  const _goBack = () => console.log('Went back');

  const _handleSearch = () => console.log('Searching');

  const _handleMore = () => console.log('Shown more');

  return (
    <Provider>
    <Appbar.Header style={styles.header}>
      <Appbar.BackAction onPress={_goBack} />
      <Appbar.Content title="My App" subtitle="Subtitle" />
      <Appbar.Action icon="magnify" onPress={_handleSearch} />
      <Appbar.Action icon="dots-vertical" onPress={_handleMore} />
    </Appbar.Header>
      <View style={styles.mainbox}>
        <Text>Bezier Line Chart</Text>
        <LineChart
          data={{
            labels: ["January", "February", "March", "April", "May", "June"],
            datasets: [
              {

            ]
          }}
          width={330} // from react-native
          height={220}
          yAxisLabel="$"
          yAxisSuffix="k"
          yAxisInterval={1} // optional, defaults to 1
          chartConfig={{
            backgroundGradientFrom: "#218838",
            backgroundGradientTo: "#218838",
            decimalPlaces: 2, // optional, defaults to 2dp
            color: (opacity = 1) => `rgba(255, 255, 255, ${opacity})`,
            labelColor: (opacity = 1) => `rgba(255, 255, 255, ${opacity})`,
            style: {
              borderRadius: 16
            },
            propsForDots: {
              r: "6",
              strokeWidth: "2",
              stroke: "#218838"
