Graphics Programs Reference
In-Depth Information
There are usually a great many properties associated with a given
graphical object. For example the
x
- and
y
-axis limits are given by two
separate properties,
xlim
and
ylim
. Continuing with the example above:
>> get(gca,'xlim')
ans =
0 10
>> get(gca,'ylim')
ans =
-1
1
The locations of the
x
-axis tick marks are another property:
>> get(gca,'xtick')
ans =
0
2
4
6
8
10
The width of the line used to draw the axes is
>> get(gca,'linewidth')
ans =
0.5
(Your line width might be different.) There are many more. To get
a complete list of the properties of a graphical object, leave out the
property argument in a call to
get
. For example, the properties of the
Axes object are
>> get(gca)
AmbientLightColor = [1 1 1]
Box = on
CameraPosition = [3.5 0 17.3205]
CameraPositionMode = auto
CameraTarget = [3.5 0 0]
CameraTargetMode = auto
CameraUpVector = [0 1 0]
(and so on)
And the properties of a Line object are (carrying on from the sine-wave
example above):
>> get(h)
Color = [1 0 0]
EraseMode = normal
LineStyle = -
LineWidth = [0.1]
Marker = o
MarkerSize = [6]
