<h3>9.3.48: `<font color="#82140F"><code>state</code></font>'</h3>
<!-- latex: \index{@code{state} command} -->
<TABLE SUMMARY="Example" BORDER="0" BGCOLOR="#efefef" WIDTH="100%">
<TR>
<TD>
<PRE>
<font color="#82140F">
`state save|restore|display'
</font></PRE>
</TD>
</TR>
</TABLE>
<p>
The `<font color="#82140F"><code>save</code></font>' operation pushes a record of the graphics state (pen and
font characteristics, margins, axis lengths, min/max/inc values on axes,
etc) onto a stack. The `<font color="#82140F"><code>restore</code></font>' operation replaces the present
state with whatever is on top of the stack, and then pops the stack.
Use `<font color="#82140F"><code>display</code></font>' to see some of the state properties.
<p>
The `<font color="#82140F"><code>state</code></font>' command is useful for temporary changes of axis
properties, etc.
<p>
BUG: only line characteristics (width, color) and font characteristics
(font, size, color) are saved so far. In fact, the full list of what
should be saved has not yet been finalized by the author.
