16.5 Plot Annotations

— Function File: title (title)

Create a title object and return a handle to it.

— Function File: legend (st1, st2, ...)
— Function File: legend (st1, st2, ..., pos)
— Function File: legend (matstr)
— Function File: legend (matstr, pos)
— Function File: legend (cell)
— Function File: legend (cell, pos)
— Function File: legend ('func')

Legend puts a legend on the current plot using the specified strings as labels. Use independant strings (st1, st2, ...), a matrix of strings (matstr), or a cell array of strings (cell) to specify legends. Legend works on line graphs, bar graphs, etc. Be sure to call plot before calling legend.

pos optionally places the legend in the specified location:

-1 To the top right of the plot
0 Don't move the legend box (default)
1 Upper right-hand corner
2 Upper left-hand corner
3 Lower left-hand corner
4 Lower right-hand corner

Some specific functions are directely avaliable using func:

show
Show legends from the plot
hide
off
Hide legends from the plot
boxon
Draw a box around legends
boxoff
Withdraw the box around legends
left
Text is to the left of the keys
right
Text is to the right of the keys

— Function File: h = text (x, y, label)
— Function File: h = text (x, y, z, label)

Create a text object with text label at position x, y, z on the current axes. The label may be followed by property-value pairs.

— Function File: xlabel (string)
— Function File: ylabel (string)
— Function File: zlabel (string)

Specify x, y, and z axis labels for the plot.

— Function File: box (arg)
— Function File: grid (h, ...)

Control the display of a border around the plot. The argument may be either "on" or "off". If it is omitted, the current box state is toggled.

     
     
See also: grid.

— Function File: grid (arg)
— Function File: grid ("minor", arg2)

Force the display of a grid on the plot. The argument may be either "on" or "off". If it is omitted, the current grid state is toggled.

If arg is "minor" then the minor grid is toggled. When using a minor grid a second argument arg2 is allowed, which can be either "on" or "off" to explicitly set the state of the minor grid.
