如何使用 python 中 matplotlib 中的相同 plt plot 并保存饼图和条形图

Question

I need to plot and save pie chart and bar graph using same plt from matplotlib in python. While using plt for both pie chart and bar graph and displaying them in html, second plot is coming as an overlapped figure of first one. Can you please suggest the method for the same?

Matplotlib isn't stateless, so basically you're always using the same plot.

First things first: spare yourself some hustle. Matplotlib is a pain to work with it directly. If you want to get nice plot fast, use Seaborn , which is just aggregator over Matplotlib . As Matplotlib isn't stateless, you need to clean things up, to avoid artifacts. I just use wrapper, which I decorate every plotting function with:

def __disposable_plot(func):
    def wrapper(*args, **kwargs):
        plt.figure(clear=True)
        func(*args, **kwargs)
        plt.close('all')

    return wrapper

If you need kickass plot, use ploty .
