<hold> - Hold current graph.

HOLD Hold current graph

HOLD ON holds the current plot and all axis properties so that

subsequent graphing commands add to the existing graph.

HOLD OFF returns to the default mode whereby PLOT commands erase

the previous plots and reset all axis properties before drawing

new plots.

HOLD, by itself, toggles the hold state.

HOLD does not affect axis autoranging properties.

HOLD ALL holds the plot and the current color and linestyle so

that subsequent plotting commands will not reset the color and

linestyle.

HOLD(AX,...) applies the command to the Axes object AX.

Algorithm note:

HOLD ON sets the NextPlot property of the current figure and

axes to "add".

HOLD OFF sets the NextPlot property of the current axes to

"replace".

<axes> - Create axes in arbitrary positions.

AXES Create axes in arbitrary positions.

AXES('position', RECT) opens up an axis at the specified location

and returns a handle to it.

RECT = [left, bottom, width, height] specifies the location and

size of the side of the axis box, relative to the lower-left

corner of the Figure window, in normalized units where (0,0)

is the lower-left corner and (1.0,1.0) is the upper-right.

AXES, by itself, creates the default full-window axis and returns

a handle to it.

AXES(H) makes the axis with handle H current.

Execute GET(H) to see a list of axes object properties and

their current values. Execute SET(H) to see a list of axes

object properties and legal property values.

<subplot> - Create axes in tiled positions.

SUBPLOT Create axes in tiled positions.

H = SUBPLOT(m,n,p), or SUBPLOT(mnp), breaks the Figure window

into an m-by-n matrix of small axes, selects the p-th axes for

the current plot, and returns the axes handle. The axes are

counted along the top row of the Figure window, then the second

row, etc. For example,

SUBPLOT(2,1,1), PLOT(income)

SUBPLOT(2,1,2), PLOT(outgo)

plots income on the top half of the window and outgo on the

bottom half. If the CurrentAxes is nested in a uipanel the

panel is used as the parent for the subplot instead of the

current figure.

SUBPLOT(m,n,p), if the axes already exists, makes it current.

SUBPLOT(m,n,p,'replace'), if the axes already exists, deletes it and

creates a new axes.

SUBPLOT(m,n,p,'align') places the axes so that the plot boxes

are aligned, but does not prevent the labels and ticks from

overlapping.

SUBPLOT(m,n,P), where P is a vector, specifies an axes position

that covers all the subplot positions listed in P.

SUBPLOT(H), where H is an axes handle, is another way of making

an axes current for subsequent plotting commands.

SUBPLOT('position',[left bottom width height]) creates an

axes at the specified position in normalized coordinates (in

in the range from 0.0 to 1.0).

SUBPLOT(..., PROP1, VALUE1, PROP2, VALUE2, ...) sets the

specified property-value pairs on the subplot axes. To add the

subplot to a specific figure pass the figure handle as the

value for the 'Parent' property.

If a SUBPLOT specification causes a new axes to overlap an

existing axes, the existing axes is deleted - unless the position

of the new and existing axes are identical. For example,

the statement SUBPLOT(1,2,1) deletes all existing axes overlapping

the left side of the Figure window and creates a new axes on that

side - unless there is an axes there with a position that exactly

matches the position of the new axes (and 'replace' was not specified),

in which case all other overlapping axes will be deleted and the

matching axes will become the current axes.

SUBPLOT(111) is an exception to the rules above, and is not

identical in behavior to SUBPLOT(1,1,1). For reasons of backwards

compatibility, it is a special case of subplot which does not

immediately create an axes, but instead sets up the figure so that

the next graphics command executes CLF RESET in the figure

(deleting all children of the figure), 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. The delayed CLF RESET

is accomplished by setting the figure's NextPlot to 'replace'.

Be aware when creating subplots from scripts that the Position

property of subplots is not finalized until either a drawnow

command is issued, or MATLAB returns to await a user command.

That is, the value obtained for subplot i by the command

get(h(i),'Position') will not be correct until the script

refreshes the plot or exits.

Viewpoint control

<view> - 3-D graph viewpoint specification.

VIEW 3-D graph viewpoint specification.

VIEW(AZ,EL) and VIEW([AZ,EL]) set the angle of the view from which an

observer sees the current 3-D plot. AZ is the azimuth or horizontal

rotation and EL is the vertical elevation (both in degrees). Azimuth

revolves about the z-axis, with positive values indicating counter-

clockwise rotation of the viewpoint. Positive values of elevation

correspond to moving above the object; negative values move below.

VIEW([X Y Z]) sets the view angle in Cartesian coordinates. The

magnitude of vector X,Y,Z is ignored.

Here are some examples:

AZ = -37.5, EL = 30 is the default 3-D view.

AZ = 0, EL = 90 is directly overhead and the default 2-D view.

AZ = EL = 0 looks directly up the first column of the matrix.

AZ = 180 is behind the matrix.

VIEW(2) sets the default 2-D view, AZ = 0, EL = 90.

VIEW(3) sets the default 3-D view, AZ = -37.5, EL = 30.

[AZ,EL] = VIEW returns the current azimuth and elevation.

T = VIEW returns the current general 4-by-4 transformation matrix.

VIEW(AX,...) uses axes AX instead of the current axes.

<viewmtx> - View transformation matrix.

VIEWMTX View transformation matrix.

A=VIEWMTX(AZ,EL) returns the 4x4 orthographic transformation

matrix, A, used to project 3-D vectors onto the 2-D plot surface.

Uses the same definition for azimuth and elevation as VIEW, in

particular, AZ and EL must be in degrees. Returns the same

transformation matrix as the commands

VIEW(AZ,EL)

A = VIEW

but doesn't change the current VIEW.

A=VIEWMTX(AZ,EL,PHI) returns a 4x4 perspective transformation

matrix used to project 3-D vectors onto the 2-D plot surface.

PHI is the subtended view angle of the normalized plot cube

(in degrees) and controls the amount of perspective distortion:

PHI = 0 degrees is orthographic projection

PHI = 10 degrees is like a telephoto lens

PHI = 25 degrees is like a normal lens

PHI = 60 degrees is like a wide angle lens

A=VIEWMTX(AZ,EL,PHI,XC) returns the perspective transformation

matrix using XC as the target (or look-at) point within

the normalized plot cube. XC=[xc,yc,zc] specifies the

point (xc,yc,zc) in the plot cube. The default value is

the closest point in the plot cube,

XC = 0.5+sqrt(3)/2*[cos(EL)*sin(AZ),-cos(EL)*cos(AZ),sin(EL)].
