Perspective Powerchart Aggregation Mode

Is there a way to get the perspective powerchart to draw ‘on change’ datapoints correctly? I frequently have tag values that are constant for a long period, then suddenly change value. I can get the correct behavior in vision if I pick a raw or natural aggregation mode and Digital line type.
Example of the powerchart incorrectly simply connecting the dots:


Proper behavior, it assumes the value doesn’t change until it sees a new value.

Hi,
It has been a while but I was just wondering if you were able to fix this issue as I am having the same problem

Hi Jasmin, try setting the tag history's Deadband Style to "Discrete" and then, in the Chart Settings, Edit Pens Display Interpolation to "CurveStepAfter". Good luck

Hi,
Yes I implemented that yesterday and it is working like I want now. Thank you for your help though!
