MATLAB Version: 8.2.0.701 (R2013b)

I create a figure with 4 subplots. When I save the figure using the Figure Menu: File-Save, everything looks fine. If I use the saveas or the print functions, the Y axes change and the representation of the data is incorrect.

Menu Save (Correct):

saveas or print (Incorrect):

      %%Save the Figure
      jpg_path = '\\usdrdsech1na002\projects$\PUBLIC\PureWaveLinear\Build Info\AcousticMicroscope\TOF_Scans';
          set(hc,'PaperOrientation','portrait');
      tmp = strfind(tmpname,' ');
      tmpname(tmp) = '_'; clear tmp
      saveas(hc, fullfile(jpg_path, [tmpname '.jpg']));
      %print(hc, '-djpeg', fullfile(jpg_path, [tmpname '.jpg']));

I have the same issue, but the solution above doesn't fix it.

set(gcf, 'InvertHardcopy', 'off');
saveas(gcf, plotfile);

I've tried "exportgraphics" and some of the other solutions but I still get the wrong scale lables on the X axis on all plots on the right side of my tiled plots. Top is the Figure in MATLAB, bottom is the .png. One of the changes I tried:

set(gca,'XTick',Expected(s+1:e,2));

added an extra data point at the end causing 1 to 100 to compress. The plot and the .png matched! But it was still wrong...

>> Expected(s+1:e,2)

ans =

0.0010

0.0100

0.1000

1.0000

9.9999

24.6680

99.9990

update:

f=figure('Position', [500, 200, 1050, 750],'Color','white');
plotdata=tiledlayout(3,2,'TileSpacing','tight', 'Padding','tight'); %hold on;

TileSpacing influence the outcome. With 'loose' we lose resolution on the axis ticks.

Changed figure code (larger scale) and it works:

f=figure('Position', [500, 200, 1120, 800],'Color','white');

The following code resolves the figure resizing issue:

>> set(fig, 'PaperPositionMode', 'auto');

where 'fig' is your figure handle. You can also just pass 'gcf'.

The 'PaperPositionMode' property (as published in documentation) "ensures that the printed version is the same size as the onscreen version. With 'PaperPositionMode' set to 'auto' MATLAB does not resize the figure to fit the current value of the 'PaperPosition'."

Refer to the various properties listed in the figure properties and axes properties documentation for additional saving and printing settings that may affect the look of your figure when exporting to printer or file.

Thanks for the help. That fixed the problem. I still find it odd, that with the figure/jpg size aside, why the scales on the individual plots changed but the plotted data did not.
