Static Y-Axis Scale on Radar Chart

[jkilber]

I have a radar chart built with a slicer attached. When I slice the data differently, it changes the scale of the radar chart, which makes the charts hard to compare. How do I keep the radar chart y-axis scale the same? 

The data values are from 1 - 5. I'm wanting the outer ring to stay at a value of 5 and likewise, the center, 1, no matter which sliced attribute I select. 

How do I set a Y-Axis values/scale to remain static no matter the selection I make in the slicer? 

Thanks for any help!

Let's say, if you have a table as below

Then you'll need a calculated table as

auxiliary Table = DISTINCT(yourTable[your orginal category])

Then create a measure as

Measure =
VAR val =
    SUMX (
        FILTER (
            yourTable,
            yourTable[your orginal category] = MAX ( 'auxiliary Table'[category] )
        ),
        yourTable[value]
    )
RETURN
    IF ( ISBLANK ( val ), 1, val )
