Is there a way to turn off this gray background that appears on hover for bar charts in Recharts?

有没有办法关闭重排图表中条形图悬停时显示的灰色背景？

Using version 1.4.1. Code (simplified) looks like this:

使用版本1.4.1。代码(简化)如下所示：



import React from "react"

// Recharts
import { Bar, BarChart, CartesianGrid, ResponsiveContainer, Tooltip, XAxis, YAxis } from "recharts"

import CustomTooltip from "../CustomTooltip"

const BarChart = ({ chartData, chartInfo }) => (
  <ResponsiveContainer width="99%" height={260}>
    <BarChart data={chartData}>
      <XAxis
        dataKey="label"
        type="category"
        allowDuplicatedCategory={true}
        tickLine={false}
        orientation="bottom"
      />

      <YAxis
        tickLine={false}
        orientation="left"
        axisLine={false}
      />

      <Tooltip
        isAnimationActive={false}
        separator={": "}
        content={<CustomTooltip />}
      />

      <CartesianGrid vertical={false} />

      {chartInfo.map(bar => (
        <Bar
          key={bar.dataKey}
          name={bar.name}
          dataKey={bar.dataKey}
          isAnimationActive={false}
        />
      ))}
    </BarChart>
  </ResponsiveContainer>
)

export default BarChart



I've poured over the API docs as well as looking through the source code. Doesn't seem to be a way to do it, but some of the demos have it disabled, like this one.

我已经翻阅了API文档并查看了源代码。似乎不是一种方法，但一些演示程序禁用了它，就像这个。



I tried setting up mine with custom shapes like that demo and rendering with Cell instead of Bar, but the background was still there on hover. The background color is #ccc but searching the repository with that keyword yielded no clear methods or props to try to override or hook into.

我试着用自定义形状设置我的，比如演示，用Cell而不是Bar渲染，但背景仍然悬停在那里。背景颜色是#ccc，但使用该关键字搜索存储库时，没有找到可以尝试覆盖或挂钩的明确方法或道具。

You can use the cursor prop on the <Tooltip /> to achieve what you need:

您可以使用 上的光标道具来实现所需的功能：



<Tooltip cursor={{fill: '#f00'}} />


Here's a working fiddle I made based on some example from their docs.

这是我根据他们的文档中的一些例子制作的实用小提琴。



You can simply use transparent as a value for the fill property.

您可以简单地使用透明作为Fill属性的值。





const {BarChart, Bar, XAxis, YAxis, CartesianGrid, Tooltip, Legend} = Recharts;
const data = [
      {name: 'Page A', uv: 4000, pv: 2400, amt: 2400},
      {name: 'Page B', uv: 3000, pv: 1398, amt: 2210},
      {name: 'Page C', uv: 2000, pv: 9800, amt: 2290},
      {name: 'Page D', uv: 2780, pv: 3908, amt: 2000},
      {name: 'Page E', uv: 1890, pv: 4800, amt: 2181},
      {name: 'Page F', uv: 2390, pv: 3800, amt: 2500},
      {name: 'Page G', uv: 3490, pv: 4300, amt: 2100},
];
const SimpleBarChart = React.createClass({
	render () {
  	return (
    	<BarChart width={600} height={300} data={data}
            margin={{top: 5, right: 30, left: 20, bottom: 5}}>
       <CartesianGrid strokeDasharray="3 3"/>
       <XAxis dataKey="name"/>
       <YAxis/>
       <Tooltip cursor={{fill: 'transparent'}}/>
       <Legend />
       <Bar dataKey="pv" fill="#8884d8" />
       <Bar dataKey="uv" fill="#82ca9d" />
      </BarChart>
    );
  }
})

ReactDOM.render(
  <SimpleBarChart />,
  document.getElementById('container')
);

body {
  margin: 0;
}

#container {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  padding: 10px;
  width: 800px;
  height: 800px;
  background-color: #fff;
}

<div id="container">
  <!-- This element's contents will be replaced with your component. -->
</div>





The grey area you mentioned is called cursor. Quoting the Tooltip API docs:

您提到的灰色区域称为光标。引用工具提示API文档：




If set false, no cursor will be drawn when tooltip is active.




So the answer to your question is:

因此，你的问题的答案是：



<Tooltip cursor={false} />


BTW, I'm using [email protected]

顺便说一句，我正在使用[受保护的电子邮件]



Use below cursor attribute to Tooltip.

将下面的光标属性用于工具提示。


<Tooltip cursor={{fill: 'transparent'}}/>

Amazing! I thought for sure I had tried that prior, but I guess not because I tried it just now and it worked perfectly. Thank you!

太棒了！我以为我之前肯定试过了，但我猜不是，因为我刚刚试过了，它效果很好。谢谢!

Use following code to turn off the background color <Tooltip cursor={false} />

使用以下代码关闭背景颜色<工具提示光标={False}/>

This should be in the documentation. Thank you so much.

这应该在文档中提供。非常感谢。
