Hi,
I checked again settings of the chart :
Elapsed time type is set to Time
Power type is set to continous
W'Bal is set to continous
the gap between elapsed time is 12s
I made another setting :
Elapsed time type set to Time
Power type set to Time
W'Bal set to Time
Elapsed time is the same for both charts.
But obviously, y-scales have changed and are not correct.
That seems to be curious.
When I uncheck 'single series per plot' in the chart settings and we have both curves drawn on the same chart, all seems to be correct.
Bernard.
