How to link subgroup data points together in a plot?
显示 更早的评论
I have matrix A like the below. The first column is the group number.
% GroupNo, X, Y
1, x1, y1
1, x2, y2
1, x3, y3
2, x4, y4
2, x5, y5
It's very important I plot them together like the below:
h = plot(A(:,2), A(:,3),'ro');
My question is how do I link all the data points in Group 1, Group 2, ..., respectively? I could have unknow number of groups.
When I say "link", I mean, to plot using "o-", instead of "o'.
Thanks

What about this?
hold on
A1 = unique(A(:,1));
cmark = {'o' '*' '.'};
for i = 1:numel(A1)
ix = A(:,1)==A1(i);
h(i) = plot(A(ix,2),A(ix,3),...
'marker',cmark{randi(3,1)},...
'color',rand(1,3));
end
