Change line chart background color

I don't know of a way out of the box, but here are a few ideas you can pursue.

All ideas revolve around layering visuals. The line chart will be in the foreground, and these options in the background.

1) you could just add an image with these gradients and add it behind the line chart. The drawback is that if the y-axis changes, the colors may not match up...
2) You might be able to use a heat map custom visual to control the size and color which may change as your y-axis does. You could layer elements to hide descriptions on the heatmap, then put the line chart on top... Basically it would be something like, create the heat map, turn off all title, etc. Use a white box picture to cover the remaing text, then add your line chart.
3) A final option would be to use a visual and drop in a single value so nothing shows up. remove all titles, axis, etc. and add a color for the background. You will need 3 of these, and they could serve the same purpose as #1

All these ideas are just that, ideas. i haven't tested or brought them to completion to see how they may work.
