How to plot vertical lines for each data point?

I have a line graph plot which is giving me a correct figure looking like the following:

However, my task is to recreate a zonation simulating the following figure:

I therefore need to add vertical lines to the plot at each data point along the x axis.

Any help would be greatly appreciated.

Combine a plot plot (or a line plot) and a stem plot.

x = 0:10;
y = x.^2;
plot(x, y);
hold on;
stem(x, y, 'Marker', 'none');

Thank you Steven, this works great!

Check this example

% Example data
x = logspace(0,1,30);
y = log(x);

% plot original line
plot(x,y);
hold on;

% plot vertical lines
line_coordinates = [x' x' zeros(size(x')) y'];
line_coordinates = mat2cell(line_coordinates, ones(numel(x),1), [2 2])';
line_coordinates(3,:) = {'k'};
plot(line_coordinates{:})

My x axis is not consistantly placed

I have 10 data points on the x axis which are as follows:

950:983:1002:1004:1031:1047:1077:1098:1127:1160

So I tried to adapt your suggested code to account for this by replacing the x with my xplot and the y with my y plot. This has not worked and I'm unsure what else to try. Do you have any more suggestions?

Check Steven's answer. It mentions a cleaner solution.
