当edge=无
原标题:Matplotlib markers disappear when edgecolor = none

I m试图绘制一些PCA数据目录。 我确实是一些典型的法典:

plt.plot(pca[:,0], pca[:,1],  . ,ms=3,  markerfacecolor = self.colors[k],
            markeredgecolor =  none )

我只想显示标记表面上没有提纲。 问题是,当标注器=无标记时,标记完全消失。 当我确定标记形形形形形色体时,它就象预期的那样运作。

我只是更新了最新版本的校正、 n等,以2.7。

感谢您的帮助。

在校正1.1

>> plt.plot(pca[:,0], pca[:,1],  . , ms=3, markerfacecolor=self.colors[k],
...          markeredgecolor=None)

页: 1

设置<代码>符号>符号> 符号或markervantcolor= un.colors[k](如Joe Kington所建议的)也应奏效。

引证:

x = np.array(np.random.rand(10))
y = np.array(np.random.rand(10))
c = np.arange(len(x))
plt.scatter(x,y, c=c, s=500, cmap = plt.cm.Paired, alpha = 0.5,linewidths=0)

或者,这也是一个很好的选择:

plt.scatter(x,y, c=c, s=500, cmap = plt.cm.Paired, alpha = 0.5,edgecolor= face )
