My attempt at implementing a better time series charting library, based on d3.js

Motivations and Design Ideas

I learned a lot from my experience working on NVD3. I wanted to take the lessons learned from that project to build a better charting library.

Here are some guidelines I'd like to apply to this library:

  • Better data cleanup. Having the library take care of filling in missing points.
  • For large datasets, charts should reduce resolution of the lines for performance gain.
  • Better margin auto adjusting.
  • Easier ability to integrate different chart types into the same plot (line, area, scatter, bars)
  • Easier ability to add horizontal and vertical line markers.
  • Adding and removing data points in real time should be seamless.
  • Ability to use data generators (so you can write functions like y=x^2).
  • Removal of the chart legend, with hooks to enable series'. Allows developer to create their own legend.
  • Provide an AngularJS and React.js companion library.
  • No need to create your own SVG tag. Library creates it for you and sizes it to the container.
  • Code is tested and linted properly. Written in CoffeeScript.

Development

To build the project, run the following

npm install
npm test
