Scilab Data type fec_properties - description of the
fec entities properties
Description
The Fec entity is a leaf of the graphics entities hierarchy. It
represents 2D finite elements plots (see
fec, Sgrayplot).
visible:
This field contains the visible property value
for the entity . It should
be "on" or "off" . By default,
the plot is visible, the value's property is "on"
. If "off" the plot is not drawn on the screen.
data:
This is a three column matrix [x,y,f], where x(i)
and y(i) are the coordinates of the i'th
node. f(i) is the value associated to the node i.
triangles:
This is a five column matrix
[tn,n1,n2,n3,flag]. tn(j) is the
triangle number. n1(j), n2(j) and
n3(j) are the index of the nodes which constitute
the triangle.
(flag(j) is not used).
parent:
This property contains the handle of the parent. The parent of the fec
entity should be of the type "Axes" or "Agregation".
Examples
set("figure_style","new"); //create a figure
x=-10:10; y=-10:10;m =rand(21,21);
Sgrayplot(x,y,m);
a=get("current_axes");
f=a.children.children(2)
f.data(:,3)=(1:size(f.data,1))';
a.parent.color_map=hotcolormap(64);
