4.11 Landscape and Portrait Orientations
</H1>
<A NAME="4575"></A>

<P>
In general, a plot has an <I>x</I>-axis increasing from left to
right and a <I>y</I>-axis increasing from bottom to top. If the
paper is turned so that the long dimension of the paper is
parallel to the <I>x</I>-axis then the plot is said to have
<I>Landscape</I> orientation. If the long dimension of
the paper parallels the <I>y</I>-axis the orientation is called
<I>Portrait</I>. (Think of taking pictures with a camera
and these words make sense). All the programs in <A NAME="tex2html251"
HREF="http://www.soest.hawaii.edu/gmt"><B>GMT</B></A> have the
same default orientation, which is Landscape. Use <B>-P</B> to
change to Portrait (Note that PAPER_MEDIA is a user-definable
parameter, by default set to Letter (or A4). For other paper
dimensions you must change this value accordingly).
