bar plot, value on top

Hi This actually works to some extent but the problem is i got all the values for each bar shown on top. So for each bar all the Y values are being shown.

x=[1:2:23]';
y=abs([121 41 20.6 12.5 8.1 5.8 4.4 3.5 3 2.7 2.3 2.1]);
bar(x,y)
text(x,y,num2str(y,'%0.2f'),...
    'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')

Please tell me what is wrong! Thanks!

Hi gabe, Can you please help me with displaying the value on top of bar plot.I am using GUI and my 7 different coloured bars are continuously changing with analog input so the value should also change continuously on top. I would really apreciate your answer.

[Elimelech Schreiber]

num2str(y,'%0.2f')

converts the numbers in y, into one long string, and therefor it's repeated above each bar.

you need to have a seperate string for each value. The easiest fix here woul be:

num2str(y','%0.2f')

[Andrei Bobrov]

x=[1:2:23]';
y=abs([121 41 20.6 12.5 8.1 5.8 4.4 3.5 3 2.7 2.3 2.1]);
bar(x,y)
for i1=1:numel(y)
    text(x(i1),y(i1),num2str(y(i1),'%0.2f'),...
               'HorizontalAlignment','center',...
               'VerticalAlignment','bottom')
end

[gabe]

works like a charm :) Thank you my friend!

[Oleg Komarov]

Or simply (no need for loop)

text(x,y',num2str(y','%0.2f'),...

'HorizontalAlignment','center',...

'VerticalAlignment','bottom')

Hi Andrei, Can you please help me with how can i add an arrow in bar plot which are 7 different colours bars.The arrow should be placed above each bar and it should be directed upward when coloured bar is increasing and downward when bar is decreasing continuously.Thanks!

[Arjun Chiddarwar]

What if I don't have an X axis data, I have data to be plotted on just the Y axes. Then?

Something like this -

Y=[198 138 172 188 190 192];
bar(Y);

Then?

[Javier Gonzalez-Rocha]

Try generating an arbitrary x array of length equal to y. Omit the x array in your plot using the gca handle as shown below:

    Y=[198 138 172 188 190 192];

    % arbitrary array
    X = 1:6;

    figure
    bar(X,Y);
    labels = arrayfun(@(value) num2str(value,'%2.2f'),Y,'UniformOutput',false);
    text(X,Y,labels,'HorizontalAlignment','center','VerticalAlignment','bottom') 

      % clears X axis data
      set(gca,'XTick',[]);

I've written a function to do just this. It's called barvalues, and is very easy yo use.

simply:

bar(x);
barvalues;

[Alexander Pakakis]

great work!!! How can I add a "%" to the back of the values?

[Elimelech Schreiber]

use the formatspec option:

 barvalues([],formatspec);

See formatspec in NUM2STR help

Example:

 x=[1:10;11:20;10:19;15:24]; 
 figure(123); 
 bar(x');
 barvalues([],'%.0f%%');

the last '%%' directs it to append an '%' at the end.

[Yasir Ali]

Hi @Elimelech Schreiber, I am using your barvalues function. It's working perfectly. However when i am trying to put different value on top of bar, it does not work. any help. I want to plot a bar chart having ids in different matrix

a= data(:,1); % first column of data matrix containing 13 values
b= data(:,2); %containing ids of each value
bar(a);
barvalues;

[Elimelech Schreiber]

i'm sorry, barvalues() is meant to be used for displaying bar values.

If you want to display additional id labels, i recommend using:

help xticks();
help xticklabels();

[Luis Fernando Marzola da Cunha]

Elimelech Schreiber thank you very much. This function is very useful. Congratulations.

[Giulia Grazioli]

Hi @Elimelech Schreiber, I was looking for a way to write the values with "%" sing on top a bar graph and i get into yuor comment with your function. It solved all my problems, so thank you so much!!

Can be a little cleaner than the above solutions, by making a cell array with the labels in advance using the arrayfun function.

x=[1:2:23]';
y=abs([121 41 20.6 12.5 8.1 5.8 4.4 3.5 3 2.7 2.3 2.1]);
bar(x,y)
labels = arrayfun(@(value) num2str(value,'%2.1f'),y,'UniformOutput',false);
text(x,y,labels,...
  'HorizontalAlignment','center',...
  'VerticalAlignment','bottom')

Please Try this code, Hope your problem will be solved. Best of luck

clc
clear all
close all


x = [1     2     3      4      5      6      7    8    9     10];
y = [200  250    300    350    400    450    500  550  600  700 ];  
 z= bar(x,y)
 for i1=1:numel(y)
    text(x(i1),y(i1),num2str(y(i1),'%0.0f'),...
               'HorizontalAlignment','center',...
               'VerticalAlignment','bottom')
end
% text(1,43,'42','Color','k','FontSize',9)
% plot(x,y, '->','LineWidth',2)
xlabel('Friends')
ylabel(' Record')
title('Friends List')
grid on
ax=gca;
ax.XTick = [1 2 3 4 5 6 7 8 9 10 ]; 
ax.XTickLabels = {'Junaid', ' Qadir' ,' Sahar ',' Ubaid ',' Munsif ',' Yousaf ',' Sami ','Najm',' Shakir', ' Pakistan'};
ax.XTickLabelRotation = 45;
z.FaceColor = 'flat';
% z.EdgeColor= '[1,0,0]';
 z.CData(1,:) = [1,1,0];
 z.CData(2,:) =  [1,1,0];
z.CData(3,:) =	[1,1,0];
z.CData(4,:) =	[1,1,0];
z.CData(5,:) =	[1,1,0];
z.CData(6,:) =	[1,1,0];
z.CData(7,:) =	[1,1,0];
z.CData(8,:) =	[1,1,0];
z.CData(9,:) = [1,1,0];

Dear bro, kindly give a code for the same process for a grouped bar diagram

[SOMNATH MAHATO]

x = [1 2 3 4 5];

y = [0.433 0.177 0.768 1.224; 0.379 0.158 0.267 0.320; 0.0406 0.016 0.031 0.0380; 0.0972 0.0371 0.0538 0.0483; 0.0777 0.0324 0.0552 0.0660];

x TickLabels ('xx', 'xy', 'aa', 'bb', 'cc')

How i can plot with this data? I want to plot like above figure.

[Tony Castillo]

x = [1 2 3 4 5];

y = [0.433 0.177 0.768 1.224; 0.379 0.158 0.267 0.320; 0.0406 0.016 0.031 0.0380; 0.0972 0.0371 0.0538 0.0483; 0.0777 0.0324 0.0552 0.0660];

bar(x,y)

ax=gca;

ax.XTick = [1 2 3 4 5];

ax.XTickLabels = {'xx', 'xy', 'aa', 'bb', 'cc'};

ax.XTickLabelRotation = 45;

Please try with this code

@Tony Castillo Good job, I appreciate your efforts.

x = [1 2 3 4 5];

bar(x,y)
ax=gca;
ax.XTick = [1 2 3 4 5]; 
ax.XTickLabels = {'xx', 'xy', 'aa', 'bb', 'cc'};
ax.XTickLabelRotation = 45;

[Tony Castillo]

Hi guys,

But despite I have tried to put the avlues on the TOP/OVER every one bar, I could not, even in the code I already change botton for cap, but it has been unsuccesfull.

Could you help me to set the values on the peak of every one bar?.

The code is attached.

Thanks
