Re: How to resample continuosly time data to be represented real time ?

For more precision, the "AveragesTaken" could be replaced by the timespan 
that each group/line/point on the chart represents.

And then transfer from group to group, and finally measurement to group...

For example:

// To process new measurement do:

OldGroupTimeSpan = GroupTimeSpan;

// calculate new group time span
ChartStopTime = CurrentTime;
TotalTime = ChartStopTime - ChartStartTime;
GroupTimeSpan = TotalTime / 500;

// Now compensate groups for new grouptimespan.

NewGroup1Value = (Group1Value * (OldTimeSpan/NewTimeSpan)) + (Group2Value
* 
((NewTimeSpan-OldTimeSpan)/NewTimeSpan));
NewGroup2Value = (Group2Value * (OldTimeSpan/NewTimeSpan)) + (Group3Value
* 
((NewTimeSpan-OldTimeSpan)/NewTimeSpan));
NewGroup3Value = (Group3Value * (OldTimeSpan/NewTimeSpan)) + (Group4Value
* 
((NewTimeSpan-OldTimeSpan)/NewTimeSpan));
NewGroup4Value = (Group4Value * (OldTimeSpan/NewTimeSpan)) + (Group5Value
* 
((NewTimeSpan-OldTimeSpan)/NewTimeSpan));
NewGroup5Value = (Group5Value * (OldTimeSpan/NewTimeSpan)) + 
(NewMeasurementValue * ((NewTimeSpan-OldTimeSpan)/NewTimeSpan));

Group1Value = NewGroup1Value;
Group2Value = NewGroup2Value;
Group3Value = NewGroup3Value;
Group4Value = NewGroup4Value;
Group5Value = NewGroup5Value;

These are just idea's... I didn't try any of them... but maybe they work
;)
