在Matlab /八度中绘制没有轴和键合盒的图形

Question

I have two plots below. How can I get rid of the axis and the bonding box on the second plot? I'm using octave 3.8.1

Plot command I use to create plots.

clf(figure(1))
figure (1);
plot(xfreq_orig(1:3000),yamp_orig(1:3000)); 
print ('-dpng','-S1024,768', strcat('/tmp/','01_graph.png')); %export plot to file

hold on;

clf(figure(2))
figure (2);
plot(xfreq_orig(1:3000),yamp_inv(1:3000),'r')
print ('-dpng','-S1024,768', strcat('/tmp/','02_graph.png')); %export plot

Answer 1

It's as simple as

axis off

You could also try

box off

which just disable some parts of the axis border
