ReactNativeSimpleCharts

Simple charts with gradient for react-native.

• Allow to use multiple charts.
• Use chart with gradient filling.
• Customize charts: axis, height, steps OY and more other things.
• Chart automatically scale OY axis data and round OY values to usual perception.

Installation

Just paste in terminal npm install react-native-simple-charts --save && react-native link react-native-simple-charts && react-native link react-native-svg && react-native link react-native-blur

Usage

Simple Charts

import Chart from 'react-native-simple-charts'
...

  render() {
    let greenChartProps = {
      "strokeWidth": 2,
      "renderPoints": true,
      "strokeColor": 'green',
      "pointColor1": 'green',
      "pointColor2": 'green',
    }
    let blueChartProps = {
      "strokeWidth": 2,
      "renderPoints": true,
      "strokeColor": 'blue',
      "pointColor1": 'blue',
      "pointColor2": 'blue',
    }
    let data = [
      {
        "chart": [
          {
            "x": '1',
            "y": 10,
            "props": greenChartProps
          },
          {
            "x": '2',
            "y": 45,
            "props": greenChartProps
          },
          {
            "x": '3',
            "y": 10,
            "props": greenChartProps
          },
          {
            "x": '4',
            "y": 55,
            "props": greenChartProps
          },
          {
            "x": '5',
            "y": 20,
            "props": greenChartProps
          },
          {
            "x": '6',
            "y": 65,
            "props": greenChartProps
          },
        ],
      },
      {
        "chart": [
          {
            "x": '1',
            "y": 89,
            "props": blueChartProps
          },
          {
            "x": '2',
            "y": 67,
            "props": blueChartProps
          },
          {
            "x": '3',
            "y": 55,
            "props": blueChartProps
          },
          {
            "x": '4',
            "y": 23,
            "props": blueChartProps
          },
          {
            "x": '5',
            "y": 44,
            "props": blueChartProps
          },
          {
            "x": '6',
            "y": 55,
            "props": blueChartProps
          },
        ],
      }
    ]

    return (
      <Chart
          data={data}
          stepsOY={5}
      />
    );
  }

Gradient Chart

Note if you want to use chart with gradient filling it should be only one.

import Chart from 'react-native-simple-charts'
...

  render() {
    let greenChartProps = {
      "strokeWidth": 2,
      "renderPoints": true,
      "strokeColor": 'green',
      "pointColor1": 'green',
      "pointColor2": 'green',
    }
    let data = [
      {
        "chart": [
          {
            "x": '1',
            "y": 10,
            "props": greenChartProps
          },
          {
            "x": '2',
            "y": 45,
            "props": {
              ...greenChartProps,
              fillGradient: true,
              gradientEndColor: 'green',
              gradientStartColor: 'yellow'
            }
          },
          {
            "x": '3',
            "y": 10,
            "props": {
              ...greenChartProps,
              fillGradient: true,
              gradientEndColor: 'green',
              gradientStartColor: 'yellow'
            }
          },
          {
            "x": '4',
            "y": 55,
            "props": greenChartProps
          },
          {
            "x": '5',
            "y": 20,
            "props": greenChartProps
          },

            "x": '6',

            "props": greenChartProps
          },
        ],
      }
    ]

    return (
      <Chart
          data={data}
          stepsOY={5}
          axisTextColorActive={'red'}
          activeAxisXTextArray={['2', '3', '4']}
      />
    );
  }
