Hello guys, how are you?
I got a piece of my code which meant to show and export a histogeram automatutically. it works somewhy for the first indice, but then it fails. i saw several posts about this problem, which talked about handle (which I don't use anyways) and critical failure of indexing (which I belive it is not in my case).
the code:
for n=1:length(allcellsnames)
subplot(1,3,n)
histogram(allcellsareastot{1,n});
myAxes=findobj(finalhis,'Type','Axes');
fnfh=append(append(erase(lastentryname, '.csv'),' finalhis'));
fhpath=(append(pwd ,append('\',append('summary figure', append('\',append('summary figure ', append(num2str(minint(n)), append(' i ', append(num2str(maxint(n)), '.png')))))))))
exportgraphics(myAxes,(fhpath));
analysisdata{9+n,1}=allcellsnames{n};
analysisdata{9+n,2}=allcellsareastot{1,n};
end
The first indice goes good and it saves my image. in the second it subplots it to the figure, but somewhy fails to save.
it fails in the " exportgraphics(myAxes,(fhpath));"
here is the output that shows the first is fine, but the second messed up:
fhpath =
'C:\Users\Ifrac\Desktop\מעבדה\matlab\Voronoi analysis\voronoi code test\summary figure\summary figure 0.5 i 40.png'
fhpath =
'C:\Users\Ifrac\Desktop\מעבדה\matlab\Voronoi analysis\voronoi code test\summary figure\summary figure 1 i 45.png'
Error using exportgraphics
Dot indexing is not supported for variables of this type.
Error in Voronoi_exclude_borders_21122022allclareamatrixndfx (line 378)
exportgraphics(myAxes,(fhpath));
I would really appriciate any help :)
Thanks,
Amit.

What is FINALHIS ?
Note that you do not need to call APPEND() multple times in one line like that: APPEND() accepts multiple inputs, so you only need to call it once. Even better would be to replace it with FULLFILE() and SPRINTF().

As you stated: finalhis=figure(ADcntr);
Then this command: exportgraphics(myAxes,(fhpath));
has to be:
exportgraphics(finlhis,fhpath);

Welcome. It requires a figure handle and thus, you'd need such syntax.

exportgraphics(OBJ, FILESPEC) saves the specified graphics to a file.
OBJ is the handle of any type of an axes, a figure, a chart that can
be a child of the figure, a tiled chart layout, or a container within
the figure.

try
myAxes = subplot(1,3,n);
histogram(myAxes, allcellsareastot{1,n});
with no find()

I do not know where you got the idea that allcellsareastot was to be passed to exportgraphics.
for n=1:length(allcellsnames)
myAxes = subplot(1,3,n);
histogram(myAxes, allcellsareastot{1,n});
fnfh=append(append(erase(lastentryname, '.csv'),' finalhis'));
fhpath=(append(pwd ,append('\',append('summary figure', append('\',append('summary figure ', append(num2str(minint(n)), append(' i ', append(num2str(maxint(n)), '.png')))))))))
exportgraphics(myAxes,(fhpath));
analysisdata{9+n,1}=allcellsnames{n};
analysisdata{9+n,2}=allcellsareastot{1,n};
end

By the way, we recommend that you use fullfile() instead of building file names with '/' or '\' yourself.
