i5SPC Chart range calculation wrong when all values are negative

[Former Member]

Hi

It is looking that i5SPC chart calculation (MII 1.5) do not calculate RANGE (XBAR-RANGE) properly when all values in the subgroup (point) are negative.

To illustrate that I am using chart with 4 points :

Point 1, has values :  0.002 ,    0.0019,    0.0018

Point 2, has values :  0.0004 ,  0.002,      0.002

Point 3, has values : -0.0019 , -0.0019,  -0.002

Point 4, has values : -0.0047 ,  0.0006,    0.0023

Points 1,2 and 4 have RANGE calculated correctly, but point 3, instead to show range point  0.0001 show 0.002

On SAP MII 15.0 SP4 Patch 11 (Aug 28, 2015) the bug(??) is confirmed.

I guess the customer can't update MII in the short run. Are any recommended suggestions / workarounds available (including modifying the JS libraries)?
