FLCharts

FLCharts is an easy-to-use library to build highly customizable bar, line and pie charts. It allows you to create your own chart bar UIView and use it to display data in the chart. Additionally FLCharts allows you to provide a custom HighlightedView to show the highlighted bar contents on top of the chart. Embed effortlessly your chart in a FLCard alogside with a title, an average vlue view and additional behaviours.
