Improvements need to be made and new API introduced in order to solve some indicator rendering issues and allow more scenarios to be achieved. At the moment indicators may get clipped when near the edges of the axis.
Different layout modes may be implemented so that the gauge ensures its elements will not get clipped. Also API for desired axis-indentation and manually setting axis-indentation will allow for a number of scenarios, for example aligning gauges in a column, and allowing to precisely determine the absolute position of a value on the axis, which allows easy interactivity.
Feature request to provide touch support for the Gauge control and the ability to find the element the user has tapped over such as: ranges, indicators, etc
Currently, the values of the labels are the numeric values according to the Step set. You can set a LabelFormat but no further customization to the value can be applied. We can consider exposing a LabelFormatter(as in the Chart axis) where you can control the value of each different label.
