I am currently trying to create a uiaxis object in app designer with no margins. Currently I have a 5 pixel margin around a uiaxis’s plot box (see the image below.). I have tried the following fixes;however , the 5 pixel margin persist:
  • Removed all labels, tics, grids,
  • Disabled box,
  • Set the xlim and ylim to [0,Inf]
  • Set the xlim and ylim to [-InF, Inf]
How do I remove the margin?
[1/16/2019] In other words, how do I make an axis's InnerPostion equal to its OuterPosition? Please note that my TighInset is already zero.
Most people would not care about 5 pixels, however the invisible margins create additional white space. I have positioned all of my components using the uigridlayout function. My layout makes sure that all components are separated by 10 pixels. The margins make the UIAXIS look as if it was accidently spaced 15 pixels from each component. This is unprofessional.
The Margin is the space between the blueline and the black box.
Here is the axis position information
K>> exampleAxis.OuterPosition
ans =
11 159 1000 400
K>> exampleAxis.InnerPosition
ans =
16 164 990 390
K>> app.DieAxes.TightInset
ans =
0 0 0 0
K>> exampleAxis.TightInset
ans =
0 0 0 0
Here all the properties. Please note that this is an example so there will be no reference to the gridlayout handle.

Hello,
You may find the answer checking the following post:
https://www.mathworks.com/matlabcentral/answers/360670-imshow-in-app-designer-image-size-doesn-t-fit
Where the code that at least worked for me was the following:
% Fill figure with axes and remove tick labels
app.UIAxes.Position = [0 0 app.UIFigure.Position(3:4)];
% Remove title, axis labels, and tick labels
title(app.UIAxes, []);
xlabel(app.UIAxes, []);
ylabel(app.UIAxes, []);
app.UIAxes.XAxis.TickLabels = {};
app.UIAxes.YAxis.TickLabels = {};
% Display image and stretch to fill axes
I = imshow('Flower.jpg', 'Parent', app.UIAxes, ...
'XData', [1 app.UIAxes.Position(3)], ...
'YData', [1 app.UIAxes.Position(4)]);
% Set limits of axes
app.UIAxes.XLim = [0 I.XData(2)];
app.UIAxes.YLim = [0 I.YData(2)];
You can also try to work with OuterPosition and InnerPosition properties.
Hope it works for you!
