Subject: [PATCH] Give the users customizable axis label limits (Fixes #2085)
 (#2894)

* Give the users customizable axis label limits (Fixes #2085)

This change adds the ability to users to override the imposed limitation of at least 2 labels per axis and at most 25 labels per axis at their own risk. By default these customizable limits are hardcoded to the previous limits, at least 2 labels, at most 25.

* Type inference was enough to declare 'axisMinLabels' and 'axisMaxLabels' properties
