I have a chart with a time-based X axis using IGCategoryDateTimeXAxis. The chart logs data in realtime over the course of about an hour.
I'd like the x-axis labels to only display HH:mm instead of the full datetime, but I can't find a property on the axis that lets me set the date formatter.
I'm using Swift 4.
I found the IGCategoryDateSeriesDataSourceHelper.labelPath property, so I added a label property to my data model object. But setting that doesn't seem to be changing t.
