grayplot properties
description of the grayplot entities properties
Description
The Grayplot entity is a leaf of the graphics entities hierarchy. It
represents 2D plots of surface using colors and images (see
grayplot
, Sgrayplot
, fgrayplot
and
Sfgrayplot
).
- parent:
This property contains the handle of the parent. The parent of the grayplot entity should be of the type
"Axes"
.- children:
This property contains a vector with the
children
of the handle. However,grayplot
handles currently do not have anychildren
.- 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 field defines a
tlist
data structure of type"grayplotdata"
composed of a row and column indices of each element : the x and y grid coordinates are contained respectively indata.x
anddata.y
. The complementary field nameddata.z
is the value of the surface at the point(x(i),y(j))
(scaled mode) or the centered value of the surface defined between two consecutivex(i)
andy(j)
(direct mode). Ifdata_mapping
(see below) is set to"scaled"
, the entire z data is used to perform a color interpolation whereas, ifdata_mapping
's value is"direct"
, the last line and column of the z data indices are ignored and the color is determined directly in the colormap by the indices of the submatrixdata.z(1:$-1,1:$-1)
.- data_mapping:
By default the value of this property is
"scaled"
: the indices of painting colors are proportional to the valuez
coordinates. In the other case, the property takes as value"direct"
where the plot is a grayplot and the indices of painting colors are given by the data (see above).- clip_state:
This field contains the
clip_state
property value for the grayplot. It should be :"off"
this means that the grayplot is not clipped."clipgrf"
this means that the grayplot is clipped outside the Axes box."on"
this means that the grayplot is clipped outside the rectangle given by property clip_box.
- clip_box:
This field is to determinate the
clip_box
property. By Default its value should be an empty matrix if clip_state is "off". Other cases the vector[x,y,w,h]
(upper-left point width height) defines the portions of the grayplot to display, howeverclip_state
property value will be changed.- user_data:
This field can be use to store any scilab variable in the grayplot data structure, and to retreive it.
Examples
m=5;n=5; M=round(32*rand(m,n)); grayplot(1:m,1:n,M) a=get("current_axes"); a.data_bounds= [-1,-1;7,7] h=a.children h.data_mapping="direct"; // A 2D plotting of a matrix using colors clf() a=get("current_axes"); a.data_bounds= [0,0;4,4]; b=5*ones(11,11); b(2:10,2:10)=4; b(5:7,5:7)=2; Matplot1(b,[1,1,3,3]) ; h=a.children for i=1:7 xclick(); // click the mouse to sets Matplot data h.data=h.data+4; end
