Practical Example

import matplotlib.pyplot as plt
import numpy as np

# Generate sample data
x_values = np.linspace(0, 10, 50)
y_values = np.sin(x_values)

# Create plot with customized line style and markers
plt.figure(figsize=(10, 6))
plt.plot(x_values, y_values, 
         linestyle='--',        # Dashed line
         color='steelblue',     # Line color
         marker='s',            # Square markers
         markersize=8,          # Marker size
         markerfacecolor='gold', # Marker fill color
         markeredgecolor='darkblue', # Marker edge color
         markeredgewidth=2,     # Marker edge width
         linewidth=2)           # Line width

plt.title('Customized Plot with Line Style and Markers')
plt.xlabel('X Axis')
plt.ylabel('Y Axis')
plt.grid(True, alpha=0.3)
plt.show()

Line Style Options

# Common line style patterns
line_styles = {
    '-': 'solid',
    '--': 'dashed',
    '-.': 'dash-dot',
    ':': 'dotted',
    '': 'no line',
    'None': 'no line'
}

# Usage example
plt.plot(x, y, linestyle='-.', color='crimson', linewidth=3)
