Add shaded bars to seasonal chart to show summer and winter months

Hello folks,

I'm making a line graph that shows water consumption fluctuations over several years. Is there a way to make the background of the chart shaded for certain months of the year? For example a light blue shade for winter months and light yellow for summer? This shading would of course be behind the trend line.

I've added a sample excel sheet.

Please note this is my second post on this forum. I'm still learning my way around.

Kind regards,
Cameron
