Two of the most charts used in this example.
First Chart using LineaChartView.
Second Chart using CombinedChartView.
Both of them share a formater for transform double values (1.0, 2.0...) to Strings, in this case the months.
To be able to install you need to first install cocopads and update to the latest version if possible.
Charts requires CocoaPods version >= 1.5.0
Once you have it installed, just use $Pod install .
