⎕PLOT

[hudson]

Hi.

A few things about ⎕plot:

1) GNU APL info manual says (2.31):
   ⎕PLOT ¯3      ⍝ close all plot windows    

However:
      ⎕plot 2 1 4 3
94820426042176
      ⎕plot ¯3
*** Could not find w_props 0xfffffffffffffffd in plot_stop() ***
0

[After that, further ⎕plot calls randomly display older plot data, if any.]


2) Is there any way to reuse on the same plot window (instead of
storing/closing the handle and creating a new plot window every time)?
(Likewise the default "plot()" behaviour of GNU Octave.)


3) Info manual (2.31.3) says that a plot can be closed "by opening the
drop down menu of the window (at the top left of the window)",
but that seems to be system-specific. Here, I can find a similar menu
but right-clicking the window-manager border at the top of the window.
