How can I create a trend (cumulative) chart always using the latest data from a PI tag in PI Vision?

I have a PI Tag that collects information from a rain gauge, but I need to create a chart that shows the accumulation of the last 20 readings, in order to see if this accumulation exceeds a limit that would trigger an alarm.

You can create an event triggered analysis triggered on your rain gauge.
Two variables:
Values: RecordedValuesByCount(<Rain Gauge>,'*',20)
Sum : Total(Values)

This will give the total of the last 20 readings; map it to an attribute with a tag.
