to Kivy users support
i want to use matplotlib.pyplot in my code. a simplified code follows:
vqcia.py:
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.anchorlayout import AnchorLayout
from kivy.properties import ObjectProperty
import matplotlib.pyplot as plt
class VQCIA(BoxLayout):
# Connects the value in the TextInput widget to these
# fields
goi = ObjectProperty()
def submit_goi(self):
# Get the student name from the TextInputs
goi = self.goi.text
plt.plot([1,2,3,4])
plt.show()
return
class VQCIAApp(App):
def build(self):
root = AnchorLayout(anchor_x='center', anchor_y='center')
root.add_widget(VQCIA())
return root
if __name__ == '__main__':
VQCIAApp().run()VQCIA.kv:
# ---------- VQCIA.kv ----------
VQCIA:
<VQCIA>:
orientation: "vertical"
goi: goi
padding: dp(10)
spacing: dp(10)
size: dp(400), dp(200)
pos: dp(200), dp(200)
size_hint:None,None
BoxLayout:
Label:
text: "Enter gene of interest with TAIR ID:"
font_size: '25sp'
BoxLayout:
TextInput:
hint_text: 'AT3G20770'
multiline: False
font_size: '25sp'
id: goi
BoxLayout:
Button:
text: "Submit"
size_hint_x: 15
on_press: root.submit_goi() while my lab computer is macOS Sierra 10.12.6 with Kivy==1.10.1 and matplotlib==2.1.0 and has ideal output:
but my personal computer with macOS high Sierra 10.13.6 with Kivy==1.10.1 and matplotlib==2.1.0 fails with following error:
