Problem with axes in 4 axis plot

Im currently trying to plot 4 variables (one on each axis) that sum to 100. However in plotting the second set of axes at the top and right, the scatter plot seems to go astray.

if true
scatter(x1,y1,1,C)
ax1=gca;
ax1_pos = ax1.Position; % position of first axes
ax2 = axes('Position',ax1_pos,...
  'XAxisLocation','top',...
  'YAxisLocation','right',...
  'Color','none');
ax2=gca;
scatter(x2,y2,1,C)

end

Thank you in advance

You should pass the axes to the scatter function explcitly rather than just having it plot on the current axes. e.g

scatter( ax1, x1, y1, 1, C );

after creating ax1.

Creating ax2 and then overwriting the ax2 variable with gca is also not a good idea. At best it is redundant since the aim is to assign to ax2 the value that it already contains.

Hey Adam, Thanks for the speedy reply. I tried something like this before and still couldn't get it to work. I though that using gca might change the axes handle.

if true
  % code
end
ax1=gca;
ax1_pos = ax1.Position; % position of first axes
scatter(ax1,x1,y1,1,C)
ax2 = axes('Position',ax1_pos,...
  'XAxisLocation','top',...
  'YAxisLocation','right',...
  'Color','none');
scatter(ax2,x2,y2,1,C)

And what is the result? What aspect of it doesn't work?

Its plotting both axes to the same x and y. I specified it like that originally then started using the gca.
