Pareto

Pareto charts are used to find the cumulative values of data in different categories. It is a combination of Column and Line series, where the initial values are represented by the column chart and the cumulative values are represented by the line chart.

To render a pareto series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

  • Set the series type: Define the series type as Pareto in your chart configuration. This indicates that the data should be represented as a pareto chart, will use a combination of column and line series.
/**
 * Sample for Pareto chart
 */

var paretoData = [
    { x: 'Button Defect', y: 23 },
    { x: 'Pocket Defect', y: 16 },
    { x: 'Coller Defect', y: 10 },
    { x: 'Cuff Defect', y: 7 },
    { x: 'Sleeve Defect', y: 6 },
    { x: 'Other Defect', y: 2 }
];

var chart = new ej.charts.Chart({
    //Initializing Primary X Axis
    primaryXAxis: {
        interval: 1,
        valueType: 'Category',
        majorGridLines: { width: 0 }, minorGridLines: { width: 0 },
        majorTickLines: { width: 0 }, minorTickLines: { width: 0 },
        lineStyle: { width: 0 }, labelIntersectAction: 'Rotate45'
    },
    //Initializing Primary Y Axis
    primaryYAxis:
    {
        title: 'Frequency of Occurence',
        minimum: 0,
        maximum: 25,
        interval: 5,
        lineStyle: { width: 0 },
        majorTickLines: { width: 0 }, majorGridLines: { width: 1 },
        minorGridLines: { width: 1 }, minorTickLines: { width: 0 }
    },
    chartArea: {
        border: {
            width: 0
        }
    },
    //Initializing Chart Series
    series: [
        {
            type: 'Pareto',
            dataSource: paretoData,
            xName: 'x', yName: 'y', name: 'Defect', width: 2,
            paretoOptions: {
                marker: { visible: true, isFilled: true, width: 7, height: 7 },

    }

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName and yName properties.

/**
 * Sample for Pareto chart
 */

var paretoData = [
    { x: 'Button Defect', y: 23 },
    { x: 'Pocket Defect', y: 16 },
    { x: 'Coller Defect', y: 10 },
    { x: 'Cuff Defect', y: 7 },
    { x: 'Sleeve Defect', y: 6 },
    { x: 'Other Defect', y: 2 }
];

var chart = new ej.charts.Chart({
    //Initializing Primary X Axis
    primaryXAxis: {
        interval: 1,
        valueType: 'Category',
        majorGridLines: { width: 0 }, minorGridLines: { width: 0 },
        majorTickLines: { width: 0 }, minorTickLines: { width: 0 },
        lineStyle: { width: 0 }, labelIntersectAction: 'Rotate45'
    },
    //Initializing Primary Y Axis
    primaryYAxis:
    {
        title: 'Frequency of Occurence',
        minimum: 0,
        maximum: 25,
        interval: 5,
        lineStyle: { width: 0 },
        majorTickLines: { width: 0 }, majorGridLines: { width: 1 },
        minorGridLines: { width: 1 }, minorTickLines: { width: 0 }
    },

            paretoOptions: {

Pareto customization

Fill

Use the fill property to apply a color to the pareto line. By default, a color based on the theme is used.

/**

 */
var paretoData = [
    { 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({
    //Initializing Primary X Axis
    primaryXAxis: {
        interval: 1,
        valueType: 'Category',
        majorGridLines: { width: 0 }, minorGridLines: { width: 0 },

Width

Use the width property to control the thickness of the line for the pareto series, which affects its visual weight on the chart.

/**

var paretoData = [
    { x: 'Button Defect', y: 23 },
    { x: 'Pocket Defect', y: 16 },

Dash array

The dashArray property determines the pattern of dashes and gaps in the pareto line series.
