# Interface to the Gnuplot interpreter

class `sage.interfaces.gnuplot.``Gnuplot`

  Bases: `sage.structure.sage_object.SageObject`

  Interface to the Gnuplot interpreter.

  `console`()

    x.__init__(...) initializes x; see help(type(x)) for signature

  `gnuplot`()

    x.__init__(...) initializes x; see help(type(x)) for signature

  `interact`(cmd)

    x.__init__(...) initializes x; see help(type(x)) for signature

  `plot`(cmd, file=None, verbose=True, reset=True)

    Draw the plot described by cmd, and possibly also save to an eps or png file.

    INPUT:

    - `cmd` - string
    - `file` - string (default: None), if specified save plot to given file, which may be either an eps (default) or png file.
    - `verbose` - print some info
    - `reset` - True: reset gnuplot before making graph

    OUTPUT: displays graph

    Note

    Note that `^` s are replaced by `**` s before being passed to gnuplot.

  `plot3d`(f, xmin=-1, xmax=1, ymin=-1, ymax=1, zmin=-1, zmax=1, title=None, samples=25, isosamples=20, xlabel='x', ylabel='y', interact=True)

    x.__init__(...) initializes x; see help(type(x)) for signature

  `plot3d_parametric`(f='cos(u)*(3 + v*cos(u/2)), sin(u)*(3 + v*cos(u/2)), v*sin(u/2)', range1='[u=-pi:pi]', range2='[v=-0.2:0.2]', samples=50, title=None, interact=True)

    Draw a parametric 3d surface and rotate it interactively.

    INPUT:

    - `f` - (string) a function of two variables, e.g., ‘cos(u)*(3 + v*cos(u/2)), sin(u)*(3 + v*cos(u/2)), v*sin(u/2)’
    - `range1` - (string) range of values for one variable, e.g., ‘[u=-pi:pi]’
    - `range2` - (string) range of values for another variable, e.g., ‘[v=-0.2:0.2]’
    - `samples` - (int) number of sample points to use
    - `title` - (string) title of the graph.

    EXAMPLES:

        sage: gnuplot.plot3d_parametric('v^2*sin(u), v*cos(u), v*(1-v)')   # optional - gnuplot  (not tested, since something pops up).

`sage.interfaces.gnuplot.``gnuplot_console`()

  x.__init__(...) initializes x; see help(type(x)) for signature
