Ability to put a marker on Gauges
It would be great if we can add an extra UI (any UI shape , triangle or arrow shape) on Angular or Solid gauge chart to indicate extra value(probably a target value or goal value) other than the current value.
I know I can put a label anywhere (with x,y pixel values) but this is not dependant on the location of the value on graph. It would be awesome if I can put "marker" (one or more?) with a series data value to insert a shape or something similar.
One way to do it would be to add a static dial: http://jsfiddle.net/highcharts/mgucea1x/, but you are limited to the options given for the dial shape.
