Create a GUI by connecting quibs with widgets

A simple demo of a quib-linked GUI with matplotlib.widgets.slider.

• Features:

  • Quib-linked widgets

  • Inverse assignments

from pyquibbler import iquib, initialize_quibbler
initialize_quibbler()
import matplotlib.pyplot as plt
from matplotlib.widgets import Slider
import numpy as np
%matplotlib tk

# Figure setup:
fig = plt.figure(figsize=(4, 6))

axs = fig.add_axes([0, 0.36, 1, 0.64])
axs.axis('square')
axs.axis((-10, 10, -10, 10))
axs.axis('off')

axs_slider1 = fig.add_axes([0.3, 0.16, 0.55, 0.03])
axs_slider2 = fig.add_axes([0.3, 0.06, 0.55, 0.03])

# Defining quib input variables:
nPoints = iquib(120)
nCycles = iquib(30)

# Define downstream function quib calculations based on the quib inputs:
phi = np.linspace(0, 2 * np.pi * nCycles, nPoints)
r = np.linspace(0, 10, nPoints)

# Plot the data:
axs.plot(r * np.cos(phi), r * np.sin(phi), 'r-');

# Create quib-linked slider widgets:
Slider(ax=axs_slider1, label='nCycles', valmin=0, valmax=200, valstep=1, valinit=nCycles);
Slider(ax=axs_slider2, label='nPoints', valmin=0, valmax=200, valstep=1, valinit=nPoints);
