How do I make line stacked graph like this?

Hello,

I have a question regrading this graph.

I just made this graph in the EXCEL that x axis is angle(0 to 90 degree) and time(sec).

However, it is very time-cusming process, because, I have to assign single time into a single series like in the graph.

So, I want to make like this graph in the MATLAB.

It's actually stacking x=const lines in time.

When I put starting angle and ending angle in all time, I want to plot line stacked graph like in the above.

How do I make it?

Thanks,

Hyojae.

Hi, its much easier if you would provide the numerical data as numerical data and not a screenshot ;)

Anyhow, yes such a plot can be made quite simple in matlab. First let's type over your data

data = [ 80 20;
    80 30;
    100 10;
    100 30;
    120 20;
    120 40;
    140 30;
    140 50;
    160 40;
    160 70];

One way to achieve this is by using a for loop. Note that it is also possible with a single call to the plot command by introducing nan in between the line's:

figure
hold on
for i = 1:2:size(data,1)
    plot(data(i:i+1,2),data(i:i+1,1),'-o','LineWidth',1.5)
end
xlim([0 80])
ylim([0 180])
hold off
grid on

Highly appreciated, Karim.

It helps me a lot!

Here's how you can do it with one plot call creating multiple lines:

data = [ ...
    80 20;
    80 30;
    100 10;
    100 30;
    120 20;
    120 40;
    140 30;
    140 50;
    160 40;
    160 70];

x = reshape(data(:,2),2,[]);
y = reshape(data(:,1),2,[]);
plot(x,y,'-o')

xlim([0 80])
ylim([0 180])
grid on
