Hi,
How can I perform such task concering iris dataset?
Now plot histograms of all variables coloring them by species. Use hold on to overlay plots for different datasets on one figure. Which variables separate species well?
Thanks

Walter gives a simple example below. If you want a quick introduction to plotting in MATLAB, consider going through Ch 9 of MATLAB Onramp. It doesn't cover histograms specifically, but does show you how to call plotting functions, including adding multiple plots to the same axes. It should take about 10-15 mins to complete.
If you find that helpful, you might consider going through some of the other chapters as well. Is a nice, free way to learn the fundamentals of MATLAB.

Ran in:
x1 = rand(1,100);
x2 = rand(1,100).^2 + 0.1;
x3 = exp(rand(1,100));
histogram(x1);
hold on
histogram(x2);
histogram(x3);
hold off
legend({'x1', 'x2', 'x3'})
