Method: GnuplotRB::Plottable#to_specific_term

Defined in:
lib/gnuplotrb/mixins/plottable.rb

#to_specific_term(terminal, path = nil, **options) ⇒ Object

Output plot to specific terminal (possibly some file). Explicit use should be avoided. This method is called from #method_missing when it handles method names like #to_png(options).

Examples:

## plot here may be Plot, Splot, Multiplot or any other plottable class
plot.to_png('./result.png', size: [300, 500])
contents = plot.to_svg(size: [100, 100])
plot.to_dumb('./result.txt', size: [30, 15])

Parameters:

  • trminal (String) —

    terminal name (‘png’, ‘svg’ etc)

  • path (String) (defaults to: nil) —

    path to output file, if none given it will output to temp file and then read it and return binary contents of file

  • options (Hash) —

    used in #plot
