Displaying matplotlib plot using Flask
A possible solution is to save the figure with plt.savefig and attach it to an HTML <img> tag.
from flask import Flask, render_templateimport matplotlib.pyplot as pltapp = Flask(__name__)@app.route('/plot')def plot(): left = [1, 2, 3, 4, 5] # heights of bars height = [10, 24, 36, 40, 5] # labels for bars tick_label = ['one', 'two', 'three', 'four', 'five'] # plotting a bar chart plt.bar(left, height, tick_label=tick_label, width=0.8, color=['red', 'green']) # naming the y-axis plt.ylabel('y - axis') # naming the x-axis plt.xlabel('x - axis') # plot title plt.title('My bar chart!') plt.savefig('static/images/plot.png') return render_template('plot.html', url='/static/images/plot.png')if __name__ == '__main__': app.run()Then on templates/plot.html
<img src={{url}} alt="Chart" height="auto" width="100%">
