I have about 15 series in my chart and do not wish to manually select and edit each one individually to give it a distinct marker
Is there a way to do this for all lines in one go?
I don't care if the shape/type of marker is randomly assigned as long as they look different

To close the loop on this question, I'll move a comment to an answer. The problem appeared to describe selecting a chart style with no markers. The solution to that is using the "Select Chart Type" button to pick a sub-style that shows markers on the icon. Chart types can be changed after the chart is created. The comments indicate that this was the issue.
