I think this is not a bug. In Apache ECharts, series/data with the same name means intentionally set them to be the same group. For example, if you set the name to be the same for a pie series , the data with the same name share the same color and they all dispears on legend toggling. So I think disapactAction should work similarly and this is by design.

This means you set name as the key of node. Ok, I can set label {c} , and the name of node not duplicate.

I have a suggestion:

• Modify the document in image above, 数据项名称 -> 数据项名称（键值） . It is easy to misunderstand that this value is label, not a key.

Besides this, I think my question is still a bug. If I use dataName in dispatchAction function, you select nodes by name is right. But I use dataIndex in the funciton, the result should be the node with specific index is highlight, not get the node with index then get the same name nodes.

I have another similar question about the same 'name'

As follows
When there are two connect "group" line charts, I only click to close the legend of one line chart with the same name, and the legend of the other line chart is also closed;
A example ： https://codepen.io/hongdeyuan/pen/yLjXPXv
As shown in the picture：

Whether it is possible to connect only the hover event, but not the click event
Therefore, I think whether Apache ECharts can provide a "group" for each mouse event separately, so that users can control mouse events that need to be connect “group” in a more granular way;
