With the exception of the masks and catalogues, the plot package is able to plot the data stored in these structures. Data can be plotted with <TT>PLOT/</TT> as well as with <TT>OVERPLOT/</TT> commands. In the first case, MIDAS will start a complete new plot (<I>e.g.</I> a graphic terminal screen will be erased and old plotfiles will be deleted); in the latter one MIDAS will extend the existing plot information without erasing the results of previous plot commands. <P> In addition of the plot commands that enable the user to plot data command are available to produce coordinate box(es) within subsequently data can be overplotted, and commands to add text, symbols, and (grid) lines. An overview of the commands is given below. <TABLE CELLPADDING=3> <TR><TD ALIGN="LEFT"><TT> PLOT/AXES</TT></TD> <TD ALIGN="LEFT">plot a box with tick marks, tick labels and axes labels</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/AXES</TT></TD> <TD ALIGN="LEFT">overplot a box with tick marks, tick labels and axes labels</TD> </TR> <TR><TD ALIGN="LEFT"> </TD> <TD ALIGN="LEFT"> </TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/CONTOUR</TT></TD> <TD ALIGN="LEFT">plot contours of a two-dimensional image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/CONTOUR</TT></TD> <TD ALIGN="LEFT">overplot contours of a two-dimensional image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/COLUMN</TT></TD> <TD ALIGN="LEFT">plot a column of an image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/COLUMN</TT></TD> <TD ALIGN="LEFT">overplot a column of an image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/DESCRIPTOR</TT></TD> <TD ALIGN="LEFT">plot an entry in a descriptor</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/DESCRIPTOR</TT></TD> <TD ALIGN="LEFT">overplot an entry in a descriptor</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/GRAY</TT></TD> <TD ALIGN="LEFT">plot gray scale map of a two-dimensional image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/GRAY</TT></TD> <TD ALIGN="LEFT">overplot gray scale map of a two-dimensional image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/HISTOGRAM</TT></TD> <TD ALIGN="LEFT">plot a histogram of a table column or image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/HISTOGRAM</TT></TD> <TD ALIGN="LEFT">overplot a histogram of a table column or image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/KEYWORD</TT></TD> <TD ALIGN="LEFT">plot the contents of a keyword</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/KEYWORD</TT></TD> <TD ALIGN="LEFT">overplot the contents of a keyword</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/PERSPECTIVE</TT></TD> <TD ALIGN="LEFT">perspective plotting (3-dim.) of an image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/ROW</TT></TD> <TD ALIGN="LEFT">plot a row (line) of an image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/ROW</TT></TD> <TD ALIGN="LEFT">overplot a row (line) of an image</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/TABLE</TT></TD> <TD ALIGN="LEFT">plot table data</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/TABLE</TT></TD> <TD ALIGN="LEFT">overplot table data</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/ERROR</TT></TD> <TD ALIGN="LEFT">overplot table column containing errors</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PLOT/VECTOR</TT></TD> <TD ALIGN="LEFT">plot vector map from two 2-dim. images with smoothing option</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/VECTOR</TT></TD> <TD ALIGN="LEFT">overplot vector map from two 2-dim. images with smoothing option</TD> </TR> <TR><TD ALIGN="LEFT"> </TD> <TD ALIGN="LEFT"> </TD> </TR> <TR><TD ALIGN="LEFT"><TT> LABEL/GRAPHIC</TT></TD> <TD ALIGN="LEFT">plot text in an existing plot</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/LINE</TT></TD> <TD ALIGN="LEFT">overplot a line in an existing plot</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/SYMBOL</TT></TD> <TD ALIGN="LEFT">overplot a symbol in an existing plot</TD> </TR> <TR><TD ALIGN="LEFT"><TT> OVERPLOT/GRID</TT></TD> <TD ALIGN="LEFT">overplot a grid, by connecting tickmarks</TD> </TR> </TABLE> <P> <BR><HR> <!--Table of Child-Links--> <A NAME="CHILD_LINKS"> </A> <UL> <LI><A NAME="tex2html1658" HREF="node91.html">Plotting and overplotting axes</A> <LI><A NAME="tex2html1659" HREF="node92.html"><TT>PLOT</TT> and <TT>OVERPLOT</TT> commands for plotting data</A> <LI><A NAME="tex2html1660" HREF="node93.html">Plotting text, symbols, and lines</A> </UL> <!--End of Table of Child-Links--> <HR> <!--Navigation Panel--> <A NAME="tex2html1656" HREF="node91.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="icons.gif/next_motif.gif"></A> <A NAME="tex2html1652" HREF="node84.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="icons.gif/up_motif.gif"></A> <A NAME="tex2html1646" HREF="node89.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="icons.gif/previous_motif.gif"></A> <A NAME="tex2html1654" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="icons.gif/contents_motif.gif"></A> <A NAME="tex2html1655" 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="tex2html1657" HREF="node91.html">Plotting and overplotting axes</A> <B> Up:</B> <A NAME="tex2html1653" HREF="node84.html">Graphic Facilities</A> <B> Previous:</B> <A NAME="tex2html1647" HREF="node89.html">ASSIGN/GRAPHIC and COPY/GRAPHIC</A> <!--End of Navigation Panel--> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-09</I> </ADDRESS> </BODY> </HTML>
