• Smartphone OS (iOS or Android) + version : Google Pixel3 XL (Android9)

The same Vitrual pin (V3) is used to display values in Labeled Value and SuperChart.
What I regard as a problem is the attached photo “EXT_TEMP”.
You can see that the Labeled Value text shows about 7degreeC below 10degC.
However, SuperChart displays “-” indicating invalid data although it should refer to the same Virtual Pin, and the graph line is stable at 10degC.
I was unable to find a feature in SuperChart that limits the upper and lower limits of the value. What causes this phenomenon?
