📖HomeBack By definition a Progressive Total is a value that increases without being reset, for example a flow total or the run hours of a motor.
This example shows a trend that has a progressive total trend, rendered in typical interpolated fashion, alongside which is a daily totals bar graph that has been derived from the progressive total. In this case the progressive total data is updates only once a day at midnight. This means that there will be at most one historic value per day.
This picture is a zoomed in version of the first picture:
To achieve the bar graph which displays the daily totals involves finding the min last for the day and subtracting it from the max last for the day. If there is zero or one historic value for the period this method will correctly calculate the bar graph. Using a Delta or Range doesn't work unless there at least two historic records in the period you choose (in this example the period is one day). Unfortunately, there is no way to offset the bar graph so it neatly aligns with the day (00:00 - 23:59).
The configuration for the bar graph is as follows:
