I am trying to visualise data as a 3-D bar chart. I used "bar3" function.

How I can add text (the value) on the top of each chart?

I tried to write the following code, and it works well.

But I still need to add some text on the plot.

DATA_Sensitivity=[
72.71683742	46.68656078	52.79741961	52.20167451	50.83051373;
74.50372032	52.25829563	64.02911011	62.78763198	61.79562594;
63.10542986	50.6254902	56.6627451	53.09019608	52.96666667;
67.62513583	58.98431373	62.33590527	62.04112554	65.53002292;
79.37428385	53.68823529	62.44705882	67.95098039	64.88431373];
%% Sensitivity Bar Chart
figure
h = bar3(DATA_Sensitivity,'detached');
hh = get(h(3),'parent');
set(hh,'yticklabel',['PSD';'STD';'AM ';'SE ';'DE ']);
hhh = get(h(3),'parent');
set(hhh,'xticklabel',['ANN';'DT ';'LDA';'SVM';'KNN']);
ax = gca;
ax.YLabel.String = 'features';
ax.YLabel.FontSize = 16;
ax.XLabel.String = 'classfiers';
ax.XLabel.FontSize = 16;
ax.ZLabel.String = 'Sensitivity';
ax.ZLabel.FontSize = 16;
ax.Title.String = 'Avrage Sensitivity';
ax.Title.FontSize = 16;
zlim([0 100])

What will the labels be?

Have you looked at this answer yet?

Assuming your labels are numeric, here's how I'd do it using the code you've provided

[X,Y] = meshgrid(1:size(DATA_Sensitivity,2), 1:size(DATA_Sensitivity,1));
text(X(:), Y(:), DATA_Sensitivity(:), num2str(DATA_Sensitivity(:)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom')

Works for me in R2017a. I'm using the Windows install.

matrix=[0.9187  0.9534  0.9462 ; 0.9002  0.9199  0.8282 ; 0.9003  0.9175  0.8223 ; 0.9015  0.9141  0.8435;  0.9964  0.9332  0.4070];
figure
h = bar3(matrix,0.4,'detached');
 
set(h(1),'facecolor','c');
set(h(2),'facecolor','y');
set(h(3),'facecolor','green');
hh = get(h(3),'parent');
set(hh,'yticklabel',['WT/Ens_{2}' ,'GPR/Ens_2','Tree/Ens_2';'WT/Ens_{4}','GPR/Ens_4','Tree/Ens_4';'WT/Ens_{7}','GPR/Ens_7','Tree/Ens_7';'WT/Ens_{9}','GPR/Ens_9','Tree/Ens_9';'WT/Ens_{8}','GPR/Ens_8','Tree/Ens_8'],'fontweight','bold','FontSize',11,'YColor','b');
hhh = get(h(3),'parent');
set(hhh,'xticklabel',[{'WT/Ens'},{'GPR/Ens'},{' Tree/Ens'}],'fontweight','bold','FontSize',11,'XColor','b');
ax = gca;
ax.ZLabel.String = 'Value Correlation';
ax.ZLabel.FontSize = 12;
ax.ZLabel.Color='b';
ax.Title.String = 'Corr';
ax.Title.FontSize = 13;
ax.Title.Color='b';
[P,Z]=meshgrid(1:size(matrix,2),1:size(matrix,1));
text(P(:),Z(:),matrix(:), num2str(matrix(:)),'HorizontalAlignment','center','VerticalAlignment','bottom')

@Samir Gouin, adjust the FontSize property when using text.

matrix=[0.9187 0.9534 0.9462 ; 0.9002 0.9199 0.8282 ; 0.9003 0.9175 0.8223 ; 0.9015 0.9141 0.8435; 0.9964 0.9332 0.4070];

figure

h = bar3(matrix,0.4,'detached');

set(h(1),'facecolor','c');

set(h(2),'facecolor','y');

set(h(3),'facecolor','green');

hh = get(h(3),'parent');

set(hh,'yticklabel',['WT/Ens_{2}' ,'GPR/Ens_2','Tree/Ens_2';'WT/Ens_{4}','GPR/Ens_4','Tree/Ens_4';'WT/Ens_{7}','GPR/Ens_7','Tree/Ens_7';'WT/Ens_{9}','GPR/Ens_9','Tree/Ens_9';'WT/Ens_{8}','GPR/Ens_8','Tree/Ens_8'],'fontweight','bold','FontSize',11,'YColor','b');

hhh = get(h(3),'parent');

set(hhh,'xticklabel',[{'WT/Ens'},{'GPR/Ens'},{' Tree/Ens'}],'fontweight','bold','FontSize',11,'XColor','b');

ax = gca;

ax.ZLabel.String = 'Value Correlation';

ax.ZLabel.FontSize = 12;

ax.ZLabel.Color='b';

ax.Title.String = 'Corr';

ax.Title.FontSize = 13;

ax.Title.Color='b';

[P,Z]=meshgrid(1:size(matrix,2),1:size(matrix,1));

text(P(:),Z(:),matrix(:), num2str(matrix(:)),'HorizontalAlignment','center','VerticalAlignment','bottom',...

'FontSize',20)

Hi,

Thanks for the great answer above!

Is there any way to get more space between the different bars (Y,M,C,K)?

Thanks

There does not appear to be a property in bar3 that allows for adjusting the spacing in the y direction.

You can specify your inputs for y using the following syntax, but if the increment is uniform between the values, it always gets normalized back to looking exactly the same.

bar3(y,z)
