How can I title my bar graph in x-axis?

Hey,

As you know the default for x-axis in the Bar graph is just numbers. Could you please give me a hint how I can replace them by names? e.g. I would like to have a bar graph with the names of months (Jan, Feb, Mar, ...)in the x-axis.

Thank you,

Mehdi

I have no idea why. This code should work:

figure
name = {'m1';'m2';'m3';'m4';'m5'};
x = [1:5]; y = [19,24,42,12,14]; 
bar(x,y)
set(gca,'xticklabel',name)

Hi Grzegorz Knor, how could i name the xbars in a sequence.. for example to have numbers from 1:1:10.

bar(1:12)
set(gca,'xticklabel',{'a','b','c','d','e','f','g','h','i','j','k','l'})

Thank you Grzegorz, At the moment I have a cell array containing names:

fname = {'m1','m2','m3','m4','m5'};

and when I name them in the x-axis as you mentioned:

x = [1:5]; y = [19,24,42,12,14]; name = [fanme];

bar(x,y)

set(gca,'xticktlabel',name)

each of columns are named as m1m2m3m4m5

How can I have m1 for column1, m2 for column2 and so on?

Your problem can be solved like this:

fname = {'m1','m2','m3','m4','m5'}; 
x = [1:5]; y = [19,24,42,12,14]; 
bar(x,y)
set(gca, 'XTick', 1:length(fname),'XTickLabel',fname);

dt = 0.01; % Time step for numerical approximation tx = 0 : dt : 10; th = 3 : dt : 12; x = cos(pi * tx / 2); h = sin(pi * th); % Perform convolution and scale by dt y = conv(x, h) * dt; % Generate the time axis for the output ty = tx(1) + th(1) : dt : tx(end) + th(end); % Plotting figure; subplot(3,1,1); plot(tx, x); title('x(t)'); grid on; subplot(3,1,2); plot(th, h); title('h(t)'); grid on; subplot(3,1,3); plot(ty, y); title('Convolution y(t) = x(t) * h(t)'); xlabel('Time (t)'); ylabel('y(t)'); grid on;
