How to correctly display large amount of data on ReactApexChart , Bar Chart. At image below, I am passing 552 entries. When amount of entries under 50 everything displays just fine, above this number starts look like a hell and performance is getting low. I am using React Js Class Component.
this.state = {
series: [{
name: props.name,
data: props.chartValue,
}, ],
options: {
grid: {
row: {
colors: ["#D6EAF8 ", "#D6EAF8"],
},
},
chart: {
type: "bar",
height: 350,
},
plotOptions: {
bar: {
borderRadius: 4,
horizontal: true,
colors: {
ranges: [{
from: 0,
to: Number.MAX_VALUE,
color: "#29ABE2",
}, ],
backgroundBarColors: [],
backgroundBarOpacity: 1,
backgroundBarRadius: 0,
},
},
},
dataLabels: {
enabled: true,
formatter: function(val) {
return val + ` min`;
},
offsetX: 15,
style: {
fontSize: "12px",
colors: ["#FFFFFF"],
},
},
xaxis: {
categories: props.ids,
labels: {
style: {
colors: [],
fontSize: "15px",
fontWeight: 500,
},
},
},
yaxis: {
categories: props.differenceInTime,
labels: {
style: {
colors: [],
fontSize: "15px",
fontWeight: 500,
},
},
axisTicks: {
show: true,
borderType: "solid",
color: "#78909C",
width: 10,
offsetX: 0,
offsetY: 0,
},
},
},
};
<div id="chart">
<ReactApexChart options={this.state.options} series={this.state.series} type="bar" />
</div>
Here is 552 entries
why put max integer for the colors? That could be a performance issue
ranges: [{
from: 0,
to: Number.MAX_VALUE,
color: "#29ABE2",
}

I create some chart in dashboard using react-chart-js.
exmaple
but I have problem now chart not clear. I decided do change chart canvas size move mouse point over the chart . but i can't find solution for that.
i currently use "react-chartjs-2": "3.3.0" and "chart.js": "^3.6.0" packages
i use this option list for draw charts
const options = {
responsive: true,

Any one can suggest solution for it.
I am using React Apex-Charts to build a horizontal Bar Chart which currently looks like this:
I want to change the default sort order to be descending not Ascending such that the bar with the highest value is at the top while the smallest value is at the bottom. How do I accomplish this?
The following is my current code:
<Chart
type='bar'
height={550}
series= {[{
name: "Transaction",
data: [4000, 4300, 4408, 4700, 5400, 5800, 6900, 11000, 12000, 13800],
}]}
options={{
title:{ text:"Top 10 Schools By Transactions", style: { fontSize: 25 , fontFamily: "IBM Plex Sans", fontWeight:700}, },
colors: ["#295fab"],
yaxis: {
labels: {
formatter: (val) => {
return `${val}`;
},
style: {fontWeight:500, fontSize: "15", colors: ["#000"], fontFamily:"IBM Plex Sans", },
},
},
xaxis: {
categories: ["Jomo Kenyatta Univerity", "Technical Univaersity of Kenya", "University of Nairobi", "Kenyatta University", "Moi University", "Masinde Muliro University", "Maasai Mara University", "Maseno University", "Laikipia University",
],
labels:{
formatter: (val) => {
return `$${val}`;
},
style: {fontSize: "14",fontWeight:500, colors: ["#000"], fontFamily:"IBM Plex Sans" },
}
},
noData: {
text: "Loading...",
},
chart: {
fontFamily: 'IBM Plex Sans',
toolbar: {
tools: {
download: true,
selection: false,
zoom: false,
zoomin: false,
zoomout: false,
pan: false,
reset: false | '<img src="/static/icons/reset.png" width="20">',
customIcons: []
},
},
},
dataLabels: {
enabled: true,
formatter: function (val) {
return `$${val}`;
},
offsetX: 40,
style: {
fontSize: '12px',
colors: ["#304758"],
}
},
plotOptions: {
bar: {
borderRadius: 16,
horizontal: true,
dataLabels: {
position: 'top', // top, center, bottom
},
}
},
legend:{
fontSize: "16px",
fontFamily: "IBM Plex Sans"
}
}}

</Chart>
Chart.js doughnut text visibility. Tell me how to make it so that when the values intersect, the text comes out and changes its position.
const myChart = new Chart(canvas,
{
type: 'doughnut',
data: {
labels: dataNameDB,
datasets: [{
data: dataCountDB,
backgroundColor: backgroundColor,
borderWidth: 0,
}],
},
plugins: [ChartDataLabels, DoughnutLabel],
options: {
cutout: 340,
responsive: true,
animation: false,
plugins: {
legend: {
display: false,
},
datalabels: {
formatter: (val, ctx) => {
return Math.round((ctx.chart.data.datasets[0].data[ctx.dataIndex] * 100) / summChart()) + "%";
},
display: (val,ctx) =>{
return 'auto';
},
clamp: true,
clip: true,
anchor: 'center',
align: 'center',
offset: 1,
font: {
size: 65,
weight: 'bold',
color: '000000'
},
color: '000000',
labels: {
value: {
color: '#000000'
}
}
},
doughnutlabel: {
labels: [{
text: summChart,
font: {
size: 140,
weight: 'bold',
color: '000000'
}
}]
}
}
}
},
);
Now it outputs something like this, but I need it to be like this:
Although the documentation says that display 'auto' is responsible for this, how to catch it when the text is hidden in order to move it?
I'm trying to customise my chart's legend. My current legend needs to look like this legend.
Basically I need to make the circular icons rectangular and change the legend text color to correspond with the icon.
I've looked everywhere in the docs but I'm not finding a solution. This is how I configured the graph below (legend > itemStyle):
useEffect(() => {
Highcharts.chart(chart.current, {
chart: {
type: 'column',

},

xAxis: {
categories,
labels: {
step: 1,
style: {
fontSize: '8px',
color: '#808992',
},
useHTML: true,
formatter() {
const day = this.value.format('D');
if (moment().isSame(this.value, 'd')) {
return `<strong style="font-weight: 900; color: #0E2C47;">${day}</strong>`;
}
return day;
},
},
gridLineWidth: 1,
},
yAxis: {
min: 0,
title: {
text: `Collections ${showValue ? 'value' : 'count'}`,
style: {
color: '#0E2C47',

fontSize: '12px',
letterSpacing: '0.3px',
lineHeight: '14.4px',
},
},

fontSize: '8px',
color: '#808992',
},
useHTML: true,
formatter() {
// eslint-disable-next-line react/no-this-in-sfc
const collection = this.value;
const format = Math.abs(collection) > 999 ? `${Math.sign(collection) * ((Math.abs(collection) / 1000).toFixed(1))}K` : Math.sign(collection) * Math.abs(collection);
return `${format}`;
},
},
useHTML: true,
},

},
},
series: [{

data: chartData.draft, // [...times(() => null, 30), ...times(random, 31)],

legendIndex: 0,
}, {

data: chartData.approved,
color: collectionStateColors.approved, // orange
legendIndex: 1,
}, {

data: chartData.expired,

legendIndex: 2,
}, {

data: chartData.submitted,
color: collectionStateColors.submitted, // purple

});
});
I have the following bar chart configuration.
const series = [
{
name: 'Net Profit',
data: [18, 34, 55, 57, 80, 70],
},
];
const options = {
chart: {
type: 'bar',
height: '50px',
toolbar: {
show: false,
},
},
grid: {
show: false,
padding: {
top: 0,
bottom: 0,
},
xaxis: {
lines: {
show: false,
},
},
yaxis: {
lines: {
show: false,
},
},
},
plotOptions: {
bar: {
horizontal: false,
columnWidth: '80%',
barHeight: '100%',
},
},
dataLabels: {
enabled: false,
},
stroke: {
show: false,
width: 0,
colors: ['transparent'],
},
fill: {
opacity: 1,
colors: [
'#000000',
'#B32824',
'#1A73E8',
'#B32824',
'#1A73E8',
'#B32824',
],
type: 'solid',
},
tooltip: {
enabled: false,
},
xaxis: {
axisTicks: {
show: false,
},
axisBorder: {
show: false,
},
labels: {
show: false,
},
},
yaxis: {
axisTicks: {
show: false,
},
axisBorder: {
show: false,
},
labels: {
show: false,
},
},
};
I am getting extra padding at the bottom as below. how can I remove that?
If you don't want to show x-axis and y-axis in your chart, you can simply do
const options = {
chart: {
type: 'bar',
height: '250px',
sparkline: {
enabled: true
}
},
}
The sparkline option will remove all paddings/margins around the chart.
I was facing the same issue, and after reading the doc I found that you should set the value of parentHeightOffset as 0, something like this
var opt1 = {
chart: {
type: 'line',
height: 200,
...
parentHeightOffset: 0,
...
},
...
};
