XYGraph Xaxis grid settings

[Amien Crombie]

Hi 

I am struggling just to show on my Xaxis the '0' (zero) marker with a different color and line width.

As you can see from my code, I have xaxis range from -24 to 24

I need to show the zero marker with a different color and importantly a linewidth of say 2

var g = widget.getFigure().getXYGraph();

g.setTitle("PV name");

g.primaryXAxis.setRange(-24,24);

g.primaryYAxis.setShowMajorGrid(true);

Any help would be appreciated
