Why not use the actual month? With a simple x/y canvas in Tkinter you could plot by the months with polygon coordinates as your data visualization, or in 30 day /etc windows, just the price(y) being a derivative of x(the frequency of changes), and create simple line segments with polygon coordinat

You could also begin a little stats(I think steven D'aprano did pystats), which would show rhythms within those particular frequency windows, using y as a basis for your model On Sat, Jul 20, 2013 at 1:10 AM, David Hutto wrote: > Why not use the actual month? With a simple x/y canvas in Tkinter
