Steps to Reproduce

准备绘制三万个左右的散点，需要实现点击散点时显示label，但是发现部分散点点击后label无法正常显示，同时发现无法正常显示label的点在鼠标悬浮时鼠标的样式未变化。正常能标记的点鼠标悬浮时鼠标样式默认会变为手型。另外进行区域放大操作后无法正常标记的散点也可以正常标记。

large: true,
label: {
    show : false,
    position: 'outside',
    formatter:function (params) {
        if(params.value[0]){ 
            return params.value[0]
        }else{
            return ""
        }
    }
},
selectedMode: "multiple",
select: {
    label: {
         show: true
    }
}

Current Behavior

创建了多数据集多series的散点图，部分series中所有散点可能无法正常显示label

Expected Behavior

正常点击所有的散点都可以触发点击事件，标记散点名称

Environment

- OS:Windows10
- Browser:Chrome 122.0.6261.128
- Framework:Vue@3

**TITLE** [Bug] When drawing a graph of about 30,000 scatters, the style of the mouse does not change when hovering over some of the scatters, and some of them change normally

三万个节点数据，渲染不卡顿吗？请问下你是怎么做到不卡顿的

Ovilia commented 5 months ago

With large: true, scatters don't respond to mouse hover events when data number exceeds largeThreshold. This is necessary for performance consideration.

感谢您的指导，通过调高largeThreshold后，所有点都可以正常响应hover事件，即鼠标悬浮时鼠标样式默认会改变为手型。但是select散点时，label都无法正常显示。偶然发现将鼠标移入工具栏区域能够使散点的label正常显示，不知道是什么问题导致的？有什么解决办法吗？
