annotate()函数时需要考虑2个坐标点: graph point:想要指向的点 plot point:放说明文字的点 以上两个,都以data坐标系描述 从功能上来说,text()和annotate()的本质区别是annotate可以有箭头 arrowprops = dict(facecolor='black', shrink=0.05) 1. 2. shrink:是箭头空出一些间隙,如果不设shrink那么箭头会完全连...

text()默认在数字坐标系(就是axes在的坐标系,用坐标轴的数字来表示坐标)中画, figtext()默认在图表坐标系(就是figure在图表中啦,坐标范围从0 到 1 )中画,我们可能通过trransform参数进行坐标系的转换。反正吧,matplotlib中一共有四种坐标系,并且可以转换的哦,提一下哈。
