Tips and Tricks for the Variable Trend

Predefined trend display groups "MIN-MAX", "ALL"

Two predefined curves enable you to work with the Variable Trend.

When called correctly, the "MIN-MAX" trend display group shows a trend display depicting a black measured value, the red minimum and the green maximum curve.

The function call for a compressed data point "TEST" would be:

openTrendCurves("MIN-MAX",-1,makeDynString("$CURVE1:TEST.C1.AVG","$CURVE2:TEST.C2.MAX","$CURVE3:TEST.C2.MIN"));

The Variable Trend automatically opens and displays in a new module.

The trend display group "ALL" contains 8 predefined curves that you can use to display 8 data points. Permissible compression levels are C1...or C? or C? + 1. C? provides all data point compression levels (see "AUTO" compression level).
