How to decide the balance of the pie percentage?

[chantal]

I noticed these two errors:

ERROR: pandas 0.24.2 has requirement numpy>=1.12.0, but you’ll have numpy 1.8.0rc1 which is incompatible.
ERROR: pandas 0.24.2 has requirement python-dateutil>=2.5.0, but you’ll have python-dateutil 1.5 which is incompatible.

Will try again…
