Create and control multiple axes
subplot divides the current figure into rectangular panes that are numbered row-wise. Each pane contains an axes. Subsequent plots are output to the current pane.
creates an axes in the
p-th pane of a figure divided into an
n matrix of rectangular panes. The new axes becomes the current axes.
p is a vector, it specifies an axes having a position that covers all the subplot positions listed in
If the specified axes already exists, delete it and creat a new axes.
makes the axes with handle
h current for subsequent plotting commands.
subplot('Position',[left bottom width height])
creates an axes at the position specified by a four-element vector.
height are in normalized coordinates in the range from 0.0 to 1.0.
h = subplot(...)
returns the handle to the new axes.
subplot specification causes a new axes to overlap any existing axes, then
subplot deletes the existing axes and uicontrol objects. However, if the
subplot specification exactly matches the position of an existing axes, then the matching axes is not deleted and it becomes the current axes.
clf deletes all axes objects and returns to the default
You can omit the parentheses and specify subplot as.
m refers to the row,
n refers to the column, and
p specifies the pane.
Special Case - subplot(111)
subplot(111) is not identical in behavior to
subplot(1,1,1) and exists only for compatibility with previous releases. This syntax does not immediately create an axes, but instead sets up the figure so that the next graphics command executes a
reset (deleting all figure children) and creates a new axes in the default position. This syntax does not return a handle, so it is an error to specify a return argument. (This behavior is implemented by setting the figure's
NextPlot property to
income in the top half of a figure and
outgo in the bottom half,
The following illustration shows four subplot regions and indicates the command used to create each.
