22.214.171.124 Gnuplot Invocation
Using `Edit => Preferences => Helpers => Plot', you can choose the
Gnuplot program to invoke. This is tied to the following resource:
-- Resource: plotCommand (class PlotCommand)
The name of a Gnuplot executable. Default is `gnuplot', followed
by some options to set up colors and the initial geometry.
Using `Edit => Preferences => Helpers => Plot Window', you can
choose whether to use the Gnuplot plot window (`External') or to use
the plot window supplied by DDD (`builtin'). This is tied to the
-- Resource: plotTermType (class PlotTermType)
The Gnuplot terminal type. Can have one of two values:
* If this is `x11', DDD "swallows" the _external_ Gnuplot
output window into its own user interface. Some window
managers, notably `mwm', have trouble with swallowing
* Setting this resource to `xlib' (default) makes DDD provide a
_builtin plot window_ instead. In this mode, plots work well
with any window manager, but are less customizable (Gnuplot
resources are not understood).
You can further control interaction with the external plot window:
-- Resource: plotWindowClass (class PlotWindowClass)
The class of the Gnuplot output window. When invoking Gnuplot,
DDD waits for a window with this class and incorporates it into
its own user interface (unless `plotTermType' is `xlib'; see
above). Default is `Gnuplot'.
-- Resource: plotWindowDelay (class WindowDelay)
The time (in ms) to wait for the creation of the Gnuplot window.
Before this delay, DDD looks at each newly created window to see
whether this is the plot window to swallow. This is cheap, but
unfortunately, some window managers do not pass the creation event
to DDD. If this delay has passed, and DDD has not found the plot
window, DDD searches _all_ existing windows, which is pretty
expensive. Default time is `2000'.
