Hello every one,

Please I have question I could not figure. I have a plot of two curves and I want to show the improvement obtained by the second curve. In other words, for example if the first curve has a datum of 60 and the second one has corresponding datum of 75, that means improvement 25%. Is there any way to show this number (25%) close to this datum on the plot programatically or manually from the plot.

Thanks in advance

You could simply put a text label next or close to a data point:

text(x_pos,y_pos,text_lab)

where x_pos and y_pos are the coordinates of the text box. text_lab is a string that you could put together from your measurement data (using num2str).

Thank you Mischa, That exactly what i want, however the data are overlapping because I have 4 curves. I just illustrate one data from each ten. Is there any way to have these data in a box like the legend but close to the data, also can I insert % symbol to this function. I am sending you a photo of the curve. The function I wrot is: text(U_R(1:10:end,i+1),R(1:10:end),num2str(U_percent(1:10:end,i+1)));

Hi

I try to label my points. I just modified Abdulaziz code for my 3-D plot. But it is not working to me! Here, the labeling string(number) vary everytime when I run the code. Can any body help me!

The modified code is given below. text(X(1:end,i+1),Y(1:end),Z(1:end),num2str(N_chain(1:end,i+1)));

Attachment:

Non_Labeled - It just provided to view the clear graph.
Labeled - It is the out that I am getting for above code. It means entire set of labels(strings) are appearing at the same time in each node. I need to display it separately to understand position.

Can anybody help me to get the same
