The only way you'll be able to do this (some lines are solid, some lines are dashed) is to create a custom graph where you have stacked line charts on top of each other. I think you might be able to get away with two line charts where one is for Actual and solid, and the other is for Previous and dashed but depending on your data you might need more.
If you've never used Graph Builder, the documentation is here (https://go.documentation.sas.com/doc/en/vacdc/v_031/grbldrug/titlepage.htm) and the basic flow would be something like this: - Create a new graph in Graph Builder
- Drag and Drop two line charts on top of each other
- In the Options for Line Chart 1, make sure line style is solid (default) - In the Options for Line Chart 2, change the Line Style to dashed. - Turn on other options for each as you see fit, like Markers, data labels. - In the Roles for each line chart, edit the Response/Measure role and check the box for allow multiple measures. This should allow you to add all of the Actual measures to one line chart, and all of the Previous measures for the other line chart.
This may take some trial and error to get it right but hopefully that's enough to get you going!
