force grid to be on top of patch

I'm referring to this question:

https://www.mathworks.com/matlabcentral/answers/74575-how-to-add-two-vertical-lines-to-plot-and-color-between-them

How can I add grid to the figure which is not covered by the patch color?

If you mean the kind of grid you get from "grid on", then set the axes "Layer" property to 'top'

Thanks. But it brings the grid on top of the curves as well (white lines on the curves). I want the grid to be behind the curves but still not covered by the patch color.

Use two axes in the same position. The one with the patch is drawn first and has normal background color and grid turned on. Anything that should appear above the grid goes onto the second axes, which should have background color 'none'

In theory yyaxis can be used for this purpose, if you turn axes visible off for the right axes and grid on for the left axes (with the patch)
