Graphics?

Try this

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

   There are no library operations named ** 
      Use HyperDoc Browse or issue
                                 )what op **
      to learn if there is any operation containing " ** " in its name.

   Cannot find a definition or applicable library operation named ** 
      with argument type(s) 
                                 Variable(x)
                               PositiveInteger

      Perhaps you should use "@" to indicate the required return type, 
      or "$" to specify which version of the function you need.

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

   )library cannot find the file 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")

   There are no library operations named ** 
      Use HyperDoc Browse or issue
                                 )what op **
      to learn if there is any operation containing " ** " in its name.

   Cannot find a definition or applicable library operation named ** 
      with argument type(s) 
                                 Variable(x)
                               PositiveInteger

      Perhaps you should use "@" to indicate the required return type, 
      or "$" to specify which version of the function you need.

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}
