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 `Xgrayplot` , `Matplot` and `Matplot1` ).

  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 matrix (n1,n2) which constitue the coordinates of a 2D plots of surface.
  data_mapping: By default the value of this property `"scaled"` , the indices of painting colors are proportional to the value `z` coordinates. In another case the property take as value `"direct"` where the plot is a grayplot and the indices of painting colors are given by the data.
  parent: This property contains the handle of the parent. The parent of the grayplot (Matplot) entity should be of the type `"Axes"` .

### Examples

       set("figure_style","new") //create a figure

       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 ploting of a matrix using colors
       xbasc()
       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
