X value you can use:

leftx(waveName) + deltax(waveName) * pointNum
