Hello!
I'm asking if it is possible to insert data in matlab and use them to plot histogram with different colors?
i have already used excel but i need a different form of histogram (bar forms), for example the first bar contains circles, the second contains squares,...
here is my data
Value first Second third
10 0,67 0,66 0,70
20 0,38 0,37 0,42
30 0,26 0,25 0,30
40 0,19 0,19 0,24
50 0,15 0,15 0,21
i need to see "first", "second" and "third" as function of value
Thanks in advance

Yes, one set of bars will be generated for each column of data, each with a different color.
data = randn(1000,3)+[-2 2 5];
hold on
histogram(data(:,1))
histogram(data(:,2))
histogram(data(:,3))

Not sure what this means, please elaborate or show us an image.

% Value first Second third
M = [ ...
10 0.67 0.66 0.70; ...
20 0.38 0.37 0.42; ...
30 0.26 0.25 0.30; ...
40 0.19 0.19 0.24; ...
50 0.15 0.15 0.21; ...
];
bar(M(:,1),M(:,2:end))

Look into the hatchfill2 function on the File Exchange in the link shared by VBBV.

Check the answer from the below link
May be its hatch property of the bar which should be used. It seems this is not default Matlab property for bar & histogram functions. You need to use the below custom function available from File Exchange.
