Customization

The fill and textStyle property of the crosshairTooltip is used to customize the background color and font style of the crosshair label respectively. Color and width of the crosshair line can be customized by using the line property in the crosshair.

import { StockChart } from '@syncfusion/ej2-charts';
import { DateTime, AreaSeries, CandleSeries, HiloOpenCloseSeries, HiloSeries, LineSeries, SplineSeries } from '@syncfusion/ej2-charts';
import { AccumulationDistributionIndicator, AtrIndicator, BollingerBands, EmaIndicator, MomentumIndicator } from '@syncfusion/ej2-charts';
import { MacdIndicator, RsiIndicator, Trendlines, SmaIndicator, StochasticIndicator, Export } from '@syncfusion/ej2-charts';
import { TmaIndicator, RangeTooltip, Crosshair } from '@syncfusion/ej2-charts';
StockChart.Inject(DateTime, AreaSeries, CandleSeries, HiloOpenCloseSeries, HiloSeries, LineSeries, SplineSeries);
StockChart.Inject(AccumulationDistributionIndicator, AtrIndicator, BollingerBands, EmaIndicator, MomentumIndicator);
StockChart.Inject(MacdIndicator, RsiIndicator, SmaIndicator, StochasticIndicator);
StockChart.Inject(Trendlines, TmaIndicator, RangeTooltip, Crosshair, Export);
import { chartData } from './datasource.ts';

let stockChart: StockChart = new StockChart({
       primaryYAxis: {
            lineStyle: { color: 'transparent' },
            majorTickLines: { color: 'transparent', width: 0 },
            crosshairTooltip: {enable:true,fill: 'green'}
        },
        primaryXAxis: { majorGridLines: { color: 'transparent' },
        crosshairTooltip: {enable:true,fill: 'green'}},
        series: [
            {
                dataSource: chartData,
                type: 'Candle'
            }
        ],
       crosshair: {
            enable: true,
            line: {width: 2, color: 'green'}
        },
        title: 'AAPL Stock Price'
});
stockChart.appendTo('#element');
