Hi, I want to fill with light gray shadow (how to control the color?) between my two vertical line, xline(1), xline(10), the height is just consisent with the figure. and I don't want legend for xline(1) and xline(10) Thank you
figure
le=[1,2,3];
x=[0 5 15];
y=2*x;
for i =1 : length(x)
txt = ['$\alpha_1$ = ',num2str(le(1,i))];
plot(x, y, '-+','LineWidth',1.5,'DisplayName',txt);
hold on
end
legend('Location','best','Interpreter','latex','FontSize',16)
legend show
legend boxoff
hold on
xline(1)
xline(10)
grid on
set(gca,'fontweight','bold','FontSize',20)

figure
le=[1,2,3];
x=[0 5 15];
y=2*x;
for i =1 : length(x)
txt = ['$\alpha_1$ = ',num2str(le(1,i))];
hp1{i} = plot(x, y, '-+','LineWidth',1.5,'DisplayName',txt);
hold on
end
hold on
xlinelocs = [1 10];
hxl = xline(xlinelocs);
hp2 = patch([xlinelocs flip(xlinelocs)], [[1 1]*min(ylim) [1 1]*max(ylim)], 'b', 'FaceAlpha',0.25);
hp2.FaceColor = [1 1 1]*0.75;
grid on
set(gca,'fontweight','bold','FontSize',20)
legend([hp1{:}],'Location','best','Interpreter','latex','FontSize',16)
legend show
legend boxoff
Add or modify the patch parameters to get the desired result.
EDIT — Repositioned the legend call.

The patch call should work, regardless of what else is plotted with it.
I do not understand the problem you are having with it, and what needs to be fixed.
Please post your code and how you want the plot to appear.
