[mgp-users-jp 00977] xsystemコマンドに関して...

[Staff user <hagihira@anes.med.osaka-u.ac.jp>]

萩平＠大阪府立羽曳野病院麻酔と申します．

magicpoint-1.09aになってから以下のサンプルのようにしてxsystemコマンド
を用いてgnuplotのグラフを画面に張り付けたところ，次のページに進んでも
グラフが消えないので困っています．1.08aまではこのようなことはありませ
んでした．
システムはFreeBSD 4.5-releaseですが，以前使用していたBSD/OS V4.0.1でも
同様の現象が生じていました．
どこに問題があるんでしょうか？
以下にtest.mgpとgnuplotのtest.pltを付けておきます．

よろしくお願いします．

--- test.mgp ---
%%%include "default.mgp"
%deffont "standard" xfont "helvetica-medium-r", vfont "goth", tfont "times.ttf"
%deffont "thick" xfont "helvetica-bold-r", vfont "goth", tfont "timesbd.ttf"

テスト１
%center
%xsystem "gnuplot -tvtwm -geometry 80x60+0+0 test.plt"

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%page
%%bgrad 
%back "blue"
%size 6, fore "yellow"

テスト２

%fore "yellow",size 5 
本来なら，これでテスト１のグラフが消えるはず...
