Javascript Chart Library with zoom and large data support [closed]

Question

Would anyone recommend a particular JavaScript charting library with zoom functionality, supporting large size data around 2,50,000/250K plotting points at once.

open source would be recommended.

Answer 1

My first thought would be either d3.js or ZingChart. d3 is open source, but the learning curve is pretty steep. ZingChart is closed, but much more approachable and provides support. Once you get into 50k+ points, other libraries tend to start having trouble.

PPS. Next time you may want to post in softwarerecs. Be sure to read their post guidelines.

Answer 2

Check the dyGraphs for this purpose. Have a look at the way it zooms:
