Why does the box outline not appear on top of figure?

The code below gives me a figure with no box outline on top (see attached file). I have tried many things, including "box on" and Clipping off but have not managed to find out how to add the top line (even artificially, if necessary). I'm thankful for any advice!

x=linspace(0,1,201);
y=linspace(0,1,201);

for n = 999

a=zeros(201,4020);      %this is a matrix of size 201 times 4020
  
cellsICC=a(:,202:402);

colorbarOn=1; %1 if want them; 0 if not

[I1,J1] = find(vessels1>0); 

figure
pcolor(x,y,cellsICC)
colormap(flipud(bone));
set(gca,'XTick',[])
set(gca,'YTick',[])
set(gca, 'Box', 'on');
set(gcf,'color','w');
axis square
        if colorbarOn==1
           cbh=colorbar ('eastoutside');
           set(cbh,'YTick',0:1:max(max(max(cellsICC)),2));
        end
view([0 90])
caxis([0 max(max(max(cellsICC)),2)])
shading flat

for i=1:length(I1)
line(x(J1(i)),y(I1(i)),'Color','Red','LineWidth',0.1,'Marker','.')
end

end

Hi Linnea Franssen,

your code example cannot be executed. Nevertheless, did you try to add:

 set(gca,'Box','on');

Kind regards,

Robert

Sorry about that. I will replace the matrix by zeros to make it executable as it still gives the result that looks like it is cut off on top.

I did try adding what you suggested. I will add it to the example so you can see where I put it. It did not work unfortunately.

Thanks for much for your help!

Hi Linnea Frannsen,

I tried to change the renderer but the axes kept disappeared. I found this thread:

https://de.mathworks.com/matlabcentral/answers/25028-bug-in-pcolor

But Jan's workaround did not work for me.

imagesc() works well:

 fh = figure;
 ah = axes('Parent',fh);
 imagesc(ah,x,y,cellsICC)
 colormap(fh,flipud(bone));
 set(ah,'XTick',[])
 set(ah,'YTick',[])
 set(ah, 'Box', 'on');
 set(fh,'color','w');
 axis square
        if colorbarOn==1
           cbh=colorbar ('eastoutside');
           set(cbh,'YTick',0:1:max(max(max(cellsICC)),2));
        end
 view([0 90])
 caxis(ah,[0 max(max(max(cellsICC)),2)])
 shading flat

Kind regards,

Robert
