Charts rendered without axes or gridlines


We’ve got a problem with charts being rendered in an iPhone 7 (iOS 10.2.1) without the axes or gridlines showing. Dragging the chart slightly causes the missing elements to be added. We haven’t noticed this on an iPhone 6 running iOS 10.2.1 or a 6 Plus running iOS 9.3.3

Do you know what might be causing this? I was using ShinobiCharts 2.8.10 and have just updated to 2.9.3 and it’s the same behaviour.

EDIT: I’ve just found that disabling loadDataInBackground seems to stop this behaviour but I’m not sure if this is a suitable fix for some of my charts
