<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/dojichart.min.js"></script>

Insert regions to the DojiChart container.

<div class="dojichart" id="myChart">
  <div class="region" data-name="timelabels"></div>
  <div class="region" data-name="price"></div>

Initialize the DojiChart instance with options.

var dojichart = new DojiChart.core.Chart(document.getElementById("myChart"), {
    fieldMap: {
      time: "time",
      open: "openBid",
      high: "highBid",
      low: "lowBid",
      close: "closeBid",
      volume: "volume"
    },
    crosshair: true
});

Create panels and add components to the chart based on the data-name attribute.

// Candlestick layer
var candle_layer = new DojiChart.layer.CandleLayer({});

// Price chart panel
var price_chart_panel = new DojiChart.panel.TimeValuePanel({
  primaryLayer: candle_layer,
  height: 250,
  grid: true
});

dojichart.addComponent("price", price_chart_panel);

// Moving average
var sma_layer = new DojiChart.layer.indicator.SimpleMovingAverageLayer({
  period: 50
});
price_chart_panel.addLayer(sma_layer);

// Time labels (at top of chart)
var time_labels_panel = new DojiChart.panel.TimeLabelsPanel();
dojichart.addComponent("timelabels", time_labels_panel);

// Volume
var volume_layer = new DojiChart.layer.indicator.VolumeLayer({
  barColor: "#3377FF",
  barWidth: 5
});

var volume_chart_panel = new DojiChart.panel.TimeValuePanel({
  height: 100,
  primaryLayer: volume_layer
});
dojichart.addComponent("volume", volume_chart_panel);

Load data you specify.

dojichart.loadData(raw_data, symbol, granularity, do_draw);
