react-native-touchable-graph

React Native component for simply creating a graph, without any iOS or Android issue of touch.

Motivation

Victory Native is a great library, but there are tons of problems with the touch behaviour, because it is based on react-native-svg. The idea is to make a wrapper which replace the touchable svg element with react native Touchable component, so you are sure that it will work great both on Android and iOS.

Example app

Android example	Ios example

Installation

1. Install library and react-native-svg

   npm i --save victory-native react-native-svg
   

   Then, if victory-native version >= 0.16.6

    npm i --save react-native-touchable-graph
   

   else

    npm i --save react-native-touchable-graph@0.0.138
   

2. Link native code for SVG

   react-native link react-native-svg
   

Usage

Use as follows:

import { VictoryAxis, VictoryBar, VictoryChart, VictoryArea } from 'victory-native'
import TouchableGraph from 'react-native-touchable-graph';

const data = [
  { x: 1, y: 13000 },
  { x: 2, y: 16500 },
  { x: 3, y: 14250 },
  { x: 4, y: 19000 }
];


<TouchableGraph
  onPressBar={(data) => { console.log(data) }}
  onPressTickAxis={(data) => { console.log(data) }}
  >
  <VictoryChart>
    <VictoryAxis
      crossAxis
      orientation="left"
    />
    <VictoryAxis 
      dependentAxis
      crossAxis
      orientation="bottom"
    />
    <VictoryBar
      data={data}
    />
    <VictoryArea
