Simple widget to display a Matplotlib Figure in kivy. Also a basic toolbar widget to pan and zoom the plot. Android/IOS not supported (until matplotlib can be ported to those systems)
Basic example
import matplotlib as mpl from kivy_matplotlib import MatplotFigure from kivy.base import runTouchApp # Make plot fig = mpl.figure.Figure(figsize=(2, 2)) fig.gca().plot([1, 2, 3]) # MatplotFigure (Kivy widget) fig_kivy = MatplotFigure(fig) runTouchApp(fig_kivy)
Example with Toolbar
import matplotlib as mpl
from kivy.app import App
import numpy as np
from kivy.lang import Builder
from kivy_matplotlib import MatplotFigure, MatplotNavToolbar
kv = """
BoxLayout:
orientation: 'vertical'
MatplotFigure:
id: figure_wgt
size_hint: 1, 0.7
MatplotNavToolbar:
id: navbar_wgt
size_hint: 1, 0.3
figure_widget: figure_wgt
"""
class testApp(App):
title = "Test Matplotlib"
def build(self):
# Matplotlib stuff, figure and plot
fig = mpl.figure.Figure(figsize=(2, 2))
t = np.arange(0.0, 100.0, 0.01)
s = np.sin(0.08 * np.pi * t)
axes = fig.gca()
axes.plot(t, s)
axes.set_xlim(0, 50)
axes.grid(True)
# Kivy stuff
root = Builder.load_string(kv)
figure_wgt = root.ids['figure_wgt'] # MatplotFigure
figure_wgt.figure = fig
return root
testApp().run()
