Change Point to Comma in Matplotlib Graphics in Python
Below are some of the ways by which we can change the point to a comma in Matplotlib graphics in Python:
- Using String Replace in Tick Labels
- Using Custom Tick Formatter
Using String Replace in Tick Labels
In this example, a simple line plot is created using Matplotlib, representing data points with purple lines. The x and y-axis tick labels are customized to replace decimal points with commas for improved readability.
import matplotlib.pyplot as plt
# Example data
x = [1, 2, 3, 4, 5]
y = [2.5, 1.5, 3.5, 2.0, 4.5]
# Plot
plt.plot(x, y, 'purple')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.title('Example Plot')
plt.grid(True)
# Replace points with commas in tick labels
plt.xticks([tick for tick in plt.xticks()[0]], [
str(tick).replace('.', ',') for tick in plt.xticks()[0]])
plt.yticks([tick for tick in plt.yticks()[0]], [
str(tick).replace('.', ',') for tick in plt.yticks()[0]])
plt.show()
Output:
Using Custom Tick Formatter
In this example, a line plot is generated using Matplotlib with gold-colored lines. The x and y-axis tick labels are formatted to replace decimal points with commas for enhanced visual presentation, achieved by defining a custom formatting function using FuncFormatter
.
import matplotlib.pyplot as plt
from matplotlib.ticker import FuncFormatter
# Example data
x = [1, 2, 3, 4, 5]
y = [2.5, 1.5, 3.5, 2.0, 4.5]
# Plot
plt.plot(x, y, 'gold')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.title('Example Plot')
plt.grid(True)
def comma_formatter(x, pos):
return str(x).replace('.', ',')
plt.gca().xaxis.set_major_formatter(FuncFormatter(comma_formatter))
plt.gca().yaxis.set_major_formatter(FuncFormatter(comma_formatter))
plt.show()
Output:
How to Change Point to Comma in Matplotlib Graphics in Python
We are given a Matplotlib Graph and our task is to change the point to a comma in Matplotlib Graphics such that there is only a comma in the whole graph instead of a point. In this article, we will see how we can change the point to comma in Matplotlib Graphics in Python.
