Question 1

How do I update chart data dynamically in c3?

Accepted Answer

Use the load or unload API methods provided by c3 to update data in real-time; the library supports dynamic changes without full re-renders, making it suitable for dashboards with live data feeds.

Question 2

c3 vs Chart.js: which one should I use?

Accepted Answer

Choose c3 if you need D3's customization power with a simpler API, but prefer Chart.js for zero-dependency, lightweight charts with more built-in animation features and easier setup for common use cases.

Question 3

How to customize the appearance of c3 charts?

Accepted Answer

Leverage CSS for basic styling or tap into D3 via c3's API for deeper customizations; however, this requires D3 knowledge and can involve complex overrides, as noted in the documentation.

Question 4

Does c3 work well with React or Vue?

Accepted Answer

It can be integrated via wrappers or direct DOM manipulation, but lacks native framework components, so teams might prefer libraries like Recharts or Vue-chartjs for smoother integration.

Question 5

How to handle tooltips in c3 for better UX?

Accepted Answer

c3 provides built-in tooltips with configurable formats via the tooltip option, but advanced customizations may require overriding D3 functions, adding complexity.

Question 6

What are the performance implications of using c3 with large datasets?

Accepted Answer

Since c3 abstracts D3, it may introduce overhead for very large datasets; optimizing requires leveraging D3 directly or simplifying chart configurations, which can negate the ease-of-use benefit.
