Currently, the waveform of data acquisition only shows the point where the tag transforms from 0 to 1 or from 1 to 0.
Which simply connects all the uploaded points(according to the picture below) to represent the trend. (this is our current logic, and is the most commonly used logic)
if you would like to keep the last value until a new value appears. For example, if the pump is on, the value of tag becomes 1 and stays 1 until it stops. When it stops, it shall go to 0 and stay zero until it starts.
This type of waveform can be chosen on the new version starting from Dec 31st.
