bar graph of separate columns from different data sets

Hello everyone! I have this problem, I need to upload data from 3 different files and create a single bar for all. What I have got so far is:

path='C:\nath\bars';
eval(['load ' path '\bar1.mat']);
figure
figure1=bar(dist, 'histc');
set(figure1,'FaceColor','g')
hold all
eval(['load ' path '\bar2.mat']);
figure2=bar(dist, 'histc');
set(figure2,'FaceColor','r')
hold all
eval(['load ' path '\bar3.mat']);
figure3=bar(dist, 'histc');
set(figure3,'FaceColor','b')

That gives me a graph where the columns overlap. Is it possible to separate them so that for each bin I have 3 different columns?

Thank you in advance!

Attach a screenshot so we can see what you're talking about. While you're at it, attach your .mat files also. And change this

path='C:\nath\bars';
eval(['load ' path '\bar3.mat']);

to this

folder ='C:\nath\bars';
fullFileName = fullfile(folder, '\bar3.mat');
load(fullFileName);

path is a reserved word in the MATLAB language so you don't want to redefine it.

thank you for your answer! and you are right! so this is how it looks like:

and I want for example for the bin 0-3.5 to have 3 different columns.

Then I followed your advice and did

 folder ='C:\nath\bars';
fullFileName = dir(fullfile(folder, '*.mat'));

so that it loads all files

and did a loop for f = 1:length(fullFileName) create the graph but again I dont know what to do after!
