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(1)
f.data(:,3)=(1:size(f.data,1))';
a.parent.color_map=hotcolormap(64);
