[Matplotlib-users] matploltib use gpu ?

[nice]

My problem: I have about 10 million point to plot.

with this example, moving in the graph is very slow.
Is there a way to have an intelligent zoom which removes invisible items on
the eye?



import matplotlib
matplotlib.use('TkAgg')
import numpy
from numpy import arange, sin, pi
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg,
NavigationToolbar2TkAgg
from matplotlib.figure import Figure
import tkinter as Tk

root = Tk.Tk()
root.wm_title("Embedding in TK")


f = Figure(figsize=(5, 4), dpi=100)
a = f.add_subplot(111)


t = arange(0.0, 10000000, 1)
s = arange(0.0, 10000000, 1)
a.plot(t, s)


canvas = FigureCanvasTkAgg(f, master=root)
canvas.show()
canvas.get_tk_widget().pack(side=Tk.TOP, fill=Tk.BOTH, expand=1)

toolbar = NavigationToolbar2TkAgg(canvas, root)
toolbar.update()
canvas._tkcanvas.pack(side=Tk.TOP, fill=Tk.BOTH, expand=1)


def _quit():
    root.quit()
    root.destroy()

button = Tk.Button(master=root, text='Exit', command=_quit)
button.pack(side=Tk.BOTTOM)

Tk.mainloop()
