Welcome to the community !!!
You have right information.
There are still now way to draw dash-line.
Closest way I know is using "dot" directly, but I don't think it's good for your case.
Changing the size should be much better...

Thanks Shin! Yeah that doesn't clarify much, so I may just have to go with 2 charts, one for each direction.... and hope the feature is added in the future!
I really appreciate the response. Thanks.
You are welcome and this is definitely the right place to ask any questions.
