Highcharts React with Typescript Event Typing - reactjs

Highcharts Event with TypeScript
I am using custom events in my Highcharts together with the React wrapper.
As an example it toggles the legend when opening and closing the full screen.
const options: Highcharts.Options = {
chart: {
events: {
fullscreenOpen: function (this: any) {
this.update({
legend: {
enabled: true,
},
});
},
fullscreenClose: function (this: any) {
this.update({
legend: {
enabled: false,
},
});
},
},
},
};
Correct typing?
How can I type the event correctly and can get rid of the this: any?

You can check types in Highcharts API. In your case it will be:
chart: {
events: {
fullscreenOpen: function (this: Highcharts.Chart) {
this.update({
legend: {
enabled: true
}
});
},
fullscreenClose: function (this: Highcharts.Chart) {
this.update({
legend: {
enabled: false
}
});
},
},
}

Adding series to highchart and remove loading without creating new chart

I'm using Highchart with React.
For the moment I created a starting options:
/**
* Initial chart options, with "loading" enabled
*/
const chartOptions = {
accessibility: {
enabled: false
},
chart: {
type: "column",
events: {
load() {
const chart = this;
chart.showLoading(`${LOADING}...`);
}
}
}
};
In that component I call an API that returns some data to use. So, at that moment, I want to remove the "loading" and adding the data.
I solved for the moment with:
const [options, setOptions] = useState(chartOptions);
useEffect(() => {
if (detail) {
setOptions({
...chartOptions,
chart: {
type: "column"
},
xAxis: {
categories: detail.map(
(item) =>
`${item.data_em.substring(4, 6)}/${item.data_em.substring(0, 4)}`
)
},
series: [
{
name: "Alfa",
color: "#69BC66",
data: detail.map((item) => item.ricevuti)
},
{
name: "Beta",
color: "#DC3545",
data: detail.map((item) => item.mancanti)
},
]
});
}
}, [detail]);
<ChartComponent options={options} />
So, setting a new options in local State when data are ready. But I imagine that in this manner I get a different chart.
It works, but is there a better method?
With using the highcharts-react-official wrapper, the chart is recreated on state update only if immutable option is enabled. Otherwise, only chart.update method is called to apply changes.
Therefore, it is better to apply only the new options. In your case it will be:
useEffect(() => {
if (detail) {
setOptions({
chart: {
type: "column"
},
xAxis: {
categories: detail.map(
(item) =>
`${item.data_em.substring(4, 6)}/${item.data_em.substring(0, 4)}`
)
},
series: [{
name: "Alfa",
color: "#69BC66",
data: detail.map((item) => item.ricevuti)
},
{
name: "Beta",
color: "#DC3545",
data: detail.map((item) => item.mancanti)
},
]
});
}
}, [detail]);

High charts / Stacked Bar - Legends Disable hover

We have implemented high chart - Stacked bar as below -
const options = {
chart: {
….
},
title: {
text: ''
},
xAxis: {
visible: false,
categories: ['']
},
credits: {
enabled: false
},
yAxis: {
visible: false,
…….
},
legend: {
itemStyle: {
cursor: 'default',
fontWeight: 'normal'
},
reversed: true
},
plotOptions: {
series: {
cursor: 'default',
stacking: 'normal',
enableMouseTracking: false,
events: {
legendItemClick: function () {
return false;
}
},
states: {
hover: {
enabled: false
}
}
}
},
tooltip: {
useHTML: true,
enabled: false,
outside: true,
followPointer: true,
crosshairs: false,
},
accessibility: {
…….
},
exporting: {
enabled: false
},
series: props.series
};
It loads fine, also hovering on any of the block does not change opacity for other blocks.
How can we disable hovering on legends below stacked bar?
Example - http://jsfiddle.net/clockworked247/FGmgC/
In above link, basically hover effect on John, Joe, Jane, Janet legends need to be disabled.
Thanks all.
Below answer helped, and worked.
Above link should help. If you are looking for more solutions you can also achieve it using CSS. Make pointer event none for legends like .highcharts-legend-item:{ pointer-events:none; }

ApexCharts don't showing toolbar

I'm using ApexCharts with React and i'm using a line's chart and it's not showing the toolbar, someone can help me?
My summed up state of options:
const [propriedades, setPropriedades] = useState({
options: {
chart: {
height: 150,
type: 'line',
selection: {
enabled: true
},
toolbar: {
tools: {
zoomin: true,
zoomout: true,
}
}
},
dataLabels: {
enabled: false
},
stroke: {
curve: 'straight'
}
},
});
xaxis: {tickPlacement: "on"},
For Angular it was solved by adding this line

MUIDataTable: In react application viewColumns options how to display the Checkbox List for column vertically

I have a MUI Table Implementation such that the options object viewColumns is set to true, which is supposed to display the popper to choose the columns to be displayed in vertical list of checkbox as shown below:
, but I am getting it horizontally as displayed in screenshot below:
The options to be passed in MUIDataTable components is defined as:
const options = {
filter: true,
filterType: "dropdown",
print: false,
viewColumns: true,
selectableRows: false,
onRowClick: (rowData) => {
console.log("RowClicked->", rowData);
},
responsive: "stacked",
fixedHeaderOptions: {
xAxis: false,
yAxis: true,
},
};
columns defines as:
export const DEAL_GRID_COLUMNS = [
{
name: "someReference",
label: "Some Reference",
options: {
filter: true,
sort: true,
},
},
{
name: "businessTeam",
label: "Business Teams",
options: {
filter: true,
sort: true,
},
},
{
name: "keyContact",
label: "Key Contact Lead",
options: {
filter: true,
sort: true,
},
},
.....
.....
.....
.....
];
and the component is consumed as
<MUIDataTable data={gridData} columns={DEAL_GRID_COLUMNS} options={options} />
here gridData is recieved from Api response
I made sample example using your options and I found viewColumns popper as vertical. I assume there is mui-datatable version issue. FYI, I am using "mui-datatables": "^2.14.0"
Here is the example:
import React, {useEffect, useState} from "react";
import MUIDataTable from "mui-datatables";
import axios from 'axios';
export default function DataTable() {
const [posts, setPost] = useState([]);
let signal = axios.CancelToken.source();
useEffect(() => {
let isSubscribed = true;
axios.get(`https://jsonplaceholder.typicode.com/posts`, {
cancelToken: signal.token,
})
.then(res => {
const posts = res.data;
setPost(posts);
}).catch(err => {
console.log(err);
});
return function cleanup() {
isSubscribed = false;
signal.cancel('Api is being canceled');
}
}, []);
const columns = ["id", "title", "body"];
const options = {
filter: true,
filterType: "dropdown",
print: false,
viewColumns: true,
selectableRows: 'none',
onRowClick: (rowData) => {
console.log("RowClicked->", rowData);
},
responsive: "stacked",
fixedHeaderOptions: {
xAxis: false,
yAxis: true,
},
};
return (
<MUIDataTable
title={"Posts"}
data={posts}
columns={columns}
options={options}
/>
);
}
You can check this output screen
I fixed this by overriding its maxWidth as
MuiPopover: {
paper: {
maxWidth: "16%",
},
}

Zoom and Pan in react-chartjs-2

I have recently implemented chart display using react-chartjs-2 (https://github.com/jerairrest/react-chartjs-2)
I want to enable zooming and panning feature so that it will be more user-friendly in touch based screens. To implement this features, I installed react-hammerjs and chartjs-plugin-zoom.
import {Chart, Line} from 'react-chartjs-2';
import Hammer from 'react-hammerjs';
import zoom from 'chartjs-plugin-zoom'
And I registered the plugin
componentWillMount(){
Chart.plugins.register(zoom)
}
And the render method goes as follows:
render(){
return <Line data={data} options={options} />
}
Pan and Zoom options:
pan:{
enabled=true,
mode:'x'
},
zoom:{
enabled:true,
drag:true,
mode:'xy'
}
I guess this is the correct method to implement. Unfortunately, the above implementation did not work. I will be really grateful if some of you guys already implemented Zooming and Panning using react-chartjs-2 plugin, please share if how you achieved these functionalities. Or you could point out the problem in my code above.
In order to add Zoom and Pan capabilities to your chart components based on react-chartjs-2, you can follow the steps as shown below:
Step 1: you need to install chartjs-plugin-zoom
$ npm install chartjs-plugin-zoom
Step 2: Import chartjs-plugin-zoom in your chart component
import 'chartjs-plugin-zoom';
Step 3: Enable zoom and pan in the ChartJS component options
zoom: {
enabled: true,
mode: 'x',
},
pan: {
enabled: true,
mode: 'x',
},
That's it. So now your chart component should look like this:
import React from 'react';
import { Line } from 'react-chartjs-2';
import 'chartjs-plugin-zoom';
export default function TimelineChart({ dailyDataSets }) {
const lineChart = dailyDataSets[0] ? (
<Line
data={{
labels: dailyDataSets.map(({ date }) => date),
datasets: [
{
data: dailyDataSets.map((data) => data.attr1),
label: 'First data set',
borderColor: 'red',
fill: true,
},
{
data: dailyDataSets.map((data) => data.attr2),
label: 'Second data set',
borderColor: 'green',
fill: true,
},
],
}}
options={{
title: { display: true, text: 'My Chart' },
zoom: {
enabled: true,
mode: 'x',
},
pan: {
enabled: true,
mode: 'x',
},
}}
/>
) : null;
return <div>{lineChart}</div>;
}
Notes:
You don't have to install hammerjs explicitly, as it will be automatically included by installing chartjs-plugin-zoom as its dependency, see below:
$ npm ls
...
├─┬ chartjs-plugin-zoom#0.7.7
│ └── hammerjs#2.0.8
...
One way to zoom as an example (at least for Mac), you can move your mouse pointer into the chart area, and then scroll your mouse down or up. Once zoomed in, you can keep your mouse clicked while dragging left or right.
There's a syntax error under pan object for enabled attribute.
You've mistakenly put = instead of :
Replace this:
pan:{
enabled=true,
...
},
With:
pan:{
enabled:true,
...
},
And also as #Jun Bin suggested:
Install hammerjs as:
npm install hammerjs --save
And in your component, import it as:
import Hammer from "hammerjs";
you imported the wrong hammer it should be from "hammerjs";
You need to add import 'chartjs-plugin-zoom'; and then add zoom options into options.plugins.zoom, like:
const options = {
plugins: {
zoom: {
pan: {
enabled: true,
mode: 'x',
},
zoom: {
enabled: true,
drag: true,
mode: 'xy'
}
}
}
};
