Saving a 1xn Bar plot as a jpg

Hello,

y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];

test = bar(y)

I want to save this bar plot as an image programatically. I have no issues saving a 1x1 Bar using saveas(), but when I have a 1xN Bar then I get this errorr:

Error using checkArgsForHandleToPrint

Can print only one page at a time.

Error in checkArgsForHandleToPrint

Error in print>LocalCreatePrintJob (line 101)

handles = checkArgsForHandleToPrint(0, varargin{:});

Error in print (line 38)

[pj, inputargs] = LocalCreatePrintJob(varargin{:});

Error in saveas (line 181)

print( h, name, ['-d' dev{i}] )

How can I programatically save a 1xN bar plot?

saveas() is quite an old function and not suitable for getting high-quality images. If you are using a recent version of MATLAB, then try exportgraphics()

y = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
bar(y)
exportgraphics(gcf, 'filename.jpg', 'Resolution', 300)

If you are using an older version which does not have exportgraphice() then use this FEX package: https://www.mathworks.com/matlabcentral/fileexchange/23629-export_fig
