How do I update charts in real-time with TOAST UI Chart?

Use the addData API along with the shift option in series settings to dynamically append new data points. Examples in the README show this for charts like Line and Area with smooth animations.

TOAST UI Chart vs Chart.js: which is better for my project?

TOAST UI Chart offers more chart types and built-in features like export and synchronized tooltips, making it better for complex dashboards. Chart.js is lighter and simpler, ideal for basic charts with minimal setup.

Can I use TOAST UI Chart with Angular?

There's no official Angular wrapper; you'd need to use the plain JavaScript version and integrate it manually, which requires extra effort compared to the supported React and Vue wrappers.

How to customize themes in TOAST UI Chart?

The library provides extensive theming options through configuration objects, allowing you to adjust colors, fonts, and styles. Detailed guides are available in the documentation for common themes and customizations.

How to export a chart as an image in TOAST UI Chart?

Leverage the export menu feature which supports PNG and JPEG formats. You can trigger exports programmatically or via UI elements, as described in the export capabilities section of the docs.

Does TOAST UI Chart support server-side rendering?

The README doesn't explicitly mention SSR; since it's a client-side library, server-side rendering might require additional setup, especially with the React or Vue wrappers, and could be limited by JavaScript dependencies.

Pros & Cons

Pros

Extensive Chart Variety

Supports over 20 chart types including statistical standouts like box plots and heatmaps, covering a wide range of data visualization needs as listed in the features.

Interactive and Responsive

Offers live data updates via the addData API, zoomable charts for Line/Area/Treemap, and synchronized tooltips, all with responsive design options demonstrated in the README.

Cons

Limited Framework Ecosystem

Only offers official wrappers for React and Vue; teams using Angular, Svelte, or other frameworks must rely on community solutions or custom integrations, which adds complexity.

Bundle Size Concerns

The comprehensive feature set, while powerful, likely results in a larger bundle size compared to lightweight alternatives like Chart.js, impacting performance for simple use cases.

Configuration Overhead

With numerous options for themes, responsiveness, and interactivity, setting up advanced charts can be intricate and require significant learning, as hinted by the detailed documentation.
