Help with this code

I am trying to plot one X axis and 3 Y axes by using plotyyy and my code is:

      Tdata = [4 .6458 8 6.2;
               5 .3324 13 6.7;
               6 .2661 14 6.6;
               7 .2216 16.5 5.6;
               8 .2426 16.5 6.2;
               9 .3554 13 6.5;
               10 .4814 8.5 6.2];

      x = Tdata(:,1);
      y1 = Tdata(:,2);
      y2  = Tdata(:,3);
      y3  = Tdata(:,4);

      [ax,h1,h2,h3] = plotyyy (x,y1,x,y2,x,y3,'bar','plot','plot')

But, I am getting this error

Error in Two_Y_Axes_Plot_2 (line 22) [ax,h1,h2,h3] = plotyyy (x,y1,x,y2,x,y3,'bar','plot','plot')

Can someone help PLEASE

What did the error message say?

[Matt Tearle]

plotyyy is not a built-in MATLAB function. Can you provide the code or the link to where it came from (File Exchange, I'm guessing)?

Tdata = [4 .6458 8 6.2;
         5 .3324 13 6.7;
         6 .2661 14 6.6;
         7 .2216 16.5 5.6;
         8 .2426 16.5 6.2;
         9 .3554 13 6.5;
         10 .4814 8.5 6.2];
x = Tdata(:,1);
y1 = Tdata(:,2);
y2  = Tdata(:,3);
y3  = Tdata(:,4);
plot(x,y1,x,y2,x,y3)

good luck

or this one:

Tdata = [4 .6458 8 6.2;
           5 .3324 13 6.7;
           6 .2661 14 6.6;
           7 .2216 16.5 5.6;
           8 .2426 16.5 6.2;
           9 .3554 13 6.5;
           10 .4814 8.5 6.2];
  x = Tdata(:,1);
  y1 = Tdata(:,2);
  y2  = Tdata(:,3);
  y3  = Tdata(:,4);
  subplot(3,1,1)
  plot(x,y1)
  subplot(3,1,2)
  plot(x,y2)
  subplot(3,1,3)
  plot(x,y3)

good luck

I'd like to have three y axes in the graph besides the data
