Overview
A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line.
Pareto Line
Represents the cumulative percentage of the total number of occurrences, total cost, or total of the particular unit of measure.
Marker
Mark data points with built-in shapes such as circles, rectangles, ellipses, vertical lines, horizontal lines, diamonds, triangles, pentagons, crosses, and pluses. In addition to these shapes, use images to make the points more attractive.
Data label
Data labels display information about data points. Add a template to display data labels with HTML elements such as images, DIV, and spans for more informative data labels. You can rotate a data label by its given angle.
Vertical chart
The JavaScript Pareto Chart can be transposed vertically to view the data in a different perspective.
Customization
Customize the color, border, marker and dash array for the pareto column and line series using built-in APIs to make it visually unique.
JavaScript Pareto Chart Code Example
Easily get started with JavaScript Pareto Chart by using a few lines of HTML and JS code, as demonstrated below. Also explore our JavaScript Pareto Chart Example that shows how to render and configure the chart.
let data = [{ x: 'Button Defect', y: 23 }, { x: 'Pocket Defect', y: 16 },
{ x: 'Collar Defect', y: 10 }, { x: 'Cuff Defect', y: 7 },
{ x: 'Sleeve Defect', y: 6 }, { x: 'Other Defect', y: 2}],
var chart = new ej.charts.Chart({
series:[{
type: 'Pareto',
dataSource: data,
xName: 'x', yName: 'y', name: 'Defect', width: 2, opacity: 0.75, columnWidth: 0.4,
paretoOptions: {
marker: { visible: true, isFilled: true, width: 7, height: 7 },
dashArray: '3,2',
width: 2
},
}],
}, '#Chart');<!DOCTYPE html>
