Matplotlib 3.0 Cookbook

How to do it...

The following code block plots a sigmoid curve and text object on the graph, with the path_effects attributes:

1. Define the style to be used for all the plots in this session:

plt.style.use('seaborn-darkgrid')

2. Define the figure and figure size:

plt.subplots(figsize=(10,6))

3. Define the data for the plot:

x = np.linspace(-10, 10, 50)y = 1.0 / (1 + np.exp(-x))

4. Define the text to be printed on the plot with the desired path effects:

t = plt.text(-10., 1.15, 'Sigmoid with Path Effects', fontsize=40,              weight=50, va='center', path_effects=[PathPatchEffect(offset=(3, -3),                hatch='xxxx', facecolor='gray'),             PathPatchEffect(edgecolor='white', linewidth=1.1,              facecolor='black')])

5. Plot the sigmoid curve with the specified path effects ...
