Scott, in this example you can select the overlay marker, connect color, line style, and other graph options for each variable (Y) after you create the overlay plot. You can do this directly from the legend. Left click on the variable in the legend (in the bottom picture, you would select DJI Close) and it becomes highlighted. Then right click to bring up options for the highlighted variable (in the bottom picture, when DJI Close is selected, you would select needle).
