ERRO TRYING TO RUN the example

[NervenCid]

Hello:

I tried to run the code you provided:

import matplotlib
matplotlib.use('module://kivy.garden.matplotlib.backend_kivy')
from matplotlib.figure import Figure
from numpy import arange, sin, pi
from kivy.app import App

import numpy as np
from kivy.garden.matplotlib.backend_kivyagg import FigureCanvas,
NavigationToolbar2Kivy
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.boxlayout import BoxLayout
from matplotlib.transforms import Bbox
from kivy.uix.button import Button
from kivy.graphics import Color, Line, Rectangle

import matplotlib.pyplot as plt

def press(event):
print('press released from test', event.x, event.y, event.button)

def release(event):
print('release released from test', event.x, event.y, event.button)

def keypress(event):
print('key down', event.key)

def keyup(event):
print('key up', event.key)

def motionnotify(event):
print('mouse move to ', event.x, event.y)

def resize(event):
print('resize from mpl ', event.width, event.height)

def scroll(event):
print('scroll event from mpl ', event.x, event.y, event.step)

def figure_enter(event):
print('figure enter mpl')

def figure_leave(event):
print('figure leaving mpl')

def close(event):
print('closing figure')

N = 5
menMeans = (20, 35, 30, 35, 27)
menStd = (2, 3, 4, 1, 2)

ind = np.arange(N) # the x locations for the groups
width = 0.35 # the width of the bars

fig, ax = plt.subplots()
fig2, ax2 = plt.subplots()
rects1 = ax.bar(ind, menMeans, width, color='r', yerr=menStd)

womenMeans = (25, 32, 34, 20, 25)
womenStd = (3, 5, 2, 3, 3)
rects2 = ax.bar(ind + width, womenMeans, width, color='y', yerr=womenStd)

add some text for labels, title and axes ticks

ax.set_ylabel('Scores')
ax.set_title('Scores by group and gender')
ax.set_xticks(ind + width)
ax.set_xticklabels(('G1', 'G2', 'G3', 'G4', 'G5'))
ax.legend((rects1[0], rects2[0]), ('Men', 'Women'))

rects2 = ax2.bar(ind + width, womenMeans, width, color='y', yerr=womenStd)

def autolabel(rects):
# attach some text labels
for rect in rects:
height = rect.get_height()
ax.text(rect.get_x() + rect.get_width() / 2., 1.05 * height,
'%d' % int(height), ha='center', va='bottom')

fig.canvas.mpl_connect('button_press_event', press)
fig.canvas.mpl_connect('button_release_event', release)
fig.canvas.mpl_connect('key_press_event', keypress)
fig.canvas.mpl_connect('key_release_event', keyup)
fig.canvas.mpl_connect('motion_notify_event', motionnotify)
fig.canvas.mpl_connect('resize_event', resize)
fig.canvas.mpl_connect('scroll_event', scroll)
fig.canvas.mpl_connect('figure_enter_event', figure_enter)
fig.canvas.mpl_connect('figure_leave_event', figure_leave)
fig.canvas.mpl_connect('close_event', close)

fig2.canvas.mpl_connect('button_press_event', press)
fig2.canvas.mpl_connect('button_release_event', release)
fig2.canvas.mpl_connect('key_press_event', keypress)
fig2.canvas.mpl_connect('key_release_event', keyup)
fig2.canvas.mpl_connect('motion_notify_event', motionnotify)
fig2.canvas.mpl_connect('resize_event', resize)

fig2.canvas.mpl_connect('figure_enter_event', figure_enter)
fig2.canvas.mpl_connect('figure_leave_event', figure_leave)
fig2.canvas.mpl_connect('close_event', close)

canvas = fig.canvas

canvas.blit(Bbox(np.array([[0, 0], [400, 400]], np.int32)))

canvas2 = fig2.canvas

def callback(instance):
autolabel(rects1)
autolabel(rects2)
canvas.draw()

class MatplotlibTest(App):
title = 'Matplotlib Test'

def build(self):
    fl = BoxLayout(orientation="vertical")
    a = Button(text="press me", height=40, size_hint_y=None)
    a.bind(on_press=callback)
    nav1 = NavigationToolbar2Kivy(canvas)
    nav2 = NavigationToolbar2Kivy(canvas2)
    fl.add_widget(nav1.actionbar)
    fl.add_widget(canvas)
    fl.add_widget(nav2.actionbar)
    fl.add_widget(canvas2)
    fl.add_widget(a)
    return fl

if name == 'main':
MatplotlibTest().run()

And i got:

Whats wrong? Do i need additional packages?

Thank you

Please see the garden docs: https://kivy.org/docs/api-kivy.garden.html. You need to install the garden flowers before you can use it. Also, github issues are for bug reports, not for support request. Please use the kivy users mailing list or IRC #kivy for that.
