MATLAB: A trouble with saving an image generated by bar3()

bar3figure saving on diskmetafile saving on disk

I have used bar3() to draw a graph, but when I use the pseudo code below, an aliased low resolution image is saved on disk. I tried to save using File>Save but the result was the same:

figure(2) bar3(class_n,FRR); print('-f2','-dmeta','FRR Criterion')

What should I do to save as a vector or high resolution image?

MATLAB: Saving large files using uisave

use uiputfile instead. Credit to Jan.

[filename, filepath] = uiputfile('*.mat', 'Save the project file:');
FileName = fullfile(filepath, filename);
save(FileName, 'yourVariable', '-v7.3');

It is necessary to reverse the order:

%%%%%%%%%%Bin1
   data1 = data(Bin6_BeginRow:Bin6_EndRow, :);
   data2 = zeros(max(data1(:, 1)), max(data1(:, 5)));
   for i = 1:length(data1)

       if zz > data2(xx, yy)
           data2(xx, yy) = zz;
       end
   end
   bar3(data2)
   b = bar3(data2);

This should do what you want.
