Vue ChartsFinancial Charts - Configuration

Learn how to create Financial Charts with minimal configuration and customisations.

Default Configuration

Financial Charts come pre-configured with built-in features – just add your data to produce the chart shown above.

import { createApp } from 'vue';

import 'ag-charts-enterprise';
import { AgFinancialCharts } from 'ag-charts-vue3';

const ChartExample = {
    template: `
    <ag-financial-charts
      :options="options"
    />
  `,
    components: {
        'ag-financial-charts': AgFinancialCharts,
    },
    data() {
        return {
            options: {
                data: getData(),
            },
        };
    },
};

createApp(ChartExample).mount('#app');

For custom data keys, map your data properties to the appropriate AgFinancialChartOptions keys:

• dateKey : key for the date values.
• openKey: key for the open values.
• highKey: key for the high values.
• lowKey: key for the low values.
• closeKey: key for the close values.
• volumeKey: key for the volume values (optional).

Customisation

Chart Features

Financial Chart features can be enabled or disabled via the following properties:

const options: AgFinancialChartOptions = {
  // ...
  navigator: false, // disabled by default
  toolbar: true,
  rangeButtons: true,
  volume: true,
  statusBar: true,
  zoom: true,
};

In this configuration:

• navigator: Enables the mini chart navigator for easy dataset navigation.
• toolbar: Shows the Toolbar.
• rangeButtons: Provides range buttons for navigating different time periods.
• volume: Displays volume data on the chart.
• statusBar: Shows a status bar at the top of the chart when hovering over the chart series.
• zoom: Enables zoom functionality for detailed analysis of the data.

Chart Types

End users can use the Chart Type Selection Tool to choose a series type for visualising the data. However, this can also be done programmatically.

The default chart type is candlestick. To use a different chart type, set the chartType property.

const options: AgFinancialChartOptions = {
  // ...
  chartType: 'line', // Set to line
};

The chart type state can be saved, restored and programmatically initialised and modified, using the Chart State API.

The following chart types are supported:

• candlestick, hollow-candlestick, ohlc, line, step-line, hlc, high-low.

Chart Styling

Use the theme property in AgFinancialChartOptions to customise chart styles.

const options: AgFinancialChartOptions = {
  // ...
  theme: {
    palette: {
      up: { fill: "#F3A93C", stroke: "#A8492D" },
      down: { fill: "#1A00F4", stroke: "#75FBFD" }
    },
  },
};

In this configuration:

• palette: Specifies custom colours.
  • up: Colours for "rising values"
  • down: Colours for "falling values"

For additional customisation, use Theme Override Options in the theme option.
