MATLAB: How to plot vertical lines

linevertical line

This is the script:

x=[0:0.1:10]; x1=5;

plot(x,2*sin(x),x,5*sin(x),x,cos(x));

line([x1 x1],???????);

I would like to plot the vertical line from the top to the bottom without knowing the y-axis limits.

Thanks in advance!

x=[0:0.1:10];
x1=5;
plot(x,2*sin(x),x,5*sin(x),x,cos(x));
y1=get(gca,'ylim')
hold on
plot([x1 x1],y1)

Add these lines:

xa = linspace(0.14, 0.2, 25);                               % Define ‘x’ For ‘patch’

ya = normpdf(xa,.1,.02);                                    % Define ‘y’ For ‘patch’

patch([xa fliplr(xa)], [zeros(size(ya)) fliplr(ya)], 'r')

so the compllete revised code is now:

x = [0:.001:.2];
y = normpdf(x,.1,.02);
subplot(211)
plot(x,y,'linewidth',2);grid;box on;
hold on
YL = get(gca, 'ylim');
YR = YL(2) - YL(1);
YL = [YL(1) - 1000 * YR, YL(2) + 1000 * YR];
line([.14 .14], YL, 'YLimInclude', 'off', 'linewidth', 2, 'Color', ...
    'black','LineStyle','-.');
xa = linspace(0.14, 0.2, 25);                               % Define ‘x’ For ‘patch’
ya = normpdf(xa,.1,.02);                                    % Define ‘y’ For ‘patch’
patch([xa fliplr(xa)], [zeros(size(ya)) fliplr(ya)], 'r')
hold off

That should do what you want.
