Good Day ,
Please assist me on these problems
1. I wish to put six plots on the same plot using matlab. The details of each plot are stated below
PLOT 1 x axis range 0:1 y axis range 0:1
PLOT 2 x axis range 0:1 y axis range 0:1
PLOT 3 x axis range 0:1 y axis range 0:1
PLOT 4 x axis range 0:1 y axis range 0:1
PLOT 5 x axis range 0:1 y axis range 0:2
PLOT 6 x axis range 0:1 y axis range 0:7
Please how do I put all these plots on one single plot despite different y axis range?
Thanks
Best regards, Isa

The issue is that this function can only plot one line per set of axes - so only three lines.
I have hacked Denis Gilbert's plotyyy code to facilitate your specific needs. See below:
%%Dummy data
x1 = 0:0.01:1;
x2 = x1;
x3 = x1;
x4 = x1;
x5 = x1;
x6 = x1;
y1 = x1;
y2 = x2.^2;
y3 = x3.^3;
y4 = sin(x4);
y5 = fliplr(2*x5.^2);
y6 = 7*x6;
ylabels{1}='A'; ylabels{2}='B'; ylabels{3}='C';
fh = figure('units','normalized');
cfig = get(fh,'Color');
ah(1) = axes('Parent',fh);
lh1 = plot(x1,y1,x2,y2,x3,y3,x4,y4);
lineColors = get(ah(1),'ColorOrder')
ah(2) = axes('Parent',fh);
lh2 = plot(x5,y5,'Color',lineColors(5,:));
set(ah(2),'YAxisLocation','right','Color','none');
pos = [0.1 0.1 0.7 0.8];
offset = pos(3)/5.5;
%Reduce width of the two axes generated by plotyy
pos(3) = pos(3) - offset/2;
set(ah,'position',pos);
%Determine the position of the third axes
pos3=[pos(1) pos(2) pos(3)+offset pos(4)];
%Determine the proper x-limits for the third axes
limx1=get(ah(1),'xlim');
limx3=[limx1(1) limx1(1) + 1.2*(limx1(2)-limx1(1))];
ah(3)=axes('Position',pos3,'box','off',...
'Color','none','XColor','k','YColor',lineColors(6,:),...
'xtick',[],'xlim',limx3,'yaxislocation','right');
lh3 = line(x6,y6,'Color',lineColors(6,:),'Parent',ah(3));
limy3=get(ah(3),'YLim');
%Hide unwanted portion of the x-axis line that lies
%between the end of the second and third axes
line([limx1(2) limx3(2)],[limy3(1) limy3(1)],...
'Color',cfig,'Parent',ah(3),'Clipping','off');
axes(ah(2))
%Label all three y-axes
set(get(ah(1),'ylabel'),'string',ylabels{1})
set(get(ah(2),'ylabel'),'string',ylabels{2})
set(get(ah(3),'ylabel'),'string',ylabels{3})

Hi, Laura I've been trying to adapt your code to my data, but I'm having a message of error, could you help me with it?.
I attached the data I'm actually using to graph it.

Tony Castillo: what error message do you observe?
Note: you omitted attaching the data.

Hi Walter,
Thanks. I used plotyyy as advised
ylabels{1}='A';
ylabels{2}='B';
ylabels{3}='C';
[ax,hlines] = plotyyy(x1,y1,x2,y2,x3,y3,x4,y4,x5,y5,x6,y6,ylabels)
I received the following error message
Error using plotyyy
Too many input arguments.
I cannot figure out what went wrong. Please assist.
Thanks
Isa
