# @connectedcars/react-native-slide-charts

[![Version](https://img.shields.io/npm/v/@connectedcars/react-native-slide-charts.svg)](https://www.npmjs.com/package/@connectedcars/react-native-slide-charts)
[![NPM](https://img.shields.io/npm/dm/@connectedcars/react-native-slide-charts.svg)](https://www.npmjs.com/package/@connectedcars/react-native-slide-charts)

`react-native-slide-charts` uses [`react-native-svg`](https://github.com/react-native-community/react-native-svg), [`d3`](https://github.com/d3/d3), and [`react-native-gesture-handler`](https://github.com/software-mansion/react-native-gesture-handler) to create highly customizable interactive charts that animate smoothly via [`Direct Manipulation`](https://facebook.github.io/react-native/docs/direct-manipulation).

## :warning: Note: The package have been moved from `react-native-slide-charts` to [`@connectedcars/react-native-slide-charts`](https://www.npmjs.com/package/@connectedcars/react-native-slide-charts) :warning:

### Peer Dependencies

#### Expo

All `peerDependencies` are included with [Expo](https://expo.io/) so installation of `peerDependencies` isn't required.

#### React Native

`@connectedcars/react-native-slide-charts` depends on two peer dependencies with native modules that must be installed alongside it. Follow the installation instructions for both iOS and Android both packages.

| Package                                                                                               | Minimum Version | Maximum Version |
| ----------------------------------------------------------------------------------------------------- | --------------- | --------------- |
| [`react-native-svg`](https://github.com/react-native-community/react-native-svg)                      | 7.0.0           | 11.x             |
| [`react-native-gesture-handler`](https://github.com/software-mansion/react-native-gesture-handler)    | 1.1.0           | 1.x             |

#### NOTICE:

Make sure the version of the native module packages chosen works with the `react-native` version of the project. Manually linking the projects may be required depending on the version and platform.

## Usage

`@connectedcars/react-native-slide-charts` exports two types of charts, `SlideAreaChart` and `SlideBarChart` along with the type definitions for the Charts, Props, and Enums.

```jsx
import {
  SlideAreaChart,
  SlideBarChart,
  SlideBarChartProps,
  SlideAreaChartProps,
  YAxisProps,
  XAxisProps,
  XAxisLabelAlignment,
  YAxisLabelAlignment,
  CursorProps,
  ToolTipProps,
  ToolTipTextRenderersInput,
  GradientProps,
} from '@connectedcars/react-native-slide-charts'
```

To get started you can render an empty chart:

```jsx
<SlideAreaChart />
```

But it will be more visually useful for configuring to use some test [data](#data).

```jsx
<SlideBarChart
  data={[
    { x: 0, y: 0 },
    { x: 1, y: 1 },
    { x: 2, y: 2 },
    { x: 3, y: 3 },
    { x: 4, y: 4 },
  ]}
/>
```

The Props, Types, Enums, and Defaults are defined below:

- [Charts](#charts)
  - [Common Props](#common-bar-and-area-chart-props)
  - [Bar Chart Props](#bar-chart-props)
  - [Area Chart Props](#area-chart-props)
