What would the bar graph coding be?

Histo1 is a 6 column data. When click on bar graph (the image attached is displayed). How can I code it to also include text for each group of bars?

I am not certain what you want, so here are two possibilities:

D = load('histo1.mat');
histo1 = D.histo1;

figure(1)
bar(histo1);
set(gca, 'XTickLabel', {'Group 1', 'Group 2', 'Group 3', 'Group 4', 'Group 5', 'Group 6'})

figure(2)
bar(histo1);
legend('Group 1', 'Group 2', 'Group 3', 'Group 4', 'Group 5', 'Group 6')

Be sure to look at both figures! The code in each labels the ‘group’ data differently.

The first is good for me but how do I inclined the groups?

Do you want the labels at an angle to the horizontal? If you have R2014b or later, this is relatively easy. If you have an earlier version, it is still possible but more difficult.

The R2014b and later code:

D = load('AbelM Kusemererwa histo1.mat');
histo1 = D.histo1;

figure(1)
bar(histo1);
set(gca, 'XTickLabel', {'Group 1', 'Group 2', 'Group 3', 'Group 4', 'Group 5', 'Group 6'}, 'XTickLabelRotation',30)

The rotation is in degrees, so experiment with it to get the result you want.
