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

The grey area you mentioned is called cursor
. Quoting the Tooltip
API docs:
If set false, no cursor will be drawn when tooltip is active.
So the answer to your question is:
<Tooltip cursor={false} />
BTW, I'm using recharts@1.7.1
