Hi Rafa,
Here I present the task solved:
//start of code
nx=300;
ny=200;
X0=linspace(-1.2,1.2,nx);
Y0=linspace(-1.5,2,ny);
X=X0.*.ones(ny,1);
Y=(Y0.*.ones(nx,1))';
Z=(1.25*Y-sqrt(abs(X))).^2+X.^2-1;
clf()
a=gca();
a.x_label.text="X";
a.y_label.text="Y";
contour(X0,Y0,Z',[0,0]);
*Polyline=a.children.children(1)
Polyline.fill_mode="on";
Polyline.foreground=5;
Polyline.background=5;
Polyline.thickness=2;*
a.view="2d";
//end code

Two questions:
in the Helps of Scilab, where can I find the hierarchy trees for the graphic
objects?
How do I copy from SciNote to the Forum scripts and maintain the format of
it?
Thank you
Hermes
