使用CSS在React Native中创建自定义图表

import React from 'react';
import { StyleSheet, View } from 'react-native';
import { LineChart } from 'react-native-chart-kit';

const data = {
  labels: ['January', 'February', 'March', 'April', 'May', 'June'],
  datasets: [
    {
      data: [20, 45, 28, 80, 99, 43],
      color: (opacity = 1) => `rgba(255, 0, 0, ${opacity})`, // 设置线条颜色
      strokeWidth: 2 // 设置线条宽度
    }
  ]
};

const ChartComponent = () => {
  return (
    <View style={styles.container}>
      <LineChart
        data={data}
        width={300}
        height={200}
        chartConfig={{
          backgroundGradientFrom: '#fff',
          backgroundGradientTo: '#fff',
          decimalPlaces: 0,
          color: (opacity = 1) => `rgba(0, 0, 0, ${opacity})`, // 设置标签和轴的颜色
        }}
        bezier
        style={styles.chart}
      />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  chart: {
    marginVertical: 8,
    borderRadius: 16,
  },
});

export default ChartComponent;
