plot shaded areas between two vertical lines

Hello,

I would like to plot a time series with years on x axis and values between 0 and 1 on the y axis. I need to plot on the same graph another series that takes only values 0 an 1 and to shade the areas in which this is equal to 1. Hence I would need vertical lines when the series equals 1 and to shade the areas in which this happens.

Could anyone help me please?

Thank's

DId you try patch?

... or fill() but I lean toward using patch() as darova recommended.

since 2023a you can use function xregion.
