Matplotlib 3.0 Cookbook

How to do it...

The following are the steps needed to implement the logic:

1. Define the wxPython application:

app = wx.App()

2. Define the window where the plot and widgets are displayed:

window = wx.Frame(None, -1, "Embedding with wxPython")

3. Define and instantiate the figure, canvas, and toolbar:

fig = Figure(figsize=(6, 5), dpi=100)canvas = FigureCanvas(window, -1, fig)toolbar = NavigationToolbar2WxAgg(canvas)

4. Define the axes and data for the polar plot, and plot the polar graph:

ax = fig.add_subplot(111,projection='polar')theta = np.arange(0., 2., 1./180.)*np.piax.plot(theta, 5*np.cos(3*theta))

5. Define the callback function for the Slider widget:

def update(event):    n=n_slider.GetValue()    ax.clear() ax.plot(theta, 5*np.cos(n*theta)) ...
