Saving Plots to Files

Any of the above plotting utilities can also be used for directly plotting into eps or png files, or pdf files if your gnuplot installation allows. A final gnuplot.plotflush() command ensures that all output is written to the file properly.

gnuplot.epsfigure('test.eps')
gnuplot.plot({'Sin Curve',torch.sin(torch.linspace(-5,5))})
gnuplot.xlabel('X')
gnuplot.ylabel('Y')
gnuplot.plotflush()

gnuplot.epsfigure(fname)

Creates a figure directly on the eps file given with fname. This uses Gnuplot terminal postscript eps enhanced color.

gnuplot.pdffigure(fname)

Only available if your installation of gnuplot has been compiled with pdf support enabled.

Creates a figure directly on the pdf file given with fname. This uses Gnuplot terminal pdf enhanced color, or pdfcairo enhanced color if available.

gnuplot.pngfigure(fname)

Creates a figure directly on the png file given with fname. This uses Gnuplot terminal png, or pngcairo if available.

gnuplot.svgfigure(fname)

Creates a figure directly on the svg file given with fname. This uses Gnuplot terminal svg.

gnuplot.figprint(fname)

Prints the current figure to the given file with name fname. Only png or eps files are supported by default. If your gnuplot installation allows, pdf files are also supported.

gnuplot.plotflush([n])

This command sends unset output to underlying gnuplot. Useful for flushing file based terminals.

gnuplot.close()

Closes open file handles. Prevents too many handles staying open if creating lots of plots.
