    jpeg_quality
            Same as "PerlSetVar JpegQuality". A number from 0 to 100
            that determines the jpeg quality and the size. If not set at
            all, the GD library will determine the optimal setting.
            Changing this value doesn't seem to do much as far as line
            graphs go, but YMMV.

    background_image
            Set an image as the background for the graph. You are
            responsible for choosing a sane image to go with your graph,
            the background should be either transparent or the same
            color you will use. This is the same as using the "logo"
            parameter with an image of the same size as the graph,
            except this option will resize the image if necessary,
            making it more convenient for this purpose. The file or URL
            can be of any type your copy of GD supports.

    captionN
            Draws a character string using a TrueType font at an
            arbitrary location. Takes an array of
            "($fgcolor,$fontname,$ptsize,$angle,$x,$y,$string[,$box_colo
