According to Request #982621 it was not possible to plot Beta Charts for my Western States Endurance Run because the file size is too large. (28h activity)

Still it would be very valuable to have the beta chart feature for ultra running activities and races (especially as coach) but they tend to be rather long. (>10-40h) Why not make a selection of the parameters before attempting to plot every parameter? In order to avoid the large file size with all parameters.
