Preparing some data

I am trying to put this data in Power BI . Its a date for a sales event split by each group. How can I use a slicer so that whenever I choose any group I can see the graph changing for the sales of that group only across the date frame.

The only way I see it is that I need to edit the original data so that I can have three transactions per date, but that seems to be tidious. Can anyone help
