Python Copy Output: 在这个例子中,我们将正弦函数分成两部分:前半部分使用蓝色实线,后半部分使用红色虚线。注意我们在第二个plot调用中使用了x[49:]而不是x[50:],这是为了确保两段线条能够无缝连接。 4. 使用LineCollection实现更复杂的样式变化 对于更复杂的样式变化,我们可以使用Matplotlib的LineCollection类。这...

1. What is the difference between a bar plot and a histogram? A bar plot represents categorical data with bars of varying heights or lengths, while a histogram shows the distribution of numerical data. 2. How can I create a stacked bar chart in Matplotlib?
