problem with errorbars and export_fig

Asked by Rhys
on 16 Jun 2013

Hi everybody, I have come across a strange problem while using export_fig(). It does not seem to export errorbars

x=1:10;
y=x.^2-2*rand(size(x));
err=abs(x.^2-y);
errorbar(x,y,err,'r*')
legend('data'
export_fig(gca,'testing.jpg')
hold on
plot(x,y,'--')
export_fig(gca,'testing2.jpg')

When I try to run this code (or anything with errorbars) export_fig() leaves the errorbars out. In the example code testing.jpg appears to me as a blank set of axis. I noticed that if I use plot() to plot the markers onto the axes export_fig works just fine. Is there something extra I need to add into export _fig to make it work with errorbars?

Cheers

Rhys

Export_fig exports error bars just fine. Try:

x=1:10;
y=x.^2-2*rand(size(x));
err=abs(x.^2-y);
errorbar(x,y,err,'r*')
export_fig(gcf,'testing.jpg')
hold on
plot(x,y,'--')
export_fig(gcf,'testing2.jpg')

Rhys, notice the tiny but critical difference in the code. Oliver is exporting the current figure (gcf) where you were trying to export the current axes (gca).

Thank you Oliver and cyclist. export_fig() is now doing exactly what I want with it! Thanks for your help! It will undoubtedly will be a great tool as a pursuit physics!

Cheers,

Rhys!

Try adding a drawnow command before the first export_fig. Does it work?

It does not change.
