MULTIPLOTYYY allows the user to plot multiple lines on three sets of y-axes.

| Watch this File

File Information

MULTIPLOTYYY plots using three sets of y-axes values. Additionally, multiple lines can be plotted against each y-axis. Therefore, the inputs to the function must be grouped into cell arrays.
Here is an example call to the function:
x1 = (0:0.01:1)';
x2 = (0:0.1:1)';
x3 = (0:0.05:1)';
y1 = x1;
y2 = x2.^2;
y3 = x3.^3;
y4 = sin(x1);
y5 = fliplr(2*x1.^2);
y6 = 7*cos(x1);
y7 = 7*log(x1+1.2);
ylabels{1}='First y-label';
ylabels{2}='Second y-label';
ylabels{3}='Third y-label';
[ax,hlines] = multiplotyyy({x1,y1,x2,y2,x3,y3,x1,y4},{x1,y5},{x1,[y6,y7]},ylabels);legend(cat(1,hlines{:}),'a','b','c','d','e','f','g','location','w')

Great function! I needed to plot Power and Thrust curves of a wind-turbine for a college work, and multiplotyyy worked perfectly.

Thank you very much! I'll make sure you appear on the acknowledgements.

Andreas, all the lines are saved in the output, hlines. You can change the style using these. Or, you can change it in the code. If you let me know what you're looking for, I can help out.

To work with the legend, you can use the following modifications after you call the code that will align the axes with a legend on the left hand side. Please feel free to contact me directly, I'd be happy to help!

>> leg = legend(cat(1,hlines{:}),'a','b','c','d','e','f','g','location','w');
>> leg.Location = 'westoutside';
>> ax(2).Position = ax(1).Position;
>> ax(3).Position = ax(1).Position;
>> offset = 0.7/5.5;
>> ax(3).Position(3) = ax(3).Position(3) + offset;
>> ax(3).XLim = [ ax(1).XLim(1) ax(1).XLim(2)*(1 + 1/(ax(1).Position(3)) * offset)];

Great tool!! Is there a way to change the linestyle?

The only problem is, that the 2nd & 3rd axis are messed up when I put the legend outside of the plot. Can anybody help me with this? When I plot multiple lines it's confusing with the legend inside the plot. Thanks!

when I run the example it shows me that: Undefined function 'multiplotyyy' for input arguments of type 'cell'
what is it wrong then? thanks!

Couple of mistakes in the example, but otherwise works as advertised, thanks!

I fixed the mistakes in the original example call.
