<div class="PlainText">Hi Rafa,<br>

Here I present the task solved:<br>

//start of code<br>

nx=300;<br>

ny=200;<br>

X0=linspace(-1.2,1.2,nx);<br>

Y0=linspace(-1.5,2,ny);<br>

X=X0.*.ones(ny,1);<br>

Y=(Y0.*.ones(nx,1))';<br>

Z=(1.25*Y-sqrt(abs(X))).^2+X.^2-1;<br>

clf()<br>

a=gca();<br>

a.x_label.text="X";<br>

a.y_label.text="Y";<br>

contour(X0,Y0,Z',[0,0]);<br>

*Polyline=a.children.children(1)<br>

Polyline.fill_mode="on";<br>

Polyline.foreground=5;<br>

Polyline.background=5;<br>

Polyline.thickness=2;*<br>

a.view="2d";<br>

//end code<br>

<br>

Two questions:<br>

in the Helps of Scilab, where can I find the hierarchy trees for the graphic<br>

objects?<br>

How do I copy from SciNote to the Forum scripts and maintain the format of<br>

it?<br>

Thank you<br>

Hermes<br>
