61
<p>Earlier versions of Octave provided plotting through the use of
 
62
gnuplot.  This capability is still available.  But, a newer plotting
 
63
capability is provided by access to OpenGL.  Which plotting system
 
64
is used is controlled by the <code>graphics_toolkit</code> function.
 
65
See <a href="Graphics-Toolkits.html#Graphics-Toolkits">Graphics Toolkits</a>.
 
66
</p>
 
67
<p>The function call <code>graphics_toolkit (&quot;fltk&quot;)</code> selects the
 
68
FLTK/OpenGL system, and <code>graphics_toolkit (&quot;gnuplot&quot;)</code> selects the
 
69
gnuplot system.  The two systems may be used selectively through the use
 
70
of the <code>graphics_toolkit</code> property of the graphics handle for each
 
71
figure.  This is explained in <a href="Graphics-Data-Structures.html#Graphics-Data-Structures">Graphics Data Structures</a>.
 
72
<strong>Caution:</strong> The FLTK toolkit uses single precision variables internally
 
73
which limits the maximum value that can be displayed to approximately
 
74
<em>10^{38}</em>.  If your data contains larger values you must use the gnuplot
 
75
toolkit which supports values up to <em>10^{308}</em>.
