Summary0000229: chart lines lie and jump up and down
DescriptionOnce samples for a non-HD graph are dropped, the graph from the start time (Y axis) to the first valid sample is bogus and may even jump up and down. The line for these times is usually a 'lie' because it does not truthfully represent the values at the graphed times. Moreover, the line may jump up and down when further old samples with varying values are dropped.
  My suggestion is twofold:
1. Do not draw a graph for which there is no data known.
2. Use the same recording interval (time from first sample to last sample) for all parameters (temps in this case).
Steps To ReproduceDisplay the HD temp and at least one other value (e.g. CPU temp). Wait for 20 minutes or so, until samples for the other (non-HD) graph(s) are dropped at the beginning of the time window.

Of course I wanted to select category 'Logging and charting' -- maybe I lost it when I created the profile, sorry.

With a naive implementation (32bits per sample), in a bad case (16 temps, 16 fans, 16 voltages), with a sampling interval of 3 seconds, about .24MB per hour are needed to record all values, so keeping the recording intervals the same looks doable.
