According to the documentation, you can Set the chart-specific events you want to listen to and the corresponding callback. The example is given uses select which works fine (I've setup an example here. The problem comes when I try to use any other chart type.
From the google charts documentation, for a bar chart, I should be able to use a click event:
When I add a click event like so:
{
eventName: "click",
callback({}) {
console.log("clicked");
}
}
Nothing happens, but the select event still works. I've setup a code sandbox here to demonstrate this behavior. This also happens for animationfinish, onmouseover, and every other event I've checked.
Looks like rakannimer already answered this in #263 on the GitHub repository, but figured I'd answer this anyway in case anyone else was having this issue.
As this stack overflow answer does a great job of explaining, the ready event must be fired before chart events (like those in the screenshot) can be triggered. Therefore, if you want to use any other event, you have to initiate them in a callback like this:
<Chart
chartType="ScatterChart"
width="80%"
height="400px"
data={data}
options={options}
legendToggle
chartEvents={[
{
eventName: "ready",
callback: ({ chartWrapper, google }) => {
const chart = chartWrapper.getChart();
google.visualization.events.addListener(chart, "onmouseover", e => {
const { row, column } = e;
console.warn("MOUSE OVER ", { row, column });
});
google.visualization.events.addListener(chart, "onmouseout", e => {
const { row, column } = e;
console.warn("MOUSE OUT ", { row, column });
});
}
}
]}
/>
Please check below code snippet for adding click event:
import * as React from "react";
import { Chart } from "react-google-charts";
const chartEvents = [
{
callback: ({ chartWrapper, google }) => {
const chart = chartWrapper.getChart();
chart.container.addEventListener("click", (ev) => console.log(ev))
},
eventName: "ready"
}
];
const data = [
["age", "weight"],
[8, 12],
[4, 5.5],
[11, 14],
[4, 5],
[3, 3.5],
[6.5, 7]
];
const options = {
title: "Age vs. Weight comparison",
hAxis: { title: "Age", viewWindow: { min: 0, max: 15 } },
vAxis: { title: "Weight", viewWindow: { min: 0, max: 15 } },
legend: "none"
};
const ExampleChart = () => {
return (
<Chart
chartType="ScatterChart"
data={data}
options={options}
graphID="ScatterChart"
width="100%"
height="400px"
chartEvents={chartEvents}
/>
);
};
export default ExampleChart;
In addition to the solution provided by #jake, the chartWrapper is no more available in the callback event. In my case, replacing it with wrapper works. Like
<Chart
chartType="ScatterChart"
width="80%"
height="400px"
data={data}
options={options}
legendToggle
chartEvents={[
{
eventName: "ready",
callback: ({ wrapper, google }) => {
const chart = wrapper.getChart();
google.visualization.events.addListener(chart, "onmouseover", e => {
const { row, column } = e;
console.warn("MOUSE OVER ", { row, column });
});
google.visualization.events.addListener(chart, "onmouseout", e => {
const { row, column } = e;
console.warn("MOUSE OUT ", { row, column });
});
}
}
]}
/>```

i want to get the value for the node which is selected by the user in graph.
I have tried with this solution but not getting the values.
const ChartEvents = [
{ eventName: "select",callback({ chartWrapper }) {console.log("Selected ", chartWrapper.getChart().getSelection());}];
<Chart chartType="TreeMap" data={data} graphID="TreeMap" options={options} width="100%" height="400px" chartEvents={ChartEvents} />
codesandbox code
you need to use the 'ready' event on the chartwrapper,
then assign the 'select' event on the chart,
as follows...
const ChartEvents = [
{
eventName: "ready",
callback: ({ chartWrapper, google }) => {
const chart = chartWrapper.getChart();
const data = chartWrapper.getDataTable();
google.visualization.events.addListener(chart, "select", function () {
var selection = chart.getSelection();
console.log("Selected ", selection);
if (selection.length > 0) {
console.log("Market trade volume (size) ", data.getValue(selection[0].row, 2));
console.log("Market increase/decrease (color) ", data.getValue(selection[0].row, 3));
}
});
}
}
];
I have nivo line chart with gaps like this:
Gaps are covered by passing y/value: null in november and december in data series
Tooltip displays only on data points and this is correct, but I want add tooltip at November and December with explanation why there is no data.
The solution is to add custom layer 'mesh' which is responsible for displaying tooltips on line chart.
You have to declare custom layers in <ResponsiveLine component:
layers={[
'grid',
'markers',
'axes',
'areas',
'crosshair',
'lines',
'slices',
'points',
CustomMesh,
'legends',
]}
Create CustomMesh component:
const CustomMesh = (layerData: any) => {
const { showTooltipAt, hideTooltip } = useTooltip();
const handleMouseEnter = (point: any) => {
showTooltipAt(
layerData.tooltip({ point }),
[point.x + layerData.margin.left, point.y + layerData.margin.top],
'top'
);
};
const handleMouseMove = (point: any) => {
showTooltipAt(
layerData.tooltip({ point }),
[point.x + layerData.margin.left, point.y + layerData.margin.top],
'top'
);
};
const handleMouseLeave = (point: any) => {
hideTooltip();
};
const nullValuePoints = layerData.series.reduce((acc: any[], cur: any) => {
cur.data.forEach(({ data, position }: any) => {
if (data.y === null) {
const point = {
x: position.x,
y: 100, //whatever you want
data: {
x: data.x,
},
};
acc.push(point);
}
});
return acc;
}, []);
return (
<Mesh
nodes={[...layerData.points, ...nullValuePoints]}
width={layerData.width}
height={layerData.height}
onMouseEnter={handleMouseEnter}
onMouseMove={handleMouseMove}
onMouseLeave={handleMouseLeave}
debug={layerData.debugMesh}
/>
);
};
When nullValuePoints are my custom points with no data
Import required packages:
import { Mesh } from '#nivo/voronoi';
import { useTooltip } from '#nivo/tooltip';
result:
I am trying to render multiple checkboxes that have two functions:
Show two states: checked and unchecked
Update a checked array with the checked checkboxes
Currently, I am successfully able to accomplish these two goals with dummy data:
const dummyPlayers = [
{ id: 1, name: 'Puppa' },
{ id: 2, name: 'Korvo' },
{ id: 3, name: 'Jesse' },
{ id: 4, name: 'Terry' },
{ id: 5, name: 'Gobblins' }
]
This is the shape of the array I want to populate the checkboxes with:
[
{
"id": "936d6050-00df-4bd4-bc54-6ce58ad0210c",
"name": "Travis",
"owner": "moralesfam",
"type": "Member",
"createdAt": "2021-09-24T20:08:02.292Z",
"updatedAt": "2021-09-24T20:08:02.292Z"
}...
]
However, when I start pulling data in from a database with Graphql, while I am able to render the checkboxes to the DOM, they are not interactive (don't show checked state) and don't log the checked checkboxes.
I bring in the data, an array of objects through a custom React hook, called useMembers and the data is stored in a members array. Console logging members prints out the array, but as soon as I swap the dummyPlayers for the members array, the two goals I stated earlier are unsuccessful.
// RecordGame.js
import React, { useState } from 'react'
import useLoadMembers from '../hooks/useLoadMembers'
import useUser from '../hooks/useUser'
function RecordGame() {
const dummyPlayers = [
{ id: 1, name: 'Puppa' },
{ id: 2, name: 'Korvo' },
{ id: 3, name: 'Jesse' },
{ id: 4, name: 'Terry' },
{ id: 5, name: 'Gobblins' },
]
const { members } = useLoadMembers(updateLoading)
const { user } = useUser()
const [checkedState, setCheckedState] = useState(
new Array(members.length).fill(false)
)
let playingPlayers = []
for (var index in checkedState) {
if (checkedState[index] === true) {
playingPlayers.push(dummyPlayers[index])
}
}
console.log(playingPlayers)
const handleOnChange = (position) => {
const updatedCheckedState = checkedState.map((player, index) =>
index === position ? !player : player
)
setCheckedState(updatedCheckedState)
}
// Rendered elements
const playerCheckboxes = dummyPlayers.map((player, index) => {
return (
<div key={index}>
<label htmlFor={player.name}>
<input
type="checkbox"
id={player.name}
name={player.name}
checked={checkedState[index]}
onChange={() => handleOnChange(index)}
/>
<span> {player.name}</span>
</label>
</div>
)
})
return (
<div>
<form>
{/* Game Players */}
<div>
<label htmlFor="players">
Who Played?
</label>
<div>{playerCheckboxes}</div>
</div>
</form>
</div>
)}
</Dashboard>
)
}
export default RecordGame
//useLoadMember.js
import { useState, useEffect } from 'react'
import { API, Auth } from 'aws-amplify'
import { listMembers } from '../graphql/queries'
const useLoadMembers = (updateLoading) => {
const [members, updateMembers] = useState([])
useEffect(() => {
fetchMembers()
// eslint-disable-next-line react-hooks/exhaustive-deps
}, [])
const fetchMembers = async () => {
try {
let memberData = await API.graphql({
query: listMembers,
variables: { limit: 100 },
})
updateLoading(false)
let allMembers = memberData.data.listMembers.items
setFilteredMembers(allMembers)
} catch (err) {
console.error(err)
}
}
const setFilteredMembers = async (allMembers) => {
const { username } = await Auth.currentAuthenticatedUser()
const myMemberData = allMembers.filter((p) => p.owner === username)
updateMembers(myMemberData)
}
return { members }
}
export default useLoadMembers
In this first, picture, I used the dummyPlayers array and got the results I wanted.
However, in this second screenshot, I replaced the dummyData with the members array and did not get any results I wanted.
I'm just confused on why I am getting different results with the same array shape.
wherever you use members you will need to check that members is not undefined before it gets used. If the api calls are not complete, it will get set initially as undefined.
eg: members && members.map(() => ....)
I am using Highcharts React wrapper in an app using Hooks, when my chart is either loaded or zoomed it fires both setExtremes and setAfterExtremes multiple times each. I've looked through for similar questions but they are related to different issues.
I've reduced the code to the minimum setup, the page is not refreshing, the data is only parsed once and added to the chart once yet, animation is disabled and it's still consistently firing both events 7 times on:
* initial population
* on zoom
Versions: react 16.9, highcharts 7.2, highcharts-react-official 2.2.2
Chart
<HighchartsReact
ref={chart1}
allowChartUpdate
highcharts={Highcharts}
options={OPTIONS1}
/>
Chart Options:
const [series1, setSeries1] = useState([]);
const OPTIONS1 = {
chart: {
type: 'spline',
zoomType: 'x',
animation: false
},
title: {
text: ''
},
xAxis: {
events: {
setExtremes: () => {
console.log('EVENT setExtremes');
},
afterSetExtremes: () => {
console.log('EVENT sfterSetExtremes');
}
},
},
plotOptions: {
series: {
animation: false
}
},
series: series1
};
Data Population:
useEffect(() => {
if (data1) {
const a = [];
_.each(data1.labels, (sLabel) => {
a.push({
name: sLabel,
data: [],
})
});
... POPULATES DATA ARRAYS...
setSeries1(a);
}
}, [data1]);
Rather the question is old I also faced the same situation. The solution is to move the chart options to a state variable. Then the event will not fire multiple times.
It is mentioned on the library docs. https://github.com/highcharts/highcharts-react -- see the "optimal way to update"
import { render } from 'react-dom';
import HighchartsReact from 'highcharts-react-official';
import Highcharts from 'highcharts';
const LineChart = () => {
const [hoverData, setHoverData] = useState(null);
// options in the state
const [chartOptions, setChartOptions] = useState({
xAxis: {
categories: ['A', 'B', 'C'],
events: {
afterSetExtremes: afterSetExtremes,
},
},
series: [
{ data: [1, 2, 3] }
],
});
function afterSetExtremes(e: Highcharts.AxisSetExtremesEventObject) {
handleDateRangeChange(e);
}
return (
<div>
<HighchartsReact
highcharts={Highcharts}
options={chartOptions}
/>
</div>
)
}
render(<LineChart />, document.getElementById('root'));```
Your useEffect is getting fired multiple times probably because you are checking for data1 and data1 is changing. have you tried putting an empty array in your useEffect and see if it is firing multiple times?
if it only fires up once then the problem is that your useEffect is checking for a value that is constantly changing
if it still fires multiple times then there is something that is triggering your useEffect
I struggled the same problem after I SetState in useEffect().
My problem was I did a (lodash) deepcopy of the Whole options.
This also create a new Event every time.
// Create options with afterSetExtremes() event
const optionsStart: Highcharts.Options = {
...
xAxis: {
events: {
afterSetExtremes: afterSetExtremesFunc,
}
},
....
// Save in state
const [chartOptions, setChartOptions] = useState(optionsStart);
// On Prop Change I update Series
// This update deepcopy whole Options. This adds one Event Every time
React.useEffect(() => {
var optionsDeepCopy = _.cloneDeep(chartOptions);
optionsDeepCopy.series?.push({
// ... Add series data
});
setChartOptions(optionsDeepCopy);
}, [xxx]);
The fix is to Only update the Series. Not whole Options.
React.useEffect(() => {
var optionsDeepCopy = _.cloneDeep(chartOptions);
optionsDeepCopy.series?.push({
// ... Add series data
});
const optionsSeries: Highcharts.Options = { series: []};
optionsSeries.series = optionsDeepCopy.series;
setChartOptions(optionsSeries);
}, [xxx]);

For anyone finding this, a few things.
Your localizer handles manipulation of dates under the hood. All dates that you pass in (from your getNow and date props, all the way to your individual event.start and event.end dates) should be true JS Date objects.
Your various method props, for working with events or setting styling or whatever, will receive true JS Date objects, not localizer objects or UTC strings or whatever.
RBC will only work with true JS Date objects. If you pass it moment instances or date strings or something else, it might display but it will operate funky, as RBC will handle all conversions under the hood, and it's use of the date-arithmatic library, internally, works with true JS Dates and not your localizer objects.
const formatted = moment(time).toDate();
I had the same issue before. The solution depends on your date field.
If date field is like start: new Date('2024-09-02T08:00:00-04:00'),
then use this: startAccessor="start"
If date field is like "start": "2024-01-15T08:00:00-04:00",
then use this: startAccessor={(event) => { return new Date(event.start) }}
In the 2nd case, below will throw same error.
startAccessor={(event) => { return moment(event.start) }}
Hope this helps.
Make sure that you have the correct values for start and end keys in your event object,
your event object should be like :
data = [
{
title: "My event",
allDay: false,
start: new Date(2020, 10, 25, 10, 0), // 10.00 AM
end: new Date(2020, 10, 25, 11, 0), // 2.00 PM
}
]
this happens when the date you are trying to display is "String" when actually "date" is an "Object" type, then you could do something like this:
as event data example convert string to date object.
{
id: 8,
title: "Meeting",
start: new Date("2022-05-12T08:00:00.000Z"),
end: new Date("2022-05-12T09:00:00.000Z")
}
