MATLAB: Using Multiple X- and Y-Axes Command Axis Label

plotyy

figure (9)

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('Drag Force (lbf.)') xlabel('Time (s)')

The above only labels the top axis and the right axis. How do I label the left and the bottom axis?

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)')

MATLAB: Are the rightmost axes from two or more subplots not aligned when creating the subplots with y-axes on the right and left hand side

This is expected behavior when adding a second axes on a subplot figure. The plot boxes can be lined up using the 'align' option in the SUBPLOT function. To do this, change

subplot(2,2,1)

subplot(2,2,1,'align')

For example,

x1 = 1:100; y1 = x1*ones(length(x1)); 
x2 = 1:100; y2 = cos(pi*x2/6); 
subplot(2,2,1,'align') 
plot(x1,y1,'Color','r'); 
set(gca,'XColor','r','YColor','r'); 
axes('Position',get(gca,'Position'), 'XAxisLocation','top',... 
      'YAxisLocation','right','Color','none', 'XColor','k','YColor','k'); 
hold on; 
plot(x2,y2,'Color','k'); 
subplot(2,2,2,'align') 
plot(x1,y1,'Color','r'); 
set(gca,'XColor','r','YColor','r'); 
axes('Position',get(gca,'Position'), 'XAxisLocation','top',... 
      'YAxisLocation','right','Color','none', 'XColor','k','YColor','k'); 
hold on; 
plot(x2,y2,'Color','k'); 
subplot(2,2,3,'align') 
plot(x1,y1,'Color','r'); 
set(gca,'XColor','r','YColor','r'); 
axes('Position',get(gca,'Position'), 'XAxisLocation','top',... 
      'YAxisLocation','right','Color','none', 'XColor','k','YColor','k'); 
hold on; 
plot(x2,y2,'Color','k'); 
subplot(2,2,4,'align') 
plot(x1,y1,'Color','r'); 
set(gca,'XColor','r','YColor','r'); 
axes('Position',get(gca,'Position'), 'XAxisLocation','top',... 
      'YAxisLocation','right','Color','none', 'XColor','k','YColor','k'); 
hold on; 
plot(x2,y2,'Color','k');

MATLAB: Plotting using multiple x-axes and y-axes.

...
ax1_pos=set(ax1,'Position');
ax2 = axes('Position',ax1_pos,...

ax1_pos will be empty after the above; you (probably inadvertendtly) typed set instead of get.

Try

    ax1_pos=get(ax1,'Position');

instead.
