scatter( "flipper_length_mm", "bill_length_mm", s=50, color=color, marker=marker, alpha=0.8, data=data ) That's a pretty good start, but let's make it better! Add labels with no overlap What's truely missing here are labels. It's very frustrating not knowing which item is ...
Scatter()所绘制的散列图可以指定每个 点的颜色和大小。 下面的程序演示了 scatter()的用法,效果如图4-27所示。 plt.figure(figsize=(8,4)) x = np.random.random(100) y = np.random.random(100) plt.scatter(x, y, s=x*1000, c=y, marker=(5, 1), alpha=0.8, lw=2, facecolors="none...

本文主要是Matplotlib从入门到精通系列第2篇,本文介绍了Matplotlib的历史,绘图元素的概念以及Matplotlib的多个层级,同时介绍了较好的参考文档置于博客前面,读者可以重点查看参考链接。本系列的目的是可以完整的完成Matplotlib从入门到精通。重点参考连接 Matplotlib三个层次 ...

#上式的后两个参数15.0 * array(datingLabels)和15.0 * array(datingLabels),实际上是s和c两个参数,用于设置大小和颜色,可以不同,具体如下: #ax.scatter(datingDataMat[:,0],datingDataMat[:,1],s=15.0*array(datingLabels),c=15.0*array(datingLabels)) ...
