Otimize a clareza do gráfico com largura automática

Julho 9, 2026
O LightningChart JS Trader oferece escalonamento automático de candlestick e largura de barra para melhorar a legibilidade do gráfico e maximizar a visibilidade dos dados durante o zoom.

LightningChart JS Trader is a JavaScript/TypeScript library developed by LightningChart that specifically targets the creation of financial and trading applications. It provides high-performance, 2D, 3D, and real-time charting controls and a comprehensive suite of visualizations including candlestick, bar, line, and various technical indicators and drawing tools. This library enables software developers to create interactive technical analysis tools without the need for server-side setup as it runs completely on the client device.

LightningChart JS Trader automatically adjusts the width of candlesticks and bars as users zoom, improving chart readability and making more effective use of available space. By reducing unnecessary gaps between data points, it provides a clearer view of price movements and trends at different zoom levels without requiring manual configuration. This helps developers deliver more intuitive financial charting experiences while retaining the option to disable the feature when fixed-width rendering is preferred.

LightningChart JS Trader is licensed per developer and is available as an annual license with 1 year support. See our LightningChart JS Trader licensing page for full details.
