Track step change in scatter plot

Recommended Posts

Hi Tranquil - While not specific to XY plot, Seeq does have formulas that help you detect step changes in signals.  If you are looking for changes in the samples coming in, I would suggest you explore the


formula, which compares sample-by-sample changes.  For instance, if you want to generate a "Step Change Condition" whenever the change in signal is greater than 3, you could write it as:


Once the condition is generated, you can filter your XY plot by that condition. 

To count the number of changes for a time period, you can apply a Signal from Condition or Scorecard Metric to count up the number of step changes. 

Example of a Simple Metric:
