Furthermore the displayed timezone in the graph is GMT. Which means is if your timezones that are specified are not GMT (e.g. your local time) then the graph vertical lines for the days will be when the day changes if it were GMT.Intelligent AveragingWhen you zoom out technically no averaging occurs. A sample point is chosen intelligently and peaks are given high priority. This allows you to see disturbances in your data such as outliers. One disadvantage is that the graph may look jittery as you move around at a very zoomed out level.
