Help wtih field parameters

[Anonymous]

I have a visual (screeshot below) which is populated with four values from a SQL server database, apparently in Direct Query mode.

I want to have a slicer which allows user to show/hide which line is displayed on the chart. I know that this is a field parameter issue but I'm not sure how to implement it.

Thanks in advance
