WebJan 21, 2012 · This gives the difference between the highest and lowest X-value that have Y-values larger than half of the maximum Y-value. That means that you will get a slightly lower value than the "width" that you ask for. If this is not acceptable, the formula can be extended to do a linear interpolation on the X-Y values near the points where Y is Max(Y)/2.
