You couldn't have three different Mark types on just two Panes, sorry.
You could be able to build a decent view using any two (of the three).
In some cases you'd be able to mimic Dot Marks (usually connected with Lines)
with the Text Labels -- using special ASCII symbols which resembles some shapes.
I'd prefer to use the two different Mark types (Lines & Dots).
Please find the attached.
