Look in the following section
Play with the 0.020 and 0.60 factors.

; Part 2:
; Correlation labels
; ----------------------------------------------------------------
radC = xyMax ; for correlation labels
xC = radC*cos(angC*rad)
yC = radC*sin(angC*rad)
; added to get some separation
xC = xC + 0.020*cos(rad*angC)
yC = yC + 0.060*sin(rad*angC)
