DERIVED FROM

::pwtk::gp::plot

PURPOSE

A class for creating 'splot' Gnuplot objects, i.e., objects for creating Gnuplot 3D surface and/or heatmap plots in a single-plot mode. It is derived from the ::pwtk::gp::plot class, implying that the methods of ::pwtk::gp::plot can be used.

By default, a heatmap is created.

EXAMPLE

    # create with Gnuplot a PNG heatmap image of the sin(x*y) function
    
    set obj [::pwtk::gp::splot new -type map -t "a simple plot" sin.png]
    
    $obj options {
       xlabel 'x'
       ylabel 'y'
       xrange [-pi:pi]
       yrange [-pi:pi]
    }
    $obj plot sin(x*y)
    
    $obj exec; # this executes Gnuplot and creates the 'sin.png' PNG image
