Is there a way to show the Marker (circle, square, etc) with a short line (of the correct color) in the legend? Right now it just shows the color of the line, but if you have a lot of series with markers it would be helpful to show in the legend.
it's not a feature of the chart at this time... the closest thing you could do is overlay UIElements on top of the chart to create a custom legend.
