Information data on profile chart

[Tim Wootton]

I notice on all of my profile charts that the information shown in the
information panel does not correctly reflect the value on the trace at
the point that was selected. e.g. on my last dive, if I use the profile
chart to view the depth 25 mins into the dive, the info panel shows
12.3m, whereas the chart line and the log seem to agree that the correct
value at that time is 11.1m, it has 12.3m as the correct depth at 23.5
mins into the dive.

The time discrepancy seems less pronounced on the left of the chart
compared to the right. Is the info panel basing it's value on the
assumption that the dive data fills the whole chart, my dive finishes
about 3 mins before the right hand side of the chart (padded out to the
next 5 min grid-line)
