On the ride plot, the range of speed is typically much smaller than the ranges of power, heart rate, and cadence. As a result, for many activities it's difficult to distinguish much difference.

This update changes the plot to use a right y axis for speed. This makes it easier to see speed differences.

Some other packages use separate y axes for each data type, but as far as I can tell, this is not available with the qwt library used by GC.
