Min/Max on Radar

[MarioPerini]

I probably missed something.
To make sure the problem is not on my side, I'll open a discussion before reporting it as an error.

I need the radar starts at a higher value than 0.

• i tried to set the minimum value via a function function(min) { return min } and get only NaN as label
• i tried to set a minimum and a maximum value via a function function(min/max) { return min/max } and i get only 1-5 as scale, the values are far away from the diagram
• i tried to set min (also combined min/max) with an integer (50/100) and the chart shows the expected range of numbers, but the radar values of the chart are gone of the radar

Here is a pen and the code to try starts in line 40 of the JS
