I was looking for a lib like this 2 weeks ago and I've never heard about this one... Looks like it's the most stared repo and it's actively maintained, but the Github link is not on the first page of Google with the keywords "react chart". (Edit: the "official" site is in 6th position, I've probably missed it or didn't scroll up to it) Finally I've been using React Chartjs 2, based on Chartjs 2. https://github.com/gor181/react-chartjs-2 (157 stars, actively maintained) https://github.com/chartjs/Chart.js (26,256 stars, actively maintained)

FYI, samples/pie-customTooltips.html throws a JS error and doesn't load. I think your script include is missing the "dist" dir. I filed a Github issue here: https://github.com/chartjs/Chart.js/issues/2369 screenshot: http://i.imgur.com/so0iHU3.png

In Chart.js 2.0 Released

We're working on adding more comprehensive demos, embedded with CodePen so they can be edited and forked. Until that is done, you can see a number of examples here: https://github.com/chartjs/Chart.js/tree/master/samples

In Chart.js 2.0 Released

Well done for releasing v2.0. I really like Chart.js and would choose it over Highcharts due to the license restrictions of the latter. But... Highcharts handles multi-line labels effortlessly. Does Charts.js 2.0 solve this issue [0]? [0] https://github.com/chartjs/Chart.js/issues/608

We still need to add it to the docs, but here's a sample from the repo. https://github.com/chartjs/Chart.js/blob/master/samples/bubb...

In Chart.js 2.0 Released

One of the Chart.js contributors here. Version 2.0 is a massive overhaul of the underlying library focused on ease of use and extensibility. Hundreds of issues from the 1.x branch have been resolved, making Chart.js even more stable and user friendly than ever! Here are a few of the core changes: - Github Organization: Moved from github.com/nnnick/Chart.js to our own org, github.com/chartjs/Chart.js, where we hope to continue to grow the awesome community - Scales: New time axis, log axis and multiple axis support - Animations galore: Just about everything animates now, from adding/removing datasets, updating data or even changing colors. Based on canvas, animations run at 60fps even with tens of thousands of data points - Dynamic config: It used to be difficult to interact with a chart after creating it, but now it is as simple as changi

ng the object and calling the update function - Mixed charts: It is now trivial to put a line on a bar chart or whatever combination floats your boat - Legends: Now supported for all chart types, they can be placed anywhere on the canvas and support toggling data visibility by default - Chart types: More charts supported out of the box, including stacked area/bar and bubble charts - Labels: Built-in chart titles and axis labels make it easy to understand your data - Responsive and mobile ready: Charts, labels and legends all scale down to accommodate any screen size out of the box, with touch event support - too much awesomeness to list here Moving forward, the core team is committed to a faster release cycle. Version 2.1 is slated to come out in the next week with: - Plugin support: Add optional support for features like zoom/pan (forthcoming) without adding bulk to the core library - Shared data between charts We'd love your help, so please join and contribute! We have a very active Slack community that you can join at https://chartjs-slack-automation.herokuapp.com. We'd love to add new chart types and to get the documentation translated, so if you think you can help, we'd love to have you!
