Do floating bar graphs exist in matlab?

问题

I'm trying to make a simple bar graph that would essentially look like the following horrible ASCII rendering:

Y
| ----------
|     ---
|         -----
| --
| -------
|______________ X
  5  6  7  8 9

Is this possible? I haven't found a way to do it.

回答1:

If you know exactly the coordinates of the desired bars in the graph, and the width of each bar line, you can do somthing like that:

a=[5 10; 5 23; 7 13; 6 18];      % each pair is a start point of bar 
L=0.1;                           %Bar width

for i=1:size(a,1)
    plot([a(i,1) a(i,1)+L], [a(i,2) a(i,2)])
    hold on
    ylim([ 9 24])
end

where in a you put the coordinates, and L is the bar length.
