I record average (also max/min) data (Heart rate, Climb rate, descent rate)
against either duration or distance. The graph in its simplest form should
look like a series of horizontal bars showing the average, the length of the
bar being duration or distance covered.
Stock charts show the this min,avge,max value but the width of the vertical
bar his constant and does not vary with the duration or distance.

How do I create this?
Thanks, Pierre
