React Native plugin for rendering charts that used to use ART, but now switched to react-native-svg
The goal of ARTy Charty is to produce animated, interactive, performant charts. It uses React Native ART to render the charts. Arty Charty does not rely on 3rd party libraries, such as D3, to produce the charts. This keeps the size of the library small (<80kb uncompressed and not-minified) and chart generating functions can be optimised for speed.
We noticed some issues with the ART library, so we switched to use react-native-svg instead.
npm i --save arty-charty
You also need to have react-native-svg
in your project. You can find instructins on how to install it here.
For more advanced usage have a look at the demo app here.
The ArtyCharty component is used to display line, spline, area, area-spline and bars charts. Charts can be stacked on top of each other by passing in an array of charts. Each chart object in the array needs to specify the kind of chart it is (line, spline, area, area-spline or bars) and an array of data points, where each data point needs to have a value field, which will be used as the value on the Y axis.
import { ArtyCharty } from 'arty-charty';
...js
<ArtyCharty data={[{
type: 'line',
data: [{value: 2}, {value: 3}, {value: 1}]
}]}/>
import { ArtyCharty } from 'arty-charty';
...
<ArtyCharty

{
type: 'area',
data: [{value: 3.48}, {value: 1.38}, {value: 6.73}, {value: 4.62}, {value: 3.14}],

For the line and pie chart there is also a spark (inline chart) component, which are light-weight versions of their full chart components. Axes, animations, click interactions have been removed and the ability to stack charts.

If you find bugs or have any suggestions, please open an issue. Pull requests are also welcome. All charts are rendered as SVG paths, have a look at this CodePen if you want to get more familiar with SVG paths and how we use them to generate charts.
-
Better documentation, add default values to parameter tables
-
Add more parameters: [markerRadius, selectedMarkerRadii, markerColor, selectedMarkerColors, yAxis stuff, xAxis, animation stuff] and imporve parameter names
-
More chart types [stacked-columns]
-
Nicer animations for adding/removing data points from the chart
-
Editable/draggable points with onValueChange callback function
-
Try replacing panlistener transformX with offset in render function, that can also be used to render only points shown on the screen!!!
