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:

  1. 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.

  2. Inject the necessary modules: inject ParetoSeries ColumnSeries and LineSeries module. This step is essential, as it ensures that the necessary functionalities for rendering pareto series are available in your chart.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, ParetoSeries, ColumnSeries, LineSeries, Legend, Category, Tooltip, DataLabel } from '@syncfusion/ej2-react-charts';
import { chartData } from './datasource';
function App() {
    const primaryxAxis = { title: 'Defects', valueType: 'Category' };
    const primaryyAxis = { title: 'Frequency', minimum: 0, maximum: 150, interval: 30 };
    const tooltipsettings = { enable: true };
    const marker = { visible: true, width: 10, height: 10 };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} tooltip={tooltipsettings} title='Defect vs Frequency'>
                    <Inject services={[ColumnSeries, LineSeries, ParetoSeries, Legend, Tooltip, Category, DataLabel]}/>
                    <SeriesCollectionDirective>
                    <SeriesDirective dataSource={chartData} xName='x' yName='y' name='Defect' type='Pareto' marker={marker}>

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.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, ParetoSeries, ColumnSeries, LineSeries, Legend, Category, Tooltip, DataLabel } from '@syncfusion/ej2-react-charts';
import { chartData } from './datasource';
function App() {
    const primaryxAxis = { title: 'Defects', valueType: 'Category' };
    const primaryyAxis = { title: 'Frequency', minimum: 0, maximum: 150, interval: 30 };
    const tooltipsettings = { enable: true };
    const marker = { visible: true, width: 10, height: 10 };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} tooltip={tooltipsettings} title='Defect vs Frequency'>
                    <Inject services={[ColumnSeries, LineSeries, ParetoSeries, Legend, Tooltip, Category, DataLabel]}/>
                    <SeriesCollectionDirective>
                    <SeriesDirective dataSource={chartData} xName='x' yName='y' name='Defect' type='Pareto' marker={marker}>
                        </SeriesDirective>
                    </SeriesCollectionDirective>
              </ChartComponent>;

    const primaryxAxis: AxisModel= {  title: 'Defects', valueType: 'Category' }  ;
    const primaryyAxis: AxisModel= {   title: 'Frequency', minimum: 0, maximum: 150,interval: 30 }  ;
    const tooltipsettings: TooltipSettingsModel={ enable: true };
    const marker={ visible: true, width: 10, height: 10};

                        marker={ marker }>
                        </SeriesDirective>

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.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, ParetoSeries, ColumnSeries, LineSeries, Legend, Category, Tooltip, DataLabel } from '@syncfusion/ej2-react-charts';

    const primaryxAxis = { title: 'Defects', valueType: 'Category' };
    const primaryyAxis = { title: 'Frequency', minimum: 0, maximum: 150, interval: 30 };
    const tooltipsettings = { enable: true };
    const marker = { visible: true, width: 10, height: 10 };
    const paretoOptions = {
        fill: 'red'
      }
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} tooltip={tooltipsettings} title='Defect vs Frequency'>

    const marker={ visible: true, width: 10, height: 10};
    const paretoOptions: object = {
        fill: 'red'
      };

    { x: 'Sleeve Defect',  y: 6 }, 
    { x: 'Other Defect',   y: 2 }
];

Width

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

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, ParetoSeries, ColumnSeries, LineSeries, Legend, Category, Tooltip, DataLabel } from '@syncfusion/ej2-react-charts';

    const primaryyAxis = { title: 'Frequency', minimum: 0, maximum: 150, interval: 30 };
    const tooltipsettings = { enable: true };
    const marker = { visible: true, width: 10, height: 10 };
    const paretoOptions = {
      width: 4
      }
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} tooltip={tooltipsettings} title='Defect vs Frequency'>

    { x: 'Sleeve Defect',  y: 6 }, 
    { x: 'Other Defect',   y: 2 }
];

Dash array

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

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, ParetoSeries, ColumnSeries, LineSeries, Legend, Category, Tooltip, DataLabel } from '@syncfusion/ej2-react-charts';

Marker

Use the marker property to display and customize markers for individual points in a pareto line.
