  <div class="control-section">
    <div>
      <ejs-stockchart
        id="stockchartcontainer"
        :primaryXAxis="primaryXAxis"
        :primaryYAxis="primaryYAxis"
        :title="title">
        <e-stockchart-series-collection>
          <e-stockchart-series :dataSource="seriesData" type="Candle"  volume='volume' xName='date' low='low' high='high' open='open' close='close'></e-stockchart-series>

<script>
import Vue from "vue";
import { chartData } from "./datasource.js";
import {
  StockChartPlugin, DateTime, CandleSeries, RangeTooltip, LineSeries,SplineSeries,
  HiloOpenCloseSeries, HiloSeries, RangeAreaSeries, Trendlines, EmaIndicator, RsiIndicator,BollingerBands,  TmaIndicator, MomentumIndicator, SmaIndicator, AtrIndicator, AccumulationDistributionIndicator, MacdIndicator, StochasticIndicator, Export
} from "@syncfusion/ej2-vue-charts";

Vue.use(StockChartPlugin);

export default {
  data() {
    return {
        seriesData:chartData,
        primaryXAxis: {
            valueType: "DateTime",
            majorGridLines: { color: "transparent" },
        },
        primaryYAxis: {
            lineStyle: { color: "transparent" },
            majorTickLines: { color: "transparent", width: 0 }
        },
      title: 'AAPL Stock Price'
    };
  },
  provide: {
    stockChart: [
      DateTime, RangeTooltip, LineSeries, SplineSeries, CandleSeries,     HiloOpenCloseSeries, HiloSeries, RangeAreaSeries, Trendlines, EmaIndicator, RsiIndicator,
      BollingerBands, TmaIndicator, MomentumIndicator, SmaIndicator, AtrIndicator,      AccumulationDistributionIndicator,  MacdIndicator, StochasticIndicator,Export
    ]
  }
};
</script>
<style>
#container {
   height: 350px;
 }
</style>

Note: To use this axis, we need to inject DateTimeService into the provide and set the valueType of axis to DateTime.

DateTimeCategory axis

DateTimeCategory axis in the stock chart is used to display only business days. To use DateTimeCategory axis, set the valueType of axis to DateTimeCategory.

        id="stockchartcontainer"
        :primaryXAxis="primaryXAxis"

  StockChartPlugin, DateTimeCategory, CandleSeries, RangeTooltip, LineSeries, SplineSeries, Tooltip, Crosshair,
  HiloOpenCloseSeries, HiloSeries, RangeAreaSeries, Trendlines, EmaIndicator, RsiIndicator,BollingerBands,  TmaIndicator, MomentumIndicator, SmaIndicator, AtrIndicator, AccumulationDistributionIndicator, MacdIndicator, StochasticIndicator, Export
} from "@syncfusion/ej2-vue-charts";

Vue.use(StockChartPlugin);

export default {
  data() {
    return {
        seriesData: series2,
        primaryXAxis: {
          valueType: "DateTimeCategory",
          majorGridLines: { width: 0 },
          crosshairTooltip: { enable: true }
        },
        crosshair: {
         enable: true
        },
        tooltip: { enable: true, header: 'AAPL Stock Price' }
    };
  },
  provide: {
    stockChart: [
      DateTimeCategory, RangeTooltip, LineSeries, SplineSeries, CandleSeries, Tooltip, Crosshair, HiloOpenCloseSeries, HiloSeries, RangeAreaSeries, Trendlines, EmaIndicator, RsiIndicator,
      BollingerBands, TmaIndicator, MomentumIndicator, SmaIndicator, AtrIndicator, AccumulationDistributionIndicator, MacdIndicator, StochasticIndicator, Export
    ]
  }
};
</script>
<style>
  #container {
    height: 350px;
  }
</style>

Note: To use this axis, we need to inject DateTimeCategoryService into the provide and set the valueType of axis to DateTimeCategory.

Logarithmic axis

Logarithmic axis uses logarithmic scale and it is very useful in visualizing data, when it has numerical values in both lower order of magnitude (eg: 10^-6) and higher order of magnitude (eg: 10⁶). To use Logarithmic axis, set the valueType of axis to Logarithmic.
