Thread Subject:

bar graphs with string labels?

I have a set of concentration data C for a number of chemical species.
I want to make a bar graph where each of the bars is evenly spaced
and the bars have text labels as to what compound they refer to. Is
this possible?

bar(C) generates a bar graph but labels the bars with their index
number. Is there a way to turn this off? If I say axis off then
there are no axes at all, including the y-axis, tic marks, etc.

bar(compds,C) where compds is a string vector of compound names,
generates an error: X must be a vector.

I feel that this must be possible, since it certainly isn't
complicated. I would be grateful for any suggestions.

Try typing BENCH, and look at the final output (bar graph). Is this
what you want?

Yes, it is. I will study this example and see if I can adapt it to my
case.

Thanks!

No need to study. The answer lies on line 229

set(gca,'yticklabel',specs)

"specs" is a cellstr array of machine names. The author (Dr. Moler,
himself?) replaces the numerical labels with the machine names using the
above command.

Chris,

Just use the BAR command in the normal way, and then replace the
XTickLabels. Here is some sample code:

   x = rand(4,1);
   bar(x);
   Labels = {'a', 'b', 'c', 'd'};
   set(gca, 'XTick', 1:4, 'XTickLabel', Labels);

Hope that helped,

Jordan
