HelpFile
|
Normally when you click on the the 'Help' tag in
the menu box, plt
will display the file
plt.chm on Windows systems and the file
plt.htm otherwise.
For compiled applications, plt will look for these files in the folder
containing the .exe file and for .m applications plt will search the MatLab path
for these files. A different help file may be specified by using the 'HelpFile'
parameter:
|
'HelpFile','filename' |
If the filename is specified without any path, plt uses
looks for this file in the folder containing the currently running
.m file (or in the same folder
containing the .exe file for compiled applications). The file extension
must be included in the filename string. If the extension is
.chm then the help file viewer is opened (allowed
on Windows systems only) and for all other file types, the default
browser of the OS is used to open the specified file. |
|
'HelpFile', 'drive:\path\filename' |
As above, plt opens the specified file using the help
file viewer or the default browser. When path information is supplied, plt will look for the file
only in the location given. As before the file extension
must be included in the filename string. |

Options
|
plt(...,'Options',s);
s is a string specifying one or more options. The options allowed
are:
| |
'Ticks' |
Use tick marks (i.e. no grid lines) |
| |
'Menu' |
Enable the figure menu bar |
| |
'Slider' |
Enable the x-axis control slider |
| |
'Xlog' |
use logarithmic
scaling on the x axis |
| |
'Ylog' |
use logarithmic
scaling on the y axis |
| |
'NoCursor' |
cursor objects are hidden by default, but may be
re-enabled with the command
plt('cursor',get(gca,'user'),'set','visON'); |
| |
'-Help' /
'+Help' |
removes/adds the Help tag from the menu box |
| |
'-Mark' /
'+Mark' |
removes/adds the Mark tag from the menu box |
| |
'-Xlog' /
'+Xlog' |
removes/adds the LinX/LogX tag from the menu box |
| |
'-Ylog' /
'+Ylog' |
removes/adds the LinY/LogY tag from the menu box |
| |
'-Print' /
'+Print' |
removes/adds the Print tag from the menu box |
| |
'-Grid' /
'+Grid' |
removes/adds the Grid tag from the menu box |
| |
'-Figmenu' /
'+Figmenu' |
removes/adds the Menu tag from the menu box |
| |
'-Rotate' /
'+Rotate' |
removes/adds the XYrotate (XY↔)
tag from the menu box |
| |
'-All' /
'+All' |
removes /adds all menu box items |
These options strings are case sensitive. The first letter must be a
capital and the rest lower case as shown. For example if you wanted the
display to initialize with the menu bar enabled and the grid lines off you
could use either:
plt(...,'Options','Menu','Options','Ticks');
plt(...,'Options','Menu Ticks');
If you even wanted to prevent the user from re-enabling the grid
lines by using the menu box you would use:
plt(...,'Options','Menu Ticks -Grid');
Instead of a space between the options, you can use any separator
character you like. In fact plt really only looks at the capital letters so
if you wanted to be very concise (not to mention cryptic), the previous
command could be written:
plt(...,'Options','MT-G');
You can also use a plus sign on the menu box tags.
For example, both of the following commands would remove all the menu box
items except for the x and y axis lin/log controls:
plt(...,'Options','-H-M-G-F');
plt(...,'Options','+X+Y');
Note that the Print menu box tag is unique in that it is off by
default and will only appear when +P appears in
the Options string. If you remove all menu box items (i.e.
'Options','-A'), the box outline is not
displayed.
