Hi,

Im trying to move the axes of my isosurface plot so that they all intersect at the origin of the coordinate system.

I've tried using

ax = gca
ax.XAxisLocation = 'origin' 
ax.YAxisLocation = 'origin'

but this does nothing.

Are these even the right commands to use?

I've attached an image of my plot, i'll upload an MWE if necessary.

Thanks!

What you try would be worked in 2D.

plot(-1:0.1:1,(-1:0.1:1).^2)
axis equal
xlabel('x');ylabel('y');
ax=gca
ax.YAxisLocation
pause(3)
ax.YAxisLocation='origin'
pause(3)
ax.YAxisLocation='right'
hold on
pause(3)
view(150,30)

Maybe the following code is what you want:

[xSphere,ySphere,zSphere] = sphere(16);          %# Points on a sphere
hAX=scatter3(xSphere(:),ySphere(:),zSphere(:),'.');  %# Plot the points
hold on;      %# Add to the plot
xlabel('x');
ylabel('y');
zlabel('z');
axis off
plot([0 0],[-2 2],'r-.')
plot([-2 2],[0 0],'r-.')
plot3([0 0],[0 0],[-2 2],'r-.')
