PURPOSE

A class for creating single-plot Gnuplot objects, i.e., objects for creating Gnuplot plots in a single-plot mode (for multiplot-mode, see the ::pwtk::gp::multiplot class).

EXAMPLE

    # create with Gnuplot a PNG image of sin(x) function
    
    set obj [::pwtk::gp::plot new sin.png]
    
    $obj options {
           xlabel {'x'}
           ylabel {'sin(x)'}
    }
    $obj options {
           xzeroaxis {lt -1}
    }
    $obj unset key grid
    $obj plot { [-pi:pi] sin(x) }
    
    $obj exec; # this executes Gnuplot and creates sin.png image
