How do I fill the image completely into the chart in App Designer?

When I show the image on the chart, there are gaps in the right and bottom parts of the chart. How can I close these gaps?

A general solution would be -

axis('tight')

this code did not work

I will need more information to provide a working suggestion then.

Can you share the code you are working with?

Check that the XData and YData properties of the image object correspond to the XLim and YLim properties of the axes object. It looks like your axes are set to a fixed 300x250 and your image is smaller.

One possible solution for your plotted data without the white areas at the bottom and on the righthand side is exaplained via this simple demo example.

P =peaks();
figure(1)
imagesc(P)  % Good data is plotted

% Let's make some changes to the data P. 
% Add some data points intentionally:
P(end:end+10, :)=255; 
P(:,end:end+10) =255; 
figure(2)
imagesc(P)   % Yellowish area is added
% xlim([0, 60])
% ylim([0, 60])
axis tight

% Let's remove yellowish area: SOLUTION 
P_ok = P;
P_ok(end-10:end, :)=[];
P_ok(:,end-10:end, :)=[];
figure(3)
imagesc(P_ok)  % Back to the original data
