I'm looking for a manner of drawing arrows pointing down at various positions along the top axis (outside of the data space), and not sure how to accomplish it. I've attached a picture of an example of what I'm trying to accomplish - it may involve more than one symbol type. The symbols are associated with x-axis values.
Can this be done by using custom labels somehow?
Can it be done by using the arrow series? I can't see how to plot the series outside of the standard chart space. Would this involve perhaps adding an extra axis into the chart to divide the chart or perhaps adding an extra chart?
Maybe even using the Marks feature somehow?

I guess I'm looking to get pointed in the right direction. Any assistance would be greatly appreciated.

I've ended up going with a second chart that uses the arrow series, with linked bottom axes and disappearing most of the background stuff. That seems to be good enough.

Hello,

I'm glad to hear you found a satisfying solution. Anyway, I think it would be easier to load an image of an arrow (or any symbol you would like) into a Rectangle tool. Alternatively, if the symbols to draw are as simple as an arrow, I'd also considered drawing them manually at AfterDraw event.
