Powerchart: interpolation "curveStepAfter"

Alternatively, I think you can also change the Deadband Style to Discrete under the tag’s History config

This is the key.

Power Chart Interpolation

I'm pretty sure the display.Interpolation property is applied to the displayed trend data after the points are aggregated and interpolated from the historian raw data to match the required point count. These trends are both incrementing second counters. The green has an analog deadband style and the orange is discrete. Other than that they are setup the same with a deadband of 5. The display.Interpolation is set to curveStepAfter. Setting the pointCount to a high number make the charts interpo…
