Sorry if this isn't the correct section to post, but I hope ya'll can help.

I have this chart. I need to have the actuals stop in october and not go to zero (they do in the selected data), and the projections just to start where the actuals end. I hope this makes sense and there's an easy solution.

let me know if you need to see my data selection.

Thanks in advance, I really appreciate it.
