Setpoint Trend Line without Linear Interpolation
Hello, I am still new to Compact HMI and am trying to overlay a setpoint and actual value on a trend. Since the setpoint is only updated infrequently, any change in setpoint causes the trend line to extrapolate linearly from the first point to the next. I'd prefer a piece-wise or step type behavior, where a change jumps immediately from the current setpoint value to the next as opposed to interpolating. I'm guessing this isn't happening because the OPC value is only updated when the actual value changes in the controller. Is there a way to configure the behavior I'm looking for? Thanks.
