$ yarn add @connectedcars/react-native-slide-charts

Peer Dependencies

Expo

All peerDependencies are included with Expo 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`	7.0.0	11.x
`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.

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:

<SlideAreaChart />

But it will be more visually useful for configuring to use some test data.

<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

Common Bar and Area Chart Props:

boolean

true

Determines if the indicator for the chart should be visible always or just when being touched.For SlideAreaChart the indicator is the CursorMarker, CursorLine, and ToolTip.For SlideBarChart the indicator is the barSelectedColor or renderSelectedFillGradient and ToolTip.

boolean

true

Animates the charts on mounting and between prop updates.

number

0

Height of the area below the chart for the X-Axis markers and label to render in.

number

0

Width of the area left of the chart for the Y-Axis markers and label to render in.

(x: number
| Date)
=> void

undefined

Callback function that provides the current Cursor position x. As this is firing off of a continuous animation and not state the usage should match appropriately.e.g. This can be used in conjunction with an array of timed gps points to move an indicator along a path on a map.

(y: number)
=> void

undefined

Callback function that provides the current Cursor position y. As this is firing off of a continuous animation and not state the usage should match appropriately.e.g. This can be used with direct manipulation on a TextInput to display the current value outside the chart.

number

16

Pushes the rendered height of the data within the chart down to make room for the ToolTip at the max. The ToolTip will render outside of the chart component if desired so this can be set to 0, or adjusted for using paddingTop or style instead if desired.

Array<{
  x: number
  | Date,
  y: number
}>

[]

Data that will be displayed on the chart. This must be an array of objects with x and y values with the x increasing from index 0 onward as the chart does not sort the array before use and will render incorrectly otherwise.

string

undefined

Color to fill the bars of the bar chart or area of the area chart. Takes precedence over renderFillGradient when applied.

number

200

Height of the entire chart component.

() => void

undefined

If provided the chart will not be interactive and instead can be pressed.

number

0

Bottom padding as it can not be applied via style to the chart component.

number

8

Left padding as it can not be applied via style to the chart component.

number

8

Right padding as it can not be applied via style to the chart component.

number

0

Top padding as it can not be applied via style to the chart component.

(props:
GradientProps)
=> JSX.Element
| null

Default Area Chart Default Bar Chart

Function that takes GradientProps and returns a custom gradient to fill the bars of the bar chart or area of the area chart.

boolean

false

Ensure touch is passed to scrollView on y movement if component is inside scrollView.

boolean

true

Terminates touch outside the chart component.

(opacity: number)
=> void

undefined

If alwaysShowIndicator is false this function is fired with the current indicator opacity whenever the indicator appears or disappears.

ViewStyle

{backgroundColor:
'#fff'}

Style of chart component.

boolean

false

On some slower Android devices there may be too many calls across the bridge that it can cause some lagging of the indicator movement, this limits the calls to the queue on Android with little noticeable change in the interaction.

ToolTipProps

undefined

Props for rendering the ToolTip.

number

Dimensions
.get('window')
.width

Width of the entire chart.

XAxisProps

undefined

Props for rendering the XAxis.

(props:
GradientProps)
=> JSX.Element
| null

Default Selected Fill Gradient

Function that takes GradientProps and returns a custom gradient to fill the selected bar.

(bar: number)
=> void

undefined

This callback is fired when the bar selection has changed via touch. This can be used to fire off haptic feedback to the user, or for other side effects. If using expo selection feedback on iOS using expo-haptics is suggested.

Area Chart Props:

CursorProps

{cursorMarkerHeight: 24,
cursorMarkerWidth: 24,

number

4

The axis marker labels are top justified below the chart, this is the space between the marker and the chart.

number

0

The first and last marker are always shown then the rest are laid out left to right; if the marker before the final one would layout closer than markerSpacing to the final marker, this can be avoided with minimum spacing. This is also useful in making room for a specialEndMarker.
