MATLAB: Connect scatter line in multiple y axis

lineplotyyscatter

I have two y axis and one x axis plot.

    x=[0.8,1.3,2.2,2.9,3.6];
    y1=[17.22,18.9,19.74756674,21.64790459,22.77216041];
    y2=[0.07,0.11,0.163,0.27,0.29];
    [ax, h1, h2] = plotyy(x,y1,x,y2,'scatter');
    line(x,y1)
    set(ax(1),'ycolor','r') 
    set(ax(2),'ycolor','b')

It connected the first scatter lines. But i cant conned the second scatter lines. Please help?

Add this line to the code

    line( x, y2, 'Parent', ax(2) )

plotyy adds two axes on top of each other with ax(2) on top. Don't ask me why, but this line of code seems to add a visible line object. (I look forward to HG2.)

Use the ploty4 version attached. I have modified it to do what you want. You can use it like this:

h1 = subplot(2,1,1);
x = 0:10;
y1=x; y2=x.^2; y3=x.^3; y4=x.^4;
[ax,hlines] = plotyyyy(h1,x,y1,x,y2,x,y3,x,y4);
h2 = subplot(2,1,2);
x = 0:10;
y1=x; y2=x.^2; y3=x.^3; y4=x.^4;
[ax,hlines] = plotyyyy(h2,x,y1,x,y2,x,y3,x,y4);

my output:

ax1 = gca;
hl1 = line(x1,y1,'Color','r');
set(ax1,'XColor','r','YColor','r')
ax2 = axes('Position',get(ax1,'Position'),'XAxisLocation','top',... 
  'YAxisLocation','right','Color','none','XColor','k','YColor','k'); 
hl2 = line(x2,y2,'Color','k','Parent',ax2);
ylabel(ax1,'Drag Force (lbf.)')% do the same with ax2 
xlabel(ax1,'Time (s)')
