Re: Mismatch between plotted graph and its saved file.

[Kavya Manohar]

Hi,

My OS is Ubuntu 13.10 and Octave is version 3.6.4

When I run this code, I get a figure window which plots sinusoid, but not the straight line.(Its screenshot is here: testfig.png)

When that figure window is maximized, I get the straight line too.!!(Its screenshot is here: testfig2.png)

But the saved figure contains no straight line. (test.png, the file saved by octave)

And the problem persists only with horizontal straight lines.

Thanks

Kavya

Hi,

I plotted a sinusoid and a straight horizontal line on same graph. But when it was saved  in '.png' format using print function the straight line did not appear in the figure. 

The following is the code.

f=50;

t=[0:1/(35*f):3/f];

Vm=12*sqrt(2);

A=Vm*sin(2*pi*f*t);

plot(t,A,"1",t,Vm,"1");

print("test.png")

Why could it be so? What is the way out?

Thanks
