multiple y axes, one x axis

Hello, I want to know how to do three y axis one next to one on left side with space.. My function and i want it that is everything on left side on y axis.

clc
clear all
close all
x=[5.93 5.65 4.91 4.28 3.77 3.25];
y1=[10.72 10.15 8.76 7.61 6.68 5.76];
y2=[62.5 50 41.25 31.25 25 17.5];
y3=[4.661 4.413 3.809 3.309 2.904 2.504];

figure;
ax1 = gca;
get(ax1,'Position')
pos_ax1 = get(ax1,'Position'); 
set(ax1,'XColor','k',...
  'YColor','b',...
  'YLim',[0,12],...
  'YTick',[0:1:12]);
ylabel('U_1_K [V]')
xlabel('I_1_K [A]')
line(x, y1, 'Color', 'b', 'LineStyle', '-', 'Marker', '.', 'Parent', ax1)
grid on

ax2 = axes('Position',get(ax1,'Position'),...
         'XAxisLocation','bottom',...
         'YAxisLocation','left',...
         'Color','none',...
         'XColor','k',...
         'YColor','r',...
         'YLim',[0,70],...
         'YTick',[0:5:70],...
         'XTick',[],'XTickLabel',[]);
     ylabel('P_1_K [W]')
 pos_ax2=pos_ax1-1;
line(x, y2, 'Color', 'r', 'LineStyle', '-', 'Marker', '.', 'Parent', ax2)

ax3 = axes('Position',get(ax1,'Position'),...
         'XAxisLocation','bottom',...
         'YAxisLocation','right',...
         'Color','none',...
         'XColor','k',...
         'YColor','magenta',...
         'YLim',[0,5],...
         'YTick',[0:0.5:5],...
         'XTick',[],'XTickLabel',[]);
     ylabel('u_K [%]')
line(x, y3, 'Color', 'g', 'LineStyle', '-', 'Marker', '.', 'Parent', ax3)
title('Prikaz merilnih rezultatov')

%figure 2

I_n = 5.435;
U_1_k=interp1(x,y1,I_n)
P_1_k=interp1(x,y2,I_n)

Thanks :)

Thanks for that but i just can't get them one next to another..This figure I get:

[androSLO]

I get with your code just one line with yours functions.. I had given up about this cause i am sitting in front of computer for 3 hours almost to get this to work it but no success..Only problem is just this y scale which can't i get one by one on side..

[Azzi Abdelmalek]

Have you tested my code with my data, if yes try to adapt your data to my code

[androSLO]

I copied your code into matlab in this is the result:

[Azzi Abdelmalek]

You are right, this is because I used in my code a function named decimal, I removed it, look at edited answer

[androSLO]

Yes i figure it out everything now :) Finished :)Here is result:

Thank you all for help :)

[Carlos Quispe Galdos]

This is extremely clever! thank you

Adapt this code supplied by the Laura at Mathworks: http://www.mathworks.com/matlabcentral/fileexchange/39595-multiplotyyy

androSLO commented

Where to adapt this code into it cause it doesn't work..

[Azzi Abdelmalek]

androSLO, I've deleted your answer, and posted it above, because it's supposed to be a comment, not an answer. To add a comment just click on: comment on this answer

[androSLO]

Ok, I am sorry. But can somebody tell me where to put that code into it that it will work?

[Image Analyst]

Put it there somewhere between the first line and the last line. I think you're a smart enough engineer to figure it out. Sorry but I don't know the details of her code, and don't have the time to do it all for you.
