I'm trying to learn Perspective so please bear with me.
I have a Time series chart on my view and I have applied "Tag History" binding for 2 tags, Pressure and Flowrate.
But the DATASET is empty it show the time column for each record, but the Pressure and Flowrate column are all empty.
I have deleted the chart several time and started over but the dataset ends always being the same.
Time column, Pressure column, Flowrate column but pressure and flowrate are always empty.
My tags are working and they are updating every 30 seconds. The are opc tags.
