From: Jeff on 20 Mar 2010 00:27 How can I fix the axes so they don't change? I keep setting it, and then every time I add something, it resets. I can't find the answer in the doc set or online. cells=zeros(dim); cells(seed(1),seed(2))=64; image(cells); axis equal; axis tight; walkers=zeros(num,2); walkers(:,1)=randi(dim(1),num,1); walkers(:,2)=randi(dim(2),num,1); for ii=1:num cells(walkers(ii,1),walkers(ii,2))=40; end image(cells); axis equal; axis tight; See how I have to set the axis every time? Thanks,

Change the XLimMode, YLimMode, and/or ZLimMode properties of your axes. http://www.mathworks.com/access/helpdesk/help/techdoc/ref/axes_props.html#XLimMode -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ

Oops, I spoke too soon. Sorry about that. Setting the LimModes is not stopping the axes from being resized when I issue a new image command. The LimModes only have prevent the axes from being changed if you turn 'hold on'. But I can't do that, since it uses way too much memory and slows down my program to a crawl. Here's the basics of my program (I'm trying to imitate diffusion limited aggregation): seed=[randi(dim(1)) randi(dim(2))]; cells=zeros(dim); cells(seed(1),seed(2))=stable; image(cells); % Causes the axes to be resized according to the size of 'cells'. axis equal; axis tight; axis off; axis manual; drawnow; -create matrix of 'walker' particles, same size as 'cells' while stable~=0 -randomly move 'walkers' around their matrix image(cells+walkers); % This line resizes and reshows the axes again, even though 'axis ma end I need this for my homework and it's killing me. OTOH, I'm probably getting an A in this class anyway. Thanks for any help, |
