Line chart displays series of data points in the form of lines. It can be used to show trend data, or comparison of different data sets. XY chart is used to plot points by specifying their XY coordinates. A bar chart provides a way of showing data values represented as vertical bars.

C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more. C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3. C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered. C3 enables deeper integration of charts into your application. Because of the dependence on D3, C3 supports only modern browsers D3 supports. For IE9 and IE10, polyfill is required because c3 uses MutationObserver, which is not supported in those versions. However, it's not required if charts always will be binded to the DOM specified by bindto because MutationObserver is not called in that case.

You may think that this is just yet an other charting library. But Chartist.js is the product of a community that was disappointed about the abilities provided by other charting libraries. Of course there are hundreds of other great charting libraries but after using them there were always tweaks you would have wished for that were not included. Are you planning to use Chartist to create a nice Dashboard or Admin UI? Don't loose any time and kickstart your development using the awesome templates by Creative Tim. They include Chartist and come with awesome chart styles! Specifying the style of your chart in CSS is not only cleaner but also enables you to use awesome CSS animations and transitions to be applied to your SVG elements! Note that CSS3 animations on SVG CSS attributes are not supported on all browsers and the appearance may vary.

Charting library for Android compatible with API 8+(Android 2.2). Works best when hardware acceleration is available, so API 14+(Android 4.0) is recommended. Apache License 2.0. Line chart (cubic lines, filled lines, scattered points), column chart (grouped, stacked, negative values), pie chart, bubble chart, combo chart (columns/lines), preview charts (for column chart and line chart), zoom (pinch to zoom, double tap zoom), scroll and fling. Custom and auto-generated axes (top, bottom, left, right, inside), and animations. Code of a demo application is in hellocharts-samples directory, requires appcompat v21. The demo app is also ready for download on Google Play. Every chart view can be defined in layout xml file or created in code and added to layout later. After the chart data has been set you can still modify its attributes but right after that you should call set*ChartData() method again to let chart recalculate and redraw data.
