Description
in QGIS > 2.14
I also think that the tool is missing a parameter to allow group the points, otherwise it will be always computed the CH of all the point of the input dataset.

Sorry Alex, I have to reopen. On the latest master on osgeo4w:
2016-10-03T01:48:27 1 There were errors executing the algorithm.
