Creating a Trend History screen
- Let us open the “TrendOnLine” screen and save it as “TrendHistory”. The trend object must
have the following dimension: W:538 H:228.
- As we are going to use a lot of variables let us do their initialization on the “Screen Open” logic.
Press the button On Open to configure the script as shown below:
Sometimes it is necessary to adjust the Date format. The InduSoft Web Studio default is
MM/DD/YYYY. If in your case it is different, run the function SetDateFormat(“/”,”MDY”).
This function defines the Date separator (in our example is regular slash “/”, but it can be period
“.”, dash “-”, etc… ) and the order (“DMY”, “MDY”, “YDM”,… ).

- Double-click on the trend object and fill in the "Object Trend Properties" window as follows. Be
sure that the "History" option is selected
- Press the Horizontal Scale button and configure it as follows:
