Measure formatting - "Measure Expression"

[johnnyjohn]

Hello, I'm trying to understand what this option is when formatting a measure. "Measure Expression". I have a feeling it might be useful for what I'm building but struggling to find any documentation. Thanks

It means to apply functions like: num(sum(AnyValue, 'MyFormatPattern') if to the default-formatting a different formatting should be used. Possible are also custom representations for numeric values, for example things like:

dual(date(MyDate, 'DD.MM'), daynumberofyear(MyDate))
