I want to plot a line going on with a calculation. For instance: I have got a function like a,b = Update(), and just below the calculation I would like to plot the newly calculated points(a,b), what kind of lib should I use in Python?

a,b = Update()# a, b are just a float value, or maybe an array so a,b can combine to form a group of points
points(a,b)

I am a newly Python starter, so...

  • Yes, use Matplotlib. Have 2 lists with, each storing the values. When a new value is added delete the old and create a new plot with the new data and redraw the figure. Commented Nov 4, 2013 at 16:48
  • arrays don't really exist in python, use lists. Arrays do exist in Numpy (a very useful library) but they data cannot be easily appended to them. Whereas with list you can just do: a=[1,2,3]; a.append(4)` which gives [1,2,3,4]. Commented Nov 4, 2013 at 16:50
  • thanks, but ideally is to plot dynamically while getting more date of points. Is there some solution? Commented Nov 7, 2013 at 18:03
