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",
}
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',
style: {
fontFamily: '"Roboto", sans-serif',
},
height: 312,
},

enabled: false,
},
title: {
text: null,
},
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 ${showValue ? 'value' : 'count'}`,
style: {
color: '#0E2C47',
fontWeight: '500',
fontSize: '12px',
letterSpacing: '0.3px',
lineHeight: '14.4px',
},
},
labels: {
style: {
fontSize: '8px',
color: '#808992',
},
useHTML: true,
formatter() {
// eslint-disable-next-line react/no-this-in-sfc
const collection = this.value;
const format = Math.abs(collection) > 999 ? `${Math.sign(collection) * ((Math.abs(collection) / 1000).toFixed(1))}K` : Math.sign(collection) * Math.abs(collection);
return `${format}`;
},
},
useHTML: true,
},
legend: {

I'm using echarts-for-react to create a gauge. I'm trying to disable the hover effect on the pointer.
The current behaviour is that I have a circle with a small pointer, and when hovering, the pointer covers the text. I've tried setting emphasis: null but it didn't change anything.
Here's the pictures demonstrating this issue:
Normal Behaviour
When hovering
Here's my code:
const series = {

shadowBlur: 10,
shadowOffsetX: 5,
shadowOffsetY: 5
}
},

If I change stacking to percent ,all labels are visible. minPointLength is set to make minimum column stacks width for a relatively less number
use following :
plotOptions: {
column: {
stacking: 'percent',
minPointLength:10 //this needs to added
}
}
