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



Screenshot



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



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.



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.

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



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


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



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





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;
}
