# Sample data

line = ax.plot(x, y, color='blue', linestyle='-', marker='o', label='Data Series 1')# Customize axis labels and title
ax.set_xlabel('X-axis Label')
ax.set_ylabel('Y-axis Label')
ax.set_title('Line Plot')# Customize ticks and grid
ax.set_xticks([1,2,3,4,5])
ax.set_yticks(range(0,15,2))
ax.grid(True)# Add a legend
ax.legend()# Save Image
