[Scilab-users] A question about plotting

[Floyd Xu]

Hi , All:

I have a question about plotting.

I want to plot 2 lines in a graphic , so I type the command as below:

-->x=linspace(0,2*%pi,40);
-->y1=sin(x)

-->y2=cos(x);
-->X=[x,x];
-->Y=[y1,y2];

Then , I type the plot command :

-->plot(x,y1,x,y2);

The result is shown as below:

[Graphic window number 0 (2).bmp]

But when I type a command as below:

-->plot(X,Y);

The result is :
[Graphic window number 0.bmp]

It  has an additional line.

Why will this line appear?

Thanks for your reply.
