SetPrintImage — Determine whether or not to automatically output the image when the plot is drawn
$plot->SetPrintImage($pi)
SetPrintImage determines whether or not to automatically
output the image (as if PrintImage was used) when a plot
is drawn (with DrawGraph). The default is True.
$piTrue to have DrawGraph automatically print (output) the image, False to prevent DrawGraph from outputting the image.
When putting multiple plots on one image, is is necessary to use
SetPrintImage(False) to defer output of the image
until after all the plots have been drawn.
See Section 4.8, “Multiple Plots Per Image” for more information on putting
multiple plots on an image.
Calling SetPrintImage(False) is also needed when using
EncodeImage to return the image data (rather than sending
it to standard output or to a file).
