My React components pulls data for an API. The options.series.data data for the yAxis is what receives the API data.
The component is enabled to pull the data range for day/hour/minute which comes with a datestamp for when the data was recorded. How do I dynamically set the xAxis min/max range to respect the day/hour/minute duration change?
The HighchartsReact instance receives the data series via the options object that's where I'd like to setup the dynamic xAxis handler method. Perhaps it's setExtemes().
The component code is below.
import React, { Fragment, useState, useEffect } from 'react';
import { connect } from 'react-redux';
import Highcharts from 'highcharts';
import HighchartsReact from 'highcharts-react-official';
import highchartsStockChart from 'highcharts/modules/stock';
import { getDaily, getHourly, getMinute } from '../actions/getData';
import Spinner from './Spinner';
Highcharts.setOptions({
lang: {
thousandsSep: ','
}
});
highchartsStockChart(Highcharts);
const Chart = ({
match,
list: { list, loading },
getDaily,
getHourly,
getMinute,
error
}) => {
const [method, setMethod] = useState(() => getDaily);
useEffect(() => {
method(match.params.currency.toUpperCase(), 30);
}, [match.params.currency, method]);
console.log('Chart.js list:', list);
console.log('Chart.js error:', error);
console.log('Chart.js loading:', loading);
const options = {
title: {
text: 'Close Price'
},
series: [{
name: 'close price',
data: list.map(item => item.close),
tooltip: {
pointFormat: 'close price: ${point.y:,.2f}'
},
animation: false
}],
scrollbar: {
enabled: false
},
navigator: {
enabled: false
},
rangeSelector: {
inputEnabled: false,
allButtonsEnabled: true,
buttonSpacing: 10,
buttonPosition: {
align: 'left'
},
buttons: [{
type: 'day',
count: 1,
text: 'Day',
events: {
click: () => setMethod(() => getDaily)
}
}, {
type: 'hour',
count: 1,
text: 'Hour',
events: {
click: () => setMethod(() => getHourly)
}
}, {
type: 'minute',
count: 1,
text: 'Minute',
events: {
click: () => setMethod(() => getMinute)
}
}]
}
};
let content;
if (error && error.message) {
content = error.message;
} else if (!list.length || loading) {
content = <Spinner />;
} else {
content = (
<Fragment>
{list.map(item => <span key={item.time}>{item.close} </span>)}
<button onClick={() => setMethod(() => getHourly)}>set Hourly</button>
<button onClick={() => setMethod(() => getMinute)}>set Minute</button>
<HighchartsReact
highcharts={Highcharts}
options={options}
constructorType={'stockChart'}
/>
</Fragment>
);
}
return (
<div>
Chart.
{content}
</div>
);
};
const mapStateToProps = state => ({
list: state.data,
error: state.error
});
export default connect(mapStateToProps, { getDaily, getHourly, getMinute })(Chart);
You can:
use chart redraw event callback function and call setExtremes:
chart: {
events: {
redraw: function() {
if (allowChartRedraw) {
allowChartRedraw = false;
this.xAxis[0].setExtremes(0, Math.random() * 3);
}
allowChartRedraw = true;
}
}
}
Live example: http://jsfiddle.net/BlackLabel/wvpnct9h/
API Reference: https://api.highcharts.com/highcharts/chart.events.redraw
keep all of the options in a state and manipulate axis extremes by min and max properties:
componentDidMount() {
this.setState({
chartOptions: {
series: [
{
data: [Math.random() * 3, Math.random() * 3, Math.random() * 3]
}
],
xAxis: {
min: 0,
max: Math.random() * 3
}
}
});
}
Live demo: https://codesandbox.io/s/highcharts-react-demo-jo6nw
get the chart reference and call setExtremes on the xAxis.

I have a dataset that I'm passing as props to two charts:
function App() {
return (
<div>
<BarPlot data={data} />
<ScatterPlot data={data} />
</div>
);
}
In the BarPlot component I have this:
function BarPlot({ data }) {
const onBrushSelected = params => {
const selected = params.batch[0].selected;
console.log(selected[0].dataIndex);
};
const option = {
dataset: {
source: data,
},
xAxis: {},
yAxis: { type: 'category' },
series: [
{
type: 'bar',
encode: {
x: 'amount',
y: 'product',
},
},
],
toolbox: {
show: true,
},
brush: {
toolbox: ['rect', 'clear'],
throttleType: 'debounce',
throttleDelay: 300,
},
};
const onEvents = {
brushselected: onBrushSelected,
};
return (
<ReactEChartsCore echarts={echarts} option={option} onEvents={onEvents} />
);
}
How do I filter the data passed to both chart components based on brush selection in one of the charts?
I'm only able to console.log the selection here:
const onBrushSelected = params => {
const selected = params.batch[0].selected;
console.log(selected[0].dataIndex);
};
I am getting data from my database to display it on the graph. Currently, I will have to refresh the page for the graph to update. I would like to refresh the graph in x interval as my data will be inserted at x interval. Am using ant design for the graph plotting. I am using a 'home' to display my graph and another class for my data fetching.
Home.js
export class Home extends Component {
static displayName = Home.name;
render () {
return (
<div>
<h1>Dashboard</h1>
<h2>
<div className="site-card-wrapper">
Graph1
<Graph />}
</div>
</h2>
</div>
);
}
}
Temp.js
const TempGraph = () => {
const [data, setData] = useState([]);
useEffect(() => {
asyncFetch();
}, []);
const asyncFetch = () => {
fetch('link')
.then((response) => response.json())
.then((json) => setDatajson))
.catch((error) => {
console.log('fetch data failed', error);
});
};
const config = {
data,
xField: 'time',
yField: 'value',
seriesField:'location',
xAxis: {
title: {
text: 'Hours',
}
},
yAxis:{
title:{
text: 'Temperature in °',
}
},
meta: {
time: {
alias: 'hours',
},
value: {
alias: 'temperature',
max: 50,
},
},
};
return <Line {...config} />;
}
export default TempGraph;
You could just add a setInterval in your useEffect to grab the data and update them again. Don't forgot to clear the interval on return:
useEffect(() => {
const interval = setInterval(() => asyncFetch(), 5000)
return () => clearInterval(interval)
}, []}
This example triggers every 5000ms, change the value according to your needs.
I'm using REACT-PLOTLY.JS to create a scatter graph. I've got everything working apart from the graph redrawing it self every-time I change a data point when using a list of objects in the array data prop. BUT... when I manually write the array and it's containing objects, my graph does not re-draw when I change a data point, which is how it should work. The 2nd solution is not dynamic and is unusable. Can anyone help please?
re-draws graph when data point changes.
<Plot
data={plotlyData}
does not re-draw graph when data point is changed but is not dynamic and therefore unusable.
<Plot
data={[plotlyData[0],plotlyData[1]]}
I'm using functional components.
How plotData is generated. I'm using an API to get the coordinates for the X and Y axis.
import { React, useState } from "react";
import Plot from "react-plotly.js";
import { useQuery } from "react-query";
import axios from "axios";
const PlotlyGraph = (props) => {
const [plot, setPlot] = useState([]);///not in use
const { datasets } = props;
const QueryUuid = datasets.map((d) => {
// console.log("Individual Dataset:", d);
return `${d.age}-${d.kmax}-${d.frontK}-${d.pachymetry}`;
});
const { error, isLoading, data } = useQuery(
`data-${QueryUuid.join("-")}`,
() =>
axios.post("/api/calculate_cxl", {
age_baseline: datasets.map((d) => d.age),
kmax: datasets.map((d) => d.kmax),
front_k1: datasets.map((d) => d.frontK),
tpt2: datasets.map((d) => d.pachymetry),
color: datasets.map((d) => d.color),
})
);
let plotlyData;
if (error !== null || isLoading === true) {
plotlyData = [];
} else {
plotlyData = data.data.map((d, i) => {
return {
x: d.x,
y: d.y,
type: "scatter",
mode: "lines",
marker: { color: datasets[i].color },
line: {
width: 3,
},
name: `Patient ${i + 1}`,
showlegend: true,
};
});
}
console.log("plot:", plotlyData);
//- Graph Configuration
const config = {
editable: false,
scrollZoom: true,
displayModeBar: true,
displaylogo: false,
};
return (
<>
<Plot
data={plotlyData}
layout={{
yaxis: { range: [0, 1] },
xaxis: { range: [0, 5] },
autoSize: "true",
title: "Patient Comparison",
}}
style={{ width: "100%", height: " 700px" }}
useResizeHandler={true}
config={config}
revision={0}
// onInitialized={plot}
// onUpdate={(plot) => setPlot(plotlyData)}
/>
</>
);
};
export default PlotlyGraph;
I had a similar issue and was able to figure out how to dynamically update my plot with new data after every API fetch (see State Management). Since I don't have access to the API you are using, I've included my own example.
From my API, I fetch an object that looks like this:
{
28AD7D49F6E13C0A: [69.36, 64.11, 68.69, 62.1, ...],
28DDC649F6003C1C: [69.59, 63.18, 60.63, 63.08, ...],
Time: ['20:50:15', '20:50:17', '20:50:19', '20:50:21', ...]
}
Every two seconds, that objects gets updated with a new item in each array. When the state data gets updated with setData, the state object gets updated, which then causes the plot to render with new data.
Full example:
import React, { useState, useEffect } from "react";
import Plot from "react-plotly.js";
function TemperatureGraph() {
const [data, setData] = useState({});
const state = {
data: [
{
x: data["Time"],
y: data["28AD7D49F6E13C0A"],
name: "28AD7D49F6E13C0A",
type: "scatter",
mode: "lines+markers",
marker: {
color: "red",
},
},
{
x: data["Time"],
y: data["28DDC649F6003C1C"],
name: "28DDC649F6003C1C",
type: "scatter",
mode: "lines+markers",
marker: {
color: "black",
},
},
],
layout: {
width: 800,
height: 500,
title: "",
xaxis: {
title: "Time",
},
yaxis: {
title: "Temperature (F)",
},
},
frames: [],
config: {},
};
useEffect(() => {
const timer = setInterval(() => {
fetch("/get-temperatures")
.then((response) => response.json())
.then((data) => setData(data));
}, 2000);
return () => clearInterval(timer);
}, []);
return (
<div>
<Plot data={state.data} layout={state.layout} />
</div>
);
}
export default TemperatureGraph;
I'm using Zustand to store state, everything is working fine apart from this. When i click on the Song Buttons i want that to filter from the list.
Currently on fresh load it displays 3 songs. When clicking the button it should filter (and it does for first instance) but as soon as i click another button to filter again then nothing happens.
So if i chose / click Song 1 and Song 2 it should only show these songs.
I think the logic i wrote for that is correct but i must be doing something wrong with re-rendering.
Sorry i know people like to upload example here but i always find it hard with React files, so for this case I'm using https://codesandbox.io/s/damp-waterfall-e63mn?file=/src/App.js
Full code:
import { useEffect, useState } from 'react'
import create from 'zustand'
import { albums } from './albums'
export default function Home() {
const {
getFetchedData,
setFetchedData,
getAttrData,
setAttrData,
getAlbumData,
getButtonFilter,
setButtonFilter,
setAlbumData,
testState,
} = stateFetchData()
useEffect(() => {
if (getFetchedData) setAttrData(getFetchedData.feed.entry)
}, [getFetchedData, setAttrData])
useEffect(() => {
setAlbumData(getButtonFilter)
}, [getButtonFilter, setAlbumData])
// useEffect(() => {
// console.log('testState', testState)
// console.log('getAlbumData', getAlbumData)
// }, [getAlbumData, testState])
useEffect(() => {
setFetchedData()
}, [setFetchedData])
return (
<div>
<div>Filter to Show: {JSON.stringify(getButtonFilter)}</div>
<div>
{getAttrData.map((props, idx) => {
return (
<FilterButton
key={idx}
attr={props}
getDataProp={getButtonFilter}
setDataProp={setButtonFilter}
/>
)
})}
</div>
<div>
{getAlbumData?.feed?.entry?.map((props, idx) => {
return (
<div key={idx}>
<h1>{props.title.label}</h1>
</div>
)
})}
</div>
</div>
)
}
const FilterButton = ({ attr, getDataProp, setDataProp }) => {
const [filter, setFilter] = useState(false)
const filterAlbums = async (e) => {
const currentTarget = e.currentTarget.innerHTML
setFilter(!filter)
if (!filter) setDataProp([...getDataProp, currentTarget])
else setDataProp(getDataProp.filter((str) => str !== currentTarget))
}
return <button onClick={filterAlbums}>{attr.album}</button>
}
const stateFetchData = create((set) => ({
getFetchedData: albums,
setFetchedData: async () => {
set((state) => ({ ...state, getAlbumData: state.getFetchedData }))
},
getAttrData: [],
setAttrData: (data) => {
const tempArr = []
for (const iterator of data) {
tempArr.push({ album: iterator.category.attributes.label, status: false })
}
set((state) => ({ ...state, getAttrData: tempArr }))
},
getButtonFilter: [],
setButtonFilter: (data) => set((state) => ({ ...state, getButtonFilter: data })),
testState: {
feed: { entry: [] },
},
getAlbumData: [],
setAlbumData: (data) => {
set((state) => {
console.log('🚀 ~ file: index.js ~ line 107 ~ state', state)
const filter = state.getAlbumData.feed?.entry.filter((item) =>
data.includes(item.category.attributes.label),
)
return {
...state,
getAlbumData: {
...state.getAlbumData,
feed: {
...state.getAlbumData.feed,
entry: filter,
},
},
}
})
},
}))
Sample data:
export const albums = {
feed: {
entry: [
{ title: { label: 'Song 1' }, category: { attributes: { label: 'Song 1' } } },
{ title: { label: 'Song 2' }, category: { attributes: { label: 'Song 2' } } },
{ title: { label: 'Song 3' }, category: { attributes: { label: 'Song 3' } } },
],
},
}
I want to search with all the pagination and sorter field on place.
That is i want to call handleChange with searchkeyword.
So how can i call handleSearch and than call handleChange from within handleSearch?
import React from "react";
import { withRouter } from "react-router-dom";
import { Table, Button, Icon, Row, Col, Input } from "antd";
import axios from "axios";

pagination: {}
};
componentDidMount() {
this.fetch();
}
handleTableChange = (pagination, filter, sorter, value) => {
console.log(pagination, value, sorter, "Table Change");
let sorterOrder = "";
let sorterField = "";
let searchVal = "";
const pager = { ...this.state.pagination };
pager.current = pagination.current;
this.setState({
pagination: pager
});
if (value) {
console.log("inside if");
searchVal = undefined;
} else {
console.log("inside else");
searchVal = value;
}
if (sorter) {

}
if (sorter.order === "descend") {
sorterOrder = "DESC";
}
sorterField = sorter.field;
}
this.fetch({
page: pagination.current,
sortField: sorterField,

...filter,
value: searchVal
});
};
fetch = (params = {}) => {
this.setState({ loading: true });
axios.post("***/****", params).then(res => {
const pagination = { ...this.state.pagination };
let apiData = res.data.result;
if (res.data.status === 1) {
const objects = apiData.map(row => ({
key: row.id,
id: row.id,
firstName: row.firstName,
lastName: row.lastName,

}));
console.log(res.data);
pagination.total = res.data.count;
this.setState({
loading: false,
data: objects,
pagination
});
} else {
console.log("Database status is not 1!");
}
});
};
handleSearch = value => {
console.log("value", value);
this.setState({
searchValue: value
});
let searchkey = this.state.searchValue;
const pagination = { ...this.state.pagination };
const sorter = { ...this.state.sorter };
console.log("search", value, pagination, sorter);
this.handleTableChange({
value
});
};
render() {

return (
<div>
<Search
placeholder="input search text"

onSearch={value => this.handleSearch(value)}
/>
<Button
className="addBut"
style={{ marginTop: "0" }}
type="primary"
onClick={() => this.openForm()}
>
+ Add Admin
</Button>
</div>
<Table
bordered
columns={columns}
dataSource={this.state.data}
pagination={{ total: this.state.pagination.total, pageSize: 4 }}
loading={this.state.loading}
onChange={this.handleTableChange}
/>
);
}
}
export default withRouter(App);
here when i give value in search field it will call post request with request payload as follows:
{sortField: "", sortOrder: ""}
sortField: ""
sortOrder: ""
So how can i do that?
I'm not sure what you trying of achieve it here.
But you can always filter the source data of the table. Like following
<Table
bordered
columns={columns}
dataSource={this.state.data.filter(data=> Object.keys(data).filter(key => data[key].includes(searchValue)).length > 0 ? true: false)}
pagination={{ total: this.state.pagination.total, pageSize: 4 }}
loading={this.state.loading}
onChange={this.handleTableChange}
/>
let me know if it helps.
