WilliamChart各种图表效果实现大全

WilliamChart各种图表效果实现大全，有水平线条表格，有柱状表格等。
由LineFragment，BarFragment，StackedFragment，SandboxFragment几个fragment封装实现几种效果。
DrawerFragment来实现简单框架。并且提供接口

项目部分源码如下：

    /**
     * Callbacks interface that all activities using this fragment must implement.
     */
    public interface NavigationDrawerCallbacks {

        void onNavigationDrawerItemSelected(int position);
    }

给首页回调。
首页MainActivity implements DrawerFragment.NavigationDrawerCallbacks
实现方法用来切换fragment

    @Override
    public void onNavigationDrawerItemSelected(int position) {

        switch (position){
            case 0:
                getSupportFragmentManager().beginTransaction()
                        .replace(R.id.container, new LineFragment())
                        .commit();
                break;
            case 1:
                getSupportFragmentManager().beginTransaction()
                        .replace(R.id.container, new BarFragment())
                        .commit();
                break;
            case 2:
                getSupportFragmentManager().beginTransaction()
                        .replace(R.id.container, new StackedFragment())
                        .commit();
                break;
            case 3:
                mCurrFragment = new SandboxFragment();
                getSupportFragmentManager().beginTransaction()
                        .replace(R.id.container, mCurrFragment)
                        .commit();
            default:
                break;
        }
    }
