Graphics?

Try this

draw(5*besselJ(0,sqrt(x^2+y^2)), x=-20..20, y=-20..20);

Compiling function %B with type (DoubleFloat,DoubleFloat) -> 
      DoubleFloat 
   Transmitting data...

Not clear why latex is not rendered properly ...

The reason why this did not originally render properly was because I had not defined \axiomType as a valid LaTeX command in the LatexTemplate page. The output of the draw command generates this as part of it's LaTeX output.

Anticipating the next question:

  Where is the graphic??

Although graphics is available in the most recent version of Axiom from the Savannah CVS (see AxiomBinaries?), the problem is that graphics has not yet been integrated into MathAction. Doing so will require solving some problems about using X-windows on the MathAction server.

First load the library

)lib GDRAW

   OldGnuDraw is now explicitly exposed in frame initial 
   OldGnuDraw will be automatically loaded when needed from 
      /var/aw/var/LatexWiki/GDRAW.NRLIB/GDRAW

Now include a file name in the draw command::

gnuDraw(5*besselJ(0,sqrt(x^2+y^2)), x=-20..20, y=-20..20,"GraphicsOnMathAction1.dat")

Compiling function %C with type (DoubleFloat,DoubleFloat) -> 
      DoubleFloat

Refer to this file name when calling gnuplot:

  \begin{gnuplot}[terminal=pslatex,terminaloptions=color,scale=1.3]
  set parametric
  set hidden
  set view 20,30
  set xlabel "x"
  set ylabel "y"
  set zrange [-3:3]
  set mxtics
  set pm3d depthorder
  load "GraphicsOnMathAction1.dat"
  \end{gnuplot}
