在matplotlib中,可以使用TextArea和AnnotationBbox来绘制文本。 TextArea是一个用于绘制文本的对象,可以在图形中的任意位置添加文本。它可以用于标注图表中的特定点或区域,提供额外的信息。 AnnotationBbox是一个用于在图形中添加注释框的对象,可以包含文本或其他图形元素。它可以用于在图表中突出显示特定的数据点或区域。

Sometimes it is necessary to rotate a text annotation in a Matplotlib figure so that it is aligned with a line plotted on the figure Axes. Axes.annotation takes an argument, rotation, to allow a text label to be rotated, and a naive implementation might be as follows:...
Add one annotation Once you have created the dataset and plotted the scatterplot with the previous code, you can usetext()function of matplotlib to add annotation. The following parameters should be provided: x: the position to place the text in x axis ...
之前了解matplotlib模块加标签主要有matplotlib.pyplot.text()和matplotlib.pyplot.annotate()两个关键函数,后者适用范围更广,今天主要谈一下前者matplotlib.pyplot.text(),简写成plt.text() 。 准备知识 在此重点讲一下plt.text()的用法和参数设置,plt.text()函数基本语法如下 ...
