CNV tracks are inverted

[menzel]

The axis of CNV tracks seems to inverted, higher numbers appear closer to the center, lower CNV's outside.
It is visible in the example for CNV's here:
https://cran.r-project.org/web/packages/BioCircos/vignettes/BioCircos.html

E.g. chromosome 2 has three CNVs 2,3,4 and 2 is higher up/ farther outside than 3 and 4.
(At least compared to BioCircos.js, one could argue that both directions are valid)
