Add text to plot matplotlib In this section, we are going to learn about how toadd text to a plot in matplotlib. Before starting firstly, we understand what does“text”means. MY LATEST VIDEOS Text is the written words that we want to add to the plot. We can add text for textual inf...

通过plt.text()或ax.text()命令可在图形上添加文字。 Signature: ax.text(x, y, s, fontdict=None, withdash=<deprecated parameter>, **kwargs) Docstring: Add text to the axes. Add the text *s* to the axes at location *x*, *y*indata coordinates. ...

也可以不创建Figure对象而直接调用接下来的plot()进行绘图,这时matplotlib会自动创建一个Figure对象。 figsize参数指定Figure对象的宽度和高 度,单位为英寸。 此外还可以用dpi参数指定Figure对象的分辨率,即每英寸所表示的像素数, 这里使用默认值80。 因此本例中所创建的Figure对象的宽度为8*80 = 640个像素 plt.figure...
