Axis tick labels changed upon export to EPS

Hi all,

Duplicate post from the discussion forum here:

http://groups.google.com/group/comp.soft-sys.matlab/browse_thread/thread/9ab0c6353416aa0f

because I think it's a reasonable question!

I am using Matlab R2010b.

I have manually changed the axis tick labels for some of my plots and am experiencing some weird behaviour.

I have saved the figures (.fig) and the axis tick marks are correct. I can export to PNG or PDF with no problems. When I export to EPS however the axis tick marks have been altered and are completely incorrect.

Fig file is here if you want to play with it:

Any ideas? Surely a bug if it is specific to EPS export?!

Thanks for any suggestions,

Gabriel

The figure exports fine to EPS on my machine. Do you have Ghostscript and Ghostview installed?

Answer 1

Fixed:

The problem with specifying your own axis tick labels is that the property (for the y-axis here) YTickLabelMode is set to manual but the property YTickMode remains at auto.

When exporting to EPS, for some very odd reason the figure must be slightly rescaled (which is not the case/the rescaling is different when choosing PDF or PNG). The tick positions are automatically reassigned, but the labels remain those specified manually. Result: unexpected and rubbish figures!

Setting the axis property YTickMode to manual fixes this.

Of course this is only a problem if the rescaling step causes the tick positions to change, so Oliver Woodford probably didn't observe this.

I still think this is buggy behaviour - why should one type of export cause figure resizing when another doesn't?

Thanks for your suggestions everybody!

thanks a lot... solved my problem! /john

The same when exporting to JPG

[Steven]

For me also this problem arises when exporting to PDF!

But I have not been able to resolve it by changing tickmode to manual.

Any other solution?

Is this a bug?

Thanks!

@Steven: Please open a new thread and post the relevant code there. I assume the mistake is concealed in "changing the tickmode to manual". How did you do this exactly?

[Steven]

Hi.

Thanks.

Already did. Here it is

This bug is still relevant ten years later. Thank you so much, @Gabriel Rosser, for sharing such a simple and elegant solution!

I think the problem is solved when you set ylim manually.

[Matt Fig]

I only use this for exporting figures.

Export_fig

[Gabriel Rosser]

Nice function, thanks for pointing it out. Unfortunately it has exactly the same problem though - axis markings are messed up after exporting.

[Matt Fig]

I will notify the author, thanks.

[Oliver Woodford]

export_fig worked fine for me in R2010b on Windows 7 64-bit. The axis markings were as in the figure.

[Gabriel Rosser]

Oh sorry Oliver I just realised you mean you tried export_fig with my actual figure? That's very strange. Only difference I can think is I'm running Linux 64bit. Anyway, thanks very much for trying it and see my answer below for the fix.

[Oliver Woodford]

Yes, I was using your figure. Anyway, glad you found a solution. If I can replicate the bug I may put a fix into export_fig.
