react-native-graph is a Line Graph implementation based on the high performance 2D graphics rendering engine "Skia". It's used in the Pink Panda Wallet app to power thousands of token graphs every day.
- ποΈ Faster and smoother than react-native-svg graphs
- β‘οΈ Native path interpolation in Skia
- π Up to 120 FPS animations
- π Cubic bezier rendering for smoother edges
- π Smooth pan/scrubbing gesture
- π° Made for crypto apps and Wallets
- β Does not block navigation, press or scroll animations

const priceHistory = usePriceHistory('ethereum')
return <LineGraph points={priceHistory} color="#4484B2" />
}
Whether to animate between data changes.
Animations are ran using the Skia animation system and are fully natively interpolated to ensure best possible performance.
If animated
is false
, a light-weight implementation of the graph renderer will be used, which is optimal for displaying a lot of graphs in large lists.
Example:
<LineGraph
points={priceHistory}
animated={true}
color="#4484B2"
/>
Whether to enable the pan gesture.
Requires
animated
to betrue
.
There are three events fired when the user interacts with the graph:
onGestureStart
: Fired once the user presses and holds down on the graph. The pan gesture activates.onPointSelected
: Fired for each point the user pans through. You can use this event to update labels or highlight selection in the graph.onGestureEnd
: Fired once the user releases his finger and the pan gesture deactivates.
Example:
<LineGraph
points={priceHistory}
animated={true}
color="#4484B2"
enablePanGesture={true}
onGestureStart={() => hapticFeedback('impactLight')}
onPointSelected={(p) => updatePriceTitle(p)}
onGestureEnd={() => resetPriceTitle()}
/>
Used to render labels above or below the Graph.
Requires
animated
to betrue
.
Usually this is used to render the maximum and minimum values of the Graph. You can get the maximum and minimum values from your graph points array, and smoothly animate the labels on the X axis accordingly.
Example:
<LineGraph
points={priceHistory}
animated={true}
color="#4484B2"
TopAxisLabel={() => <AxisLabel x={max.x} value={max.value} />}
BottomAxisLabel={() => <AxisLabel x={min.x} value={min.value} />}
/>
Used to render the selection dot.
Requires
animated
andenablePanGesture
to betrue
.
If SelectionDot
is missing or undefined
, a default one is provided with an outer ring and light shadow.
Example:
<LineGraph
points={priceHistory}
animated={true}
color="#4484B2"
enablePanGesture={true}
SelectionDot={CustomSelectionDot}
/>
See this example <SelectionDot />
