axis_properties — description of the
axis entity properties
Description
The Axis entity is a leaf of the graphics entities hierarchy.
This entity defines the parameters for axis scaling and appearance.
| Axis properties | | visible: | This field contains the visible property value
for the entity . It should be "on" or "off" .
By default, the axis entity is visible, the value's property is
"on". If "off", the axis is not drawn on the screen. | | tics_direction: | Specify the direction of the tics drawn under the horizontal axis and
the vertical axis.
The possible values of this property are: | "top". In this case, tics are drawn at
the top of the horizontal axis.
| | "bottom". In this case, tics are drawn at
the bottom of the horizantal axis.
| | "left". In this case, tics are going left on
the vertical axis.
| | "right". In this case, tics are going right on
the vertical axis.
|
The defaults values are "top" for the horizontal axis and
"right" for vertical axis.
| | xtics_coord: | This field represent the x-coordinate of the axis. It is a row vector
containing values increasing from left to right which give tics positions
for a horizontal axis. Other case, the entity is a vertical axis, this
property contain a scale which defines the x-origin of the axis. | | ytics_coord: | This field represent the y-coordinate of the axis. It is a row vector
containing values increasing from bottom to top which give tics positions
for a vertical axis. Other case, the entity is a horizantal axis, this
property contain a scale which defines the y-origin of the axis. | | tics_color: | The value of this properties is index of the color used to draw the axis'lines and tics. | | sub_tics: | This field sets the number of tics to draw between two main
tics. | | tics_segement: | This field contains a flag which controls the display of the base segment of
the axis. The default is "on", else if to not display it, the property
takes "off" as value. | | tics_style: | This property describes how the tics are given. It is a string flag
which can have these possible values: | "v". It's the default value, In this case, tics positions
are given by the row factor xtics_coord for horizontal
axis (ytics_coord for the vertical one).
| | "r". In this case, tics positions are given by the
vector [min,max,n] where n is the number of intervals.
| | "i". In this case the vector given tics positions is of
size 4, [k1,k2,a,n] then values are increasing between
k1*10^a and k2*10^a , n is the number of intervals.
|
| | tics_labels: | This filed is a string matrix, which contains the strings to be drawn along
the axis at tics positions. | | labels_font_color: | This property determines the color of the tics labels. | | labels_font_size: | An integer specifying the font size used to draw the tics labels. | | clip_state: | This field contains the clip_state property
value for the arc. Clip_state value should be : | "off" this means that the axis is not clipped
| | "cliprf" this means that the
axis is clipped outside the Axes box.
| | "on" this means that the
axis is clipped outside the arc 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 axis to display, however clip_state property
value will be changed. | | parent: | This property contains the handle of the parent. The parent of the axis
entity should be of the type "Axes" or "Agregation". |
|
Examples
set("figure_style","new") //create a figure
a=get("current_axes");//get the handle of the newly created axes
a.data_bounds=[-1,-1,10,10];
drawaxis(x=2:7,y=4,dir='u');
a1=a.children(1)
a1.xtics_coord=[1 4 5 8 10];
a1.tics_color=2;
a1.labels_font_size=3;
a1.tics_direction="bottom";
a1.tics_labels= [" February" "May" "june" "August" "October"];
drawaxis(x=1.2:1:10,y=5,dir='u',textcolor=13);
a2=get("hdl")
a2.sub_tics=0;
a2.tics_segments="off";
a2.ytics_coord=4;
drawaxis(x=-1,y=0:1:7,dir='r',fontsize=10,textcolor=5,ticscolor=6,sub_int=10)
a3=get("hdl");
a3.tics_labels= 'B' +string(0:7);
a3.tics_direction="left";
