Beyond visualizing regular signals, Marple Insight allows you to apply functions to signals—or combinations of signals—to create custom variations.
To view applied functions, switch to Functions in the Signal List.
This panel shows all functions currently added to your project.
To get to an overview of all functions in the entire workspace, or to create a new function, click on the Browse button.
This will open the Function Library.
The function library shows a list of all functions that have been created in your workspace.
If you would like to create a new function, click the Create button in the bottom left of the dialog.
The syntax for writing custom calculations in Marple Insight depends on the database it is connected to. For example, if the connected database is Azure Data Explorer (ADX), the correct syntax to use is the Kusto Query Language.
For convenience, you can search for signals on the right side and click on their names to insert them directly into your formula. When writing your custom formula, make sure to enclose signal names in double brackets (e.g., [[SignalName]]).
You will see a preview of the function signal displayed in red in the preview window.
Next, you have the option to resample the time base of the input signal. This feature allows you to combine signals with different time bases into the same function.
Finally, you can assign an appropriate name to the new signal for easy identification and use.
