<![CDATA[Suggestion - Don]]>Hi

When Mango is set to 'log point changes only' it becomes problematic when a value goes to zero, stays there, and then changes again:

In this example, the value changed to 0 at time A, then remained at 0 until a new value was recorded at time B.
This gives quite an ugly and perhaps misleading chart rendering. The only other option is to set Mango to 'log all data', but this - i assume - consumes DB space.

It would be nice if there were some workaround in Mango for this. Something like 'discard intermediate values and record first and last values for repeating values'.

Or maybe there's a workaround that someone can suggest?

Thanks.

for example,between tim A and time B,assume have 60 seconds ,if the query interval is 2 second,we will get 30 pointvalues,we will copy the time A 'value 0 to 30times, until to time B, then we can restore really situation.

I gave up on trying to fix this. I just set it to "interval" 1 min. For some reason I don't get zeros any more.
