How to plot data in vertical lines
显示 更早的评论
I want to produce a plot like the one drawn below:
Where I have two values of y for each value of x:
x=[1 2 3 4]
y1=[3 2 3 1]
y2=[4 6 7 3]
What is the best strategy to accomplish this?
Right now I believe the only way to achieve this result by doing something like the folowing piece of code.
However this is not pratical, and I'll have to write some more code, including some for loops, to deal with the original data. Costumizing all the line properties seems a painfull task as well.
plot([1 1],[3 4 ])
hold on
plot([2 2],[2,6])
plot([3 3],[3,7])
plot([4 4],[1,3])
xlim([0,5])

You can use for loop. The colors of the line will be chosen at random, so there's a chance they might be similar or overlap with each other.
x=[1 2 3 4];
y1=[3 2 3 1];
y2=[4 6 7 3];
y=[y1;y2]';
for i=1:numel(x)
plot([x(i) x(i)],y(i,:),'o-')
hold on
end
xlim([0 5])
ylim([0 8])

Why not? It can certainly be shortened from what you have, though:
x=[1 2 3 4];
y1=[3 2 3 1];
y2=[4 6 7 3];
h=plot([x;x],[y1;y2]); axis padded
set(h,'Marker','o')

Use the line handles:
x=[1 2 3 4];
y1=[3 2 3 1];
y2=[4 6 7 3];
lengths=y2-y1;
h=plot([x;x],[y1;y2],'-o'); axis padded
set(h(lengths>2),'Color','green')
set(h(lengths<=2),'Color','red')
