import { Chart, Line, Axis, Tooltip } from 'react-native-statistic-charts'

// init chart data
const data = [
  {
    date: '2017-06-05',

  // render
  <Chart data={data} style={{ width: 500, height: 250, padding: [10, 20, 0, 20] }}>
    <Axis field="date" lineStyle={{ strokeColor: '#aaa' }} tickLineStyle={{ strokeColor: '#ccc' }} />
    <Axis field="value" lineStyle={{ strokeWidth: 0 }} tickLineStyle={{ strokeWidth: 0 }} grid />
    <Line position="date\*value" size={2} />
    <Tooltip
