Hello,
I would like to draw in grey color a certain part of the background in a plot. I know how to change the background color of the whole plot.I used this code after the plot function:
HANDLE = gca
get( HANDLE );
set( HANDLE, 'Color', [0.7,0.7,0.7] )
Exemple: y=x^2
How can I do to draw the blue part in grey and to leave the other parts in white?

if you're using a grid, how would you make the grid appear overtop the rectangle?

Below is an example comparing without and with that line. It also solves the issue that the rectangle appears above the axes black line.
figure
subplot(2,1,1)
rectangle(Position=[0,-0.5,0.8,1], FaceColor=[0.9 0.9 0.9], EdgeColor=[0.9 0.9 0.9])
hold on; grid on; grid minor
plot(-1:0.01:1, (-1:0.01:1).^2)
subplot(2,1,2)
rectangle(Position=[0,-0.5,0.8,1], FaceColor=[0.9 0.9 0.9], EdgeColor=[0.9 0.9 0.9])
hold on; grid on; grid minor
set(gca, "Layer", "top")
plot(-1:0.01:1, (-1:0.01:1).^2)

In case you are using a legend on your plot, what is plotted with fill will be listed in the legend, whereas what is plotted with rectangle will not be listed in the legend. So, the best one to use depends on what we want to do.
