Therefore, in order to obtain a useful plot, the characteristics of the graphics device in use have to be known in advance. MIDAS can run on various combinations of alpha-numerical terminals, image display systems and graphic devices. How to specify the graphic output device for these possibilities is described below. <P> If you are using the standard MIDAS configuration (alpha-numerical and graphic terminal together with an image display), the MIDAS start-up procedure MIDAS takes care of the proper assignment. If you want to obtain graphic output on a workstation running under X-Windows you have to issue the command <TT> CREATE/GRAPHIC</TT><A NAME="8112"> </A>. This command creates a window on the workstation where subsequent plot and overplot commands will write. Up to 4 graphic windows can be created this way. Removal of a window can be done with <TT> DELETE/GRAPHIC</TT><A NAME="8114"> </A>. <P> To get plot output on a graphics device (the graphic terminal included), a proper assignment for that device has to be done in advance. Obviously, the assignment depends on the type of device in use and hence may differ from system to system. If your institute mainly uses graphic terminals of brand ``abc'', life would be much simpler if this device were the default one and therefore the assignment to be included in the MIDAS startup procedure. You can ask your local MIDAS support to do so. The assignment to be made is: <UL> <LI>for VAX/VMS systems: <TT>ASSIGN</TT> <I>AGL_type</I> <TT>AGL3DEV</TT>; <A NAME="8119"> </A> <LI>for UNIX systems (C-Shell): <TT>setenv</TT> <TT>AGL3DEV</TT> <I>AGL_type</I>; <LI>for UNIX systems (Bourne-Shell): <TT>AGL3DEV</TT>=<I>AGL_type</I>. </UL> Changing the assignment from the default device to another one can always been done in the <TT>login.prg</TT><A NAME="8127"> </A> file (see Chapter <A HREF="node22.html#monitor-and-syntax">3</A>). This of course would be useful if a particular device is not assigned by the MIDAS startup procedure but is used regularly. Finally, if you run MIDAS from a stand-alone (non-graphic) terminal, an assignment to the NULL device <A NAME="8129"> </A> or to the postscript device can be made. In the first case only a graphic meta file will be created; in the later case a postscript file. In case of problems consult your local MIDAS support or your system manager. <P> Table <A HREF="node86.html#supported-devices">6.1</A> contains the most commonly used graphics devices (the <I>AGL_type</I>'s) currently supported by MIDAS. <BR> <DIV ALIGN="CENTER"><A NAME="8310"> </A> <TABLE> <CAPTION><STRONG>Table 6.1:</STRONG> Supported Devices</CAPTION> <TR><TD> <DIV ALIGN="CENTER"> <TABLE CELLPADDING=3 BORDER="1" ALIGN="CENTER"> <TR><TD ALIGN="LEFT"><B> Device Identification</B></TD> <TH ALIGN="LEFT"><B>AGL_type </B></TH> </TR> <TR><TD ALIGN="LEFT">DEC VT125 terminal</TD> <TD ALIGN="LEFT">vt125</TD> </TR> <TR><TD ALIGN="LEFT">DEC VT240 terminal</TD> <TD ALIGN="LEFT">vt125</TD> </TR> <TR><TD ALIGN="LEFT">DEC VT125 terminal with Retrogr.</TD> <TD ALIGN="LEFT">tkg.vt640</TD> </TR> <TR><TD ALIGN="LEFT">DEC VT100 terminal with Retrogr.</TD> <TD ALIGN="LEFT">tkg.vt640</TD> </TR> <TR><TD ALIGN="LEFT">CIT101 with CIG 201 card</TD> <TD ALIGN="LEFT">tkg.cit101</TD> </TR> <TR><TD ALIGN="LEFT">GraphOn GO-250</TD> <TD ALIGN="LEFT">tkg.vt640</TD> </TR> <TR><TD ALIGN="LEFT">HDS 2200</TD> <TD ALIGN="LEFT">tkg.hds22</TD> </TR> <TR><TD ALIGN="LEFT">HPGL plotters</TD> <TD ALIGN="LEFT">hpgl</TD> </TR> <TR><TD ALIGN="LEFT">LN03 plus laser printer</TD> <TD ALIGN="LEFT">tkg.ln03</TD> </TR> <TR><TD ALIGN="LEFT">Tektronix 4010</TD> <TD ALIGN="LEFT">tkg.t4010</TD> </TR> <TR><TD ALIGN="LEFT">Tektronix 4014</TD> <TD ALIGN="LEFT">tkg.t4014</TD> </TR> <TR><TD ALIGN="LEFT">Tektronix 4100 series</TD> <TD ALIGN="LEFT">tkg.t4100</TD> </TR> <TR><TD ALIGN="LEFT">QMS laser printer</TD> <TD ALIGN="LEFT">tkg.qms</TD> </TR> <TR><TD ALIGN="LEFT">X-Windows</TD> <TD ALIGN="LEFT">idi</TD> </TR> <TR><TD ALIGN="LEFT">Apple Laser Writer</TD> <TD ALIGN="LEFT">pscript</TD> </TR> <TR><TD ALIGN="LEFT">Postscript printers</TD> <TD ALIGN="LEFT">pscript</TD> </TR> <TR><TD ALIGN="LEFT">Postscript file</TD> <TD ALIGN="LEFT">pscript</TD> </TR> <TR><TD ALIGN="LEFT">Versatec V-80</TD> <TD ALIGN="LEFT">raster</TD> </TR> <TR><TD ALIGN="LEFT">Raster devices</TD> <TD ALIGN="LEFT">raster</TD> </TR> <TR><TD ALIGN="LEFT">Null device</TD> <TD ALIGN="LEFT">null</TD> </TR> </TABLE></DIV> <A NAME="supported-devices"> </A> </TD></TR> </TABLE> </DIV> <BR> <P> <HR> <!--Navigation Panel--> <A NAME="tex2html1608" HREF="node87.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="icons.gif/next_motif.gif"></A> <A NAME="tex2html1604" HREF="node84.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="icons.gif/up_motif.gif"></A> <A NAME="tex2html1598" HREF="node85.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="icons.gif/previous_motif.gif"></A> <A NAME="tex2html1606" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="icons.gif/contents_motif.gif"></A> <A NAME="tex2html1607" HREF="node216.html"> <IMG WIDTH="43" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="index" SRC="icons.gif/index_motif.gif"></A> <BR> <B> Next:</B> <A NAME="tex2html1609" HREF="node87.html">General Commands</A> <B> Up:</B> <A NAME="tex2html1605" HREF="node84.html">Graphic Facilities</A> <B> Previous:</B> <A NAME="tex2html1599" HREF="node85.html">Introduction</A> <!--End of Navigation Panel--> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-09</I> </ADDRESS> </BODY> </HTML>
