Data point customization

The color of individual data point or data points within a range can be customized using the options below.

Point color mapping

You can bind the color for the points from dataSource for the series using pointColorMapping property.

import { Chart, ColumnSeries, Category } from '@syncfusion/ej2-charts';
Chart.Inject(ColumnSeries, Category);

let chart: Chart = new Chart({
    primaryXAxis: { valueType: 'Category', majorGridLines: { width: 0 } },
        primaryYAxis: {
            lineStyle: { width: 0 },
            majorTickLines: { width: 0 },
            minorTickLines: { width: 0 },
            labelFormat: '{value}°C',
        },
        chartArea: {
            border: {
                width: 0
            }
        },
        series: [
            {
                pointColorMapping: "color",
                dataSource: [
                    { x: 'Jan', y: 6.96, color: "red" },
                    { x: 'Feb', y: 8.9, color: "blue" },
                    { x: 'Mar', y: 12, color: "orange" },

                    { x: 'May', y: 22.1, color: "grey" }

                ], xName: 'x', yName: 'y', type: 'Column',
                animation: { enable: false },
                cornerRadius: {
                    topLeft: 10, topRight: 10
                },
            }

Range color mapping

You can differentiate data points based on their y values using rangeColorSettings in the chart.

import { Chart, ColumnSeries, Category, Legend, Selection } from '@syncfusion/ej2-charts';
Chart.Inject(ColumnSeries, Category, Legend, Selection);

let chart: Chart = new Chart({
    selectionMode: 'Point',
        primaryXAxis: { valueType: 'Category', majorGridLines: { width: 0 } },
        primaryYAxis: {
            lineStyle: { width: 0 },
            majorTickLines: { width: 0 },
            minorTickLines: { width: 0 },
            labelFormat: '{value}°C',
        },
        chartArea: {
            border: {
                width: 0
            }
        },

                },
            }
        ],
        rangeColorSettings: [
            {
                label: '1°C to 10°C',
                start: 1,
                end: 10,
                colors: ['#F9D422']

        ],
        legendSettings: {
            mode: 'Range',
            toggleVisibility: false

Animation

You can customize animation for a particular series using animation property. You can enable or disable animation of the series using enable property, duration specifies the duration of an animation and delay allows us to start the animation at desire time.

import { Chart, ColumnSeries, Category, ISeriesRenderEventArgs } from '@syncfusion/ej2-charts';
Chart.Inject(ColumnSeries, Category);
let chartData: any[] = [
      { country: "USA", gold: 50 },
      { country: "China", gold: 40 },

Fluid animation

Fluid animation used to animate series with updated dataSource continues animation rather than animation whole series. You can customize animation for a particular series using [animate] method.

            labelPosition: 'Inside', labelStyle: { color: '#ffffff' }
