求教问题：echarts focusNodeAdjacency=true，鼠标hover高亮以后背景能否设置透明度

[王凯月 <wk...@163.com>]

您好，有个问题想请假一下。




问题背景：

focusNodeAdjacency属性设置为true，鼠标hover到元素上，会高亮元素，同时出现遮罩。




问题：

这个遮罩能够修改透明度？

Hi,

It's possible to change the default opacity of the blurred items when
focusing by setting the `*blur*` state option.

Here are some links for your reference:
