Text Labels Dialog
Text may be written on the graphics window by the using the
Label dialog or with the LABEL command.
The dialog is invoked by the Label item
in the Graphics Menu or by the
graphics window context menu.
If from the latter, the Position
fields correspond to the point at which the right mouse button was clicked.
The Position fields are the location of
the top left corner of the text in units of percents of the subwindow.
(The units used with the LABEL
command are fractions---0 to 1---of the subwindow dimensions.)
X is the distance from the
left side of the subwindow and Y
is the position from the bottom.
Typing in the fields changes the values,
as does clicking on the arrows next to the edit field.
- X is / Y is
The choices in the X is and
Y is boxes tell how the
Position is interpreted for placement of the text.
- Label String
The text in the Label
String field is what will appear on the plot.
The Preview button shows the label
without committing it to the plot. (It draws the label on the screen,
but not in the backing store bitmap; the label does not appear when
the bitmap is copied to the screen.)
The previewed label is automatically updated when the
Position values are changed.
Sabrina, rather than the window manager,
must implement backing store for the preview feature to work correctly.
If necessary, include the resource
Clear removes the
previewed label from the screen plot.
Apply commits the label to the plot
(after which it cannot be Cleared
or altered by changing values on the dialog) and dismisses the dialog.
Cancel clears any previewed label and dismisses
The font used for the labels (and for the numbers in color legend bars)
is taken from the resource
Executing xlsfonts at the shell prompt provides a list of available fonts.
