Ask HN: What are your favorite JavaScript charting libraries?

Requirements:

  * Line plots with time-based x-axis
  * Free to use
  * Mobile friendly

I like Dygraphs.

The documentation could be better but the library is very feature-rich and customizable.

In addition to chartjs which has already been mentioned, we like http://www.highcharts.com/

Free for non-commercial, $99 per website, and about $500 for most other uses.

The API is clean and easy to learn. Their support has always been top notch for us.

If an option like HighCharts is on the table, it is worth checking out http://www.zingchart.com

Free branded version and a variety of licenses available. Flexible styling and no plugins required.
