symbols on top of each other in graph - how to separate?

[Jennifer Carson]

I'm producing the below chart. (Note: data is made-up).

For group C, there are 2 cases where the data values are the same number, and thus, the symbols are on top of each other, making it confusing. Is there a way to separate the symbols from each other?

thank you.

I would consider changing to symbols are visible even when at the same position. o and + are a good combination and open or holllow symbols better for this purpose than solid or filled.

Thanks! This worked well for this graph as there were a max of 2 on top of each other. I have another graph with 4 data points at one place. Is there a preferred combination for that?

Offsetting is the next trick.

Thank you! I will try that.
