Custom functions

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 brackets and quotes (e.g., ['SignalName']).

The preview window of the new function

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.
