radar plot issue

[Paddy1985]

Hi all, 

Very silly question, I've got 6 variables which i want to plot as reference vs actual data. 5 variables behave as I'd like them to, although the 4th [symmetry axis] seems to want to jump back to the origin and will only show the maximum data (being this the reference or the actual data) and ignores the other. 

See picture 1 for when the reference data is larger

See picture 2 for when the actual data is larger

VI attached with actual values saved, any idea what I'm doing wrong? I'm out of ideas...

Without going too deep into things, I believe the issue is inside "Scale Axis.vi". The autoscale function uses the minimum value of all data points as the axis minimum for all axes. Since that 4th variable happens to contain your minimum value, one of the points will always evaluate to be exactly equal to the minimum and therefore the interpolation between min and max will always be zero which means there will always be a point at the minimum which is zero distance from the center. It looks better (or at least more understandable) if you turn off autoscale.
