I'm working with some PlotCharts, in which I display
gridlines, with solid color fills. My goal would be to change this
vertical fills when the user mouse overs them, to give some
feedback to the user. Can you do this some how with the
verticalfill property of the gridlines?
my only idea was to fight with some annotation elements,
drawing them over the graph were the user is pointing... but I hope
there's an easier soultion.
