Quick Overview

The tradingview/charting-library-examples repository provides a collection of examples and sample code for integrating the TradingView Charting Library into various web applications. The Charting Library is a powerful and customizable charting solution for financial data visualization.

Pros

  • Comprehensive Examples: The repository offers a wide range of examples covering different use cases and integration scenarios, making it easier for developers to get started with the Charting Library.
  • Active Maintenance: The repository is actively maintained by the TradingView team, ensuring that the examples stay up-to-date with the latest library updates.
  • Detailed Documentation: The examples are accompanied by detailed documentation, providing clear instructions and explanations for each use case.
  • Community Support: The TradingView community is active and responsive, providing support and assistance to developers working with the Charting Library.

Cons

  • Specific to TradingView Charting Library: The examples are tailored to the TradingView Charting Library, which may limit their applicability to other charting solutions.
  • Potential Learning Curve: Developers new to the Charting Library may need to invest time in understanding the library's API and features before effectively utilizing the examples.
  • Limited Customization: While the examples provide a good starting point, developers may need to invest additional effort to customize the examples to fit their specific requirements.
  • Dependency on TradingView: The project is dependent on the TradingView Charting Library, which may introduce potential vendor lock-in concerns for some users.

Code Examples

Here are a few code examples from the tradingview/charting-library-examples repository:

  1. Basic Chart Integration:
// Initialize the Charting Library
const widget = window.TradingView.onready(function() {
  const widgetOptions = {
    symbol: 'AAPL',
    interval: 'D',
    container: 'tv-chart-container',
    library_path: 'charting_library/',
    locale: 'en',
    disabled_features: ['use_localstorage_for_settings'],
    enabled_features: ['study_templates'],
    charts_storage_url: 'https://saveload.tradingview.com',
    charts_storage_api_version: '1.1',
    client_id: 'tradingview.com',
    user_id: 'public_user_id',
  };

  const tvWidget = new window.TradingView.widget(widgetOptions);
});

This example demonstrates the basic integration of the TradingView Charting Library, including setting up the chart options and initializing the widget.

  1. Applying a Custom Theme:
// Define a custom theme
const customTheme = {
  "chart.backgroundColor": "#1e1e1e",
  "paneProperties.background": "#1e1e1e",
  "paneProperties.vertGridProperties.color": "#2c2c2c",
  "paneProperties.horzGridProperties.color": "#2c2c2c",
  "symbolWatermarkProperties.color": "#4c4c4c",
  "scalesProperties.textColor": "#eeeeee",
};

// Apply the custom theme to the chart
tvWidget.applyOverrides({
  "theme": customTheme
});

This example demonstrates how to apply a custom theme to the TradingView Charting Library, modifying the appearance of the chart.

  1. Interacting with the Chart:
// Add an event listener to the chart
tvWidget.onChartReady(function() {
  tvWidget.subscribe('onAutoSaveNeeded', function() {
    console.log('Chart state has changed, saving...');
    tvWidget.save(function(state) {
      // Save the chart state to the server
      saveChartState(state);
    });
  });
});

This example shows how to subscribe to chart events, such as the "onAutoSaveNeeded" event, and save the chart state when it changes.

  1. Updating the Chart Data:
// Update the chart data
tvWidget.onChartReady(function()

Competitor Comparisons

📊 Interactive JavaScript Charts built on SVG

Pros of ApexCharts.js

  • Easier to set up and use, with a simpler API
  • More customizable out of the box, with a wide range of chart types
  • Lightweight and faster rendering for simpler charts

Cons of ApexCharts.js

  • Less advanced features for financial charting
  • Limited support for real-time data updates
  • Fewer options for technical analysis tools

Code Comparison

ApexCharts.js:

var options = {
  chart: { type: 'candlestick' },
  series: [{ data: seriesData }]
};
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();

Charting Library Examples:

const widget = new TradingView.widget({
  symbol: 'NASDAQ:AAPL',
  interval: 'D',
  container_id: 'tv_chart_container',
  library_path: '/charting_library/'
});

ApexCharts.js offers a more straightforward setup for basic charts, while the TradingView Charting Library provides more advanced features for financial charting. ApexCharts.js is better suited for general-purpose charting needs, while the Charting Library Examples are tailored for complex financial data visualization and analysis.

Open-source JavaScript charting library behind Plotly and Dash

Pros of plotly.js

  • Open-source and free to use, with a large community and extensive documentation
  • Supports a wide range of chart types and customization options
  • Offers interactive features like zooming, panning, and hover tooltips out of the box

Cons of plotly.js

  • May have a steeper learning curve for complex visualizations
  • Performance can be slower for large datasets compared to TradingView's library
  • Less specialized for financial charting compared to TradingView's offering

Code Comparison

plotly.js:

Plotly.newPlot('myDiv', [{
  x: [1, 2, 3, 4],
  y: [10, 15, 13, 17],
  type: 'scatter'
}]);

Charting Library Examples:

new TradingView.widget({
  symbol: 'NASDAQ:AAPL',
  interval: 'D',
  container_id: 'tv_chart_container'
});

The plotly.js example shows a simple scatter plot creation, while the Charting Library Examples code demonstrates how to initialize a TradingView chart widget. plotly.js offers more flexibility for general-purpose charting, while the TradingView library is tailored for financial charts with pre-built features specific to that domain.

Highcharts JS, the JavaScript charting framework

Pros of Highcharts

  • More extensive documentation and examples
  • Wider range of chart types and customization options
  • Larger community and ecosystem

Cons of Highcharts

  • Commercial license required for most use cases
  • Steeper learning curve due to more complex API
  • Larger file size, potentially impacting page load times

Code Comparison

Highcharts:

Highcharts.chart('container', {
  series: [{
    data: [1, 2, 3, 4, 5]
  }]
});

Charting Library Examples:

new TradingView.widget({
  symbol: 'NASDAQ:AAPL',
  interval: 'D',
  container_id: 'tv_chart_container'
});

Summary

Highcharts offers a more comprehensive charting solution with extensive customization options, while the Charting Library Examples from TradingView focuses specifically on financial charting. Highcharts requires a commercial license for most use cases but provides a wider range of chart types. The Charting Library Examples may be more suitable for projects specifically focused on financial data visualization, while Highcharts is a versatile option for various charting needs across different industries.

    .attr("width", 400)
    .attr("height", 300);

svg.selectAll("rect")
    .data(data)
    .enter()
    .append("rect")
    .attr("x", (d, i) => i * 40)
    .attr("y", d => 300 - d * 10)
    .attr("width", 35)
    .attr("height", d => d * 10);

charting-library-examples:

const widget = new TradingView.widget({
    symbol: 'NASDAQ:AAPL',
    interval: 'D',
    container_id: 'tv_chart_container',
