Why is the xAxis Value Formater so often called?

[dadidu67]

A chart with only 20 values and 6 xAxis labels calls the formatter many time with the same value. Waste of resources:

func stringForValue(_ value: Double, axis: AxisBase?) -> String

value: 3.0
value: 6.0
value: 9.0
value: 12.0
value: 15.0
value: 18.0
value: 3.0
value: 6.0
value: 9.0
value: 12.0
value: 15.0
value: 18.0

Please provide a reproducible code sample.

close as no update since then. reopen with details. only pasting a lot of logs does not help at all.
you should check your calling stack who's calling it.
