labeling bar graphs ?

Juliette Salexa — Thu, 02 Jul 2009 22:05:03 -0400

If I have an array of values called A,
and I apply the command bar(A), I get a bunch of rectangles showing me the contents of A.

Say I had another array B, who's elements were strings which I intend to use to label each of the the rectangles corresponding to the elements of A. How can I get these strings to show up as labels for the rectangles in the bar graph, from the command line ??
it should only be one command .. I shouldn't have to add them manually.

well...
How about
A = rand(5,1);
B = {'One';'Two';'Three';'Four';'Five'};
bar(A);
set(gca,'XTickLabel',B);

(The set(gca,'XTickLabel',label) is your "one command")
I hope that's what you were looking for...

I knew how to do that, although not so elegantly!
But I actually meant to have the labels on the graph itself, which I think the only way to do is manually .. although I hope there is a way!
