You could run wee_reports, using a timestamp of a year ago, saving the images to a separate spot. Then you would be able to display this month's graph, and the same month a year ago. But, they would be in separate graphs. -tk On Thu, Feb 9, 2017 at 3:54 PM, Thomas Carlin <thomascarl...@gmail.com> wrote: > I have a couple questions about image generation that doesn't seem to be > covered in the docs anywhere. > > I would like to be able to create images with the same data value, but > from multiple time ranges.
