How to create reusable chart functions?
Description:
When working on data analysis or visual reporting, you often need to create similar plots repeatedly — sometimes with different datasets or slight stylistic variations. Writing reusable chart functions is a best practice that ensures your code is clean, maintainable, and DRY (Don’t Repeat Yourself).
Code Explanation:
● def plot_chart(...): Defines a reusable function that takes Axes and data.
● ax.plot(...): Plots the line chart on the passed Axes.
● ax.set_title(...): Sets the title from the function argument.
● fig, ax = plt.subplots(): Creates a new Axes object.
● plot_chart(...): Calls the reusable chart function.
● plt.show(): Displays the plot.
Program:
import matplotlib.pyplot as plt
def plot_chart(ax, x, y, title):
ax.plot(x, y)
ax.set_title(title)
fig, ax = plt.subplots()
plot_chart(ax, [1, 2, 3], [3, 5, 1], "Reusable Chart Function")
plt.show()
Output:
