Where you have a single numeric field (e.g. 'Value') in your table though each row represents a different measure name (and/or unit for example) then you can create a dynamic measure to be displayed in your report.
You will need to create a seperate table with a single column (e.g. through 'Enter Data' in the Query Editor) containing just the unique list of measure names, and use this field as a slicer.
In the example attached, there are multiple types of reading values, and each of these reading values can be expressed in one or more units of measure. A list of unique measure names is included as a table called pMeasuresList and each of the units of measure is in a table called pUnitNames. The fields from these two single column tables are included as slicers on each page.
The dynamic measure to then return the value of the selected measure name/unit of measure is:
Average Measure Value =
VAR MEASURENAME = IF(HASONEVALUE(pMeasuresList[Measure Names]),VALUES(pMeasuresList[Measure Names]),"Tidal Level")
VAR UNITNAME = IF(HASONEVALUE(pUnitNames[unitName]),VALUES(pUnitNames[unitName]),"mAOD")
RETURN
CALCULATE(AVERAGE(Readings[value]),'Measures 1'[qualifier]=MEASURENAME,'Measures 1'[unitName]=UNITNAME)
Note that this has a default value - so if the user has not made any slicer selections then it defaults to the reading "Tidal level" shown in Unit Of Measure 'mAOD'
The same principle can be applied to the title, so that the report page title reflects what is being shown in the graphs:
Title Station Analysis =
VAR MEASURENAME = IF(HASONEVALUE(pMeasuresList[Measure Names]),VALUES(pMeasuresList[Measure Names]),"Tidal Level")
VAR UNITNAME = IF(HASONEVALUE(pUnitNames[unitName]),VALUES(pUnitNames[unitName]),"mAOD")
RETURN
MEASURENAME & " (" & UNITNAME & ") Station Analysis"
