Select series(lines) in a line graph by adding userform with checkboxes on a chart

I want to add a user-form on a chart, which will have check-boxes that will allow me to select series(lines) that I want see and compare in a chart. Currently my line chart has 24 series (Lines) which makes the chart very difficult to view and looks very busy. How do I add list of check-boxes that will allow me to select one or multiple lines that I want to see at a time?

Thank you in advance for your help.
