F2Native is born for mobile visual development. It is out-of-the-box,cross-platform, high-performance visualization solution . Support Android and iOS perfect,moreover have high-performance experience in low-end mobile. Based on the grammar of graphics, F2Native provides all the chart types you'll need. Our mobile design guidelines enable better user experience in mobile visualzation projects.

Special thanks to Leland Wilkinson, the author of The Grammar Of Graphics, whose book served as the foundation for F2Native and F2.

Supports iOS 9.0+,Xcode 9.0+

1. DownLoad all content of F2Native.
   
2. Execute the following command to pull the associated submodule.
   

git submodule init
git submodule update 

3. Add the project under the iOS folder in F2 to your project.
   
4. import <F2/F2.h>
   

1. Build GCanvas

sh build_gcanvas_android.sh

2. Build F2Native

./gradlew :android:f2native:assembleStandalone

3. run Demo

./gradlew :android:sample:installStandaloneD

F2Native supports iOS and Android. Using the cross-platform language C++ to generate the underlying drawing commands， can achieve cross-platform, unified experience, high-performance experience.

make data more alive and chart interactions more natural.

With the power of grammar of graphics, F2Native including classical charts such as line, column/bar chart, pie chart. Additionally, F2 also provides feature-riched chart components to meet various needs.
