Historical Trend

Historical Trend

Dear All, I am having Pressure, Temperature and Flow values from PLC. The comparison purpose I would like to add the variables at runtime. I can achieve this by "Diagram..." function which is available in Trend Template in default. But customer is no need that much settings which is available in Create Diagram window (Ref: Trend-Setting.jpg).They like do add and delete the curve when they need comparison at run time. So Please explain How can we do the following task in zenon, There are three Combo boxes will be available in Trend screen. One for selecting pressure, second one for temperature another one for selecting Flow. If I want to compare the pressures, I can select the variables from Pressure combo box which is need and If I want to compare the temperature, I can select the temperature and I will delete the existing variables. Best Regards, A.Navaneet.
