在Matplotlib 中,添加标记非常直接,可以通过plot()函数的marker参数来设置。下面是一个基础的示例,展示如何在简单的线图中添加标记。 importmatplotlib.pyplotasplt x =[1,2,3,4,5]y =[2,3,5,7,11]plt.plot(x,y,marker='o',label='Data from how2matplotlib.com')plt.legend()...
In my previous post, we have seen how we can plotmultiple bar graphon a single plot. In this post, we will see how we can plot a stacked bar graph using Python’s Matplotlib library. Astacked bar graphalso known as a stacked bar chart is a graph that is used to break down and co...

A simple Python script to plot video bitrate graph using ffprobe, thus support the newest codec like HEVC, AV1 - XuebingZhao/BitratePlotter
It would be nice to be able to visualise the connections between notes as a graph. I have seen this functionality on other applications implementing that implement a Zettelkasten-style notebook and find it very helpful. Here is an exampl...
