Hello,
I was hoping for some help with Easy Chart component to visualize tag history. I am using version 7.9.16. I use a chart like below, two colored lines are temperatures from RTD, the black line is a set point. These are all configured to store tag history. This doesn’t happen consistently, but frequently the set point line is not displaying correctly. In the graph below, the set point changes from 70 to 60 to 30, but the graph displays it as a diagonal instead of steps. Is there something I can change about tag history parameters or chart properties that will help with this? Is it possible its because a SP doesn’t change for days at a time, and I have tag history set to “unlimited time between records” that the chart is interpreting long periods without change as interpolation and is connecting the dots that way?
