The chart #260 aims to describe how to perform a basic wordcloud. This page shows how to customize it. Here are a few tips. Note that each chart always starts the same way:
# Libraries
from wordcloud import WordCloud
import matplotlib.pyplot as plt
# Create a list of word

- Maximum and minimum font size
-
You can control minimum and maximum font size of your wordcloud. For example, let’s imagine you want only words written in small font:
wordcloud = WordCloud(width=480, height=480, max_font_size=20, min_font_size=10).generate(text) plt.figure() plt.imshow(wordcloud, interpolation="bilinear") plt.axis("off") plt.margins(x=0, y=0) plt.show() - Number of words
-
It is possible to set a maximum number of words to display on the tagcloud. Let’s assume I want to show only the 3 most frequent words:
wordcloud = WordCloud(width=480, height=480, max_words=3).generate(text) plt.figure() plt.imshow(wordcloud, interpolation="bilinear") plt.axis("off") plt.margins(x=0, y=0) plt.show() - Remove some words
-
You can remove some words that don’t interest you. Just list them as follow:
wordcloud = WordCloud(width=480, height=480, stopwords=["Python", "Matplotlib"]).generate(text) plt.figure() plt.imshow(wordcloud, interpolation="bilinear") plt.axis("off") plt.margins(x=0, y=0) plt.show() - Change background
-
Change the color of the background of your python wordcloud:
wordcloud = WordCloud(width=480, height=480, background_color="skyblue").generate(text) plt.figure() plt.imshow(wordcloud, interpolation="bilinear") plt.axis("off") plt.margins(x=0, y=0) plt.show() - Change color of words
-
And finally change the color of words using whatever palette!
wordcloud = WordCloud(width=480, height=480, colormap="Blues").generate(text) plt.figure() plt.imshow(wordcloud, interpolation="bilinear") plt.axis("off") plt.margins(x=0, y=0) plt.show()
