Django-dataplot Code

Django-dataplot is general enough to accomodate any image generation
program that makes an image on the local filesystem. Currently
supported plotting backends are R and matplotlib, but there's nothing
to stop you from writing your own backend for your statistical
plotting language of choice.

- Create a subclass of dataplot.GenericPlot.

- Your subclass needs to define (from GenericPlot docstring):

    convert_to: dictionary that defines associated file suffixes, i.e.
    convert_to={
        'png':{'suffix':'.png'},
        'thumb':{'suffix':'-thumb.png','convert_args':'-resize 65x90'},
        'pdf':{'suffix':'.pdf'},
        }
        
    convert_from: one of the keys from convert_to, which specifies
    which of the files is created by the makefile method.
    
    makefile: a method that creates the image specified by
    convert_from on the filesystem.

- Your plotting program in the makefile method will need to know what
  file to write to. You can get its full pathname by calling
  self.from_filename(), where self is your Plot instance.

- Thats basically it. Just make sure the convert_from file (pdf in
  this case) is generated after your makefile method is called, and
  dataplot will take care of the rest.
