how to set position and outerposition respectively the same as from another axes?

19 views (last 30 days)
I want to display a scalebar on a 3d plot. When I rotate the 3d plot, I want to keep the scalebar still. The way I approach it is to create another axes, copying the same xlim, ylim, zlim, etc properties, plot a line as the scalebar, and lastly axis off;
I however encounter a strange problem. It seems not able to set position and outerposition simultaneously the same, which should be doable but I didn't get it yet.
Please help. below is my scalebar function. input h is from h=subplot(231) for example.
function scalebar(h)
obj=findobj('tag','scalebar');
if ~isempty(obj),delete(obj);end
haxes=axes;set(haxes,'tag','scalebar');
ylim=get(h,'ylim');set(haxes,'ylim',ylim);
xlim=get(h,'xlim');set(haxes,'xlim',xlim);
zlim=get(h,'zlim');set(haxes,'zlim',zlim);
ytick=get(h,'ytick');set(haxes,'ytick',ytick);
xtick=get(h,'xtick');set(haxes,'xtick',xtick);
ztick=get(h,'ztick');set(haxes,'ztick',ztick);
DataAspectRatio=get(h,'DataAspectRatio');set(haxes,'DataAspectRatio',DataAspectRatio);
bar_um=10;
line([-0.5 0.5]*bar_um,[0 0],'color','k');
text(-0.3*bar_um,-0.2*bar_um,[ num2str(bar_um) '\mum'],'fontsize',18);
% axis off
axis on;axis vis3d;grid on;view(0,0); % for debug
pos=get(h,'position');
pos(1)=pos(1)+0.05;
pos(2)=pos(2)-0.1;
set(haxes,'position',pos);
axes(h);
clc % below for debug
get(h,'position')
get(haxes,'position')
get(h,'outerposition')
get(haxes,'outerposition')
end

No, you cannot set the 'position' and the 'outerposition' to the same value.
Type this in the command window to find the corresponing documentation:
docsearch outerposition

Hi Jan, sorry that I should clarify my question. I want to create an axes whose position and outerposition respectively same to that of an existing axes. I have verified that it is manually doable but can't get it done by
pos=get(h,'position');
set(haxes,'position',pos);
opos=get(h,'outerposition');
set(haxes,'outerposition',opos);
