When interchanging the units of graphics objects in MATLAB, the way the figure appears in one environment may be drastically different in another. This can be caused by a difference in monitors and screen resolutions especially if the 'pixel' unit is being used. A best practice is to stay consistent with using the 'normalized' unit for these objects which gets rendered in respect to its parents opposed to the screen. If you have code that looks the way you want but is using a variety of units, try using the following function to find all instances of units to 'normalized' within your figure:
function [] = normalize(obj)
%sets to normal if it can
prop = properties(obj);
if(sum(ismember(prop,'Units')))
obj.Units = 'normalized';
end
%recurses on all the children
if(~isempty(obj.Children))
for i = 1:length(obj.Children)
normalize(obj.Children(i));
end
end
end
