## Introduction
Note: PatternFly React charts live in its own package at [@patternfly/react-charts](https://www.npmjs.com/package/@patternfly/react-charts)!
PatternFly React charts are based on the [Victory](https://formidable.com/open-source/victory/docs/victory-chart/) chart library, along with additional functionality, custom components, and theming for PatternFly. This provides a collection of React based components you can use to build PatternFly patterns with consistent markup, styling, and behavior.
Learn to build a stack chart using a Katacoda tutorial starting with a simple chart, adding multiple datasets, tooltips, axis labels, a legend, and concluding by changing the theme color. You'll learn how to use React chart components together to build a consistent user experience.

## Examples
### Basic with right aligned legend
```js
import React from 'react';
import { Chart, ChartAxis, ChartBar, ChartStack, ChartVoronoiContainer } from '@patternfly/react-charts';
`${datum.name}: ${datum.y}`} constrainToVisibleArea />}
domainPadding={{ x: [30, 25] }}
legendData={[{ name: 'Cats' }, { name: 'Dogs' }, { name: 'Birds' }, { name: 'Mice' }]}
legendOrientation="vertical"
legendPosition="right"
height={250}
name="chart1"
padding={{
bottom: 50,
left: 50,
right: 200, // Adjusted to accommodate legend
top: 50
}}
width={600}
>
```
### Horizontal with bottom aligned legend
```js
import React from 'react';
import { Chart, ChartAxis, ChartBar, ChartStack, ChartThemeColor, ChartVoronoiContainer } from '@patternfly/react-charts';
`${datum.name}: ${datum.y}`} constrainToVisibleArea />}
domainPadding={{ x: [30, 25] }}
legendData={[{ name: 'Cats' }, { name: 'Dogs' }, { name: 'Birds' }, { name: 'Mice' }]}
legendPosition="bottom"
height={275}
name="chart2"
padding={{
bottom: 75, // Adjusted to accommodate legend
left: 50,
right: 50,
top: 50
}}
themeColor={ChartThemeColor.gold}
width={450}
>
```
### Multi-color (ordered) horizontal with bottom aligned legend
This demonstrates an alternate way of applying tooltips using data labels.
```js
import React from 'react';
import { Chart, ChartBar, ChartAxis, ChartStack, ChartThemeColor, ChartTooltip } from '@patternfly/react-charts';
}
/>
}
/>
}
/>
}
/>
```
### Monthly data with responsive container
```js
import React from 'react';
import { Chart, ChartAxis, ChartBar, ChartStack, ChartTooltip, getResizeObserver } from '@patternfly/react-charts';
class MonthlyResponsiveStack extends React.Component {
constructor(props) {
super(props);
this.containerRef = React.createRef();
this.observer = () => {};
this.state = {
width: 0
};
this.handleResize = () => {
if(this.containerRef.current && this.containerRef.current.clientWidth){
this.setState({ width: this.containerRef.current.clientWidth });
}
};
this.bars = [];
for(let i = 1; i < 32; i++){
this.bars.push({ x: `Aug. ${i}`, y: Math.floor(Math.random() * 6) + 1 });
};
this.renderSocketBars = () => {
let socketBars = this.bars.map((tick, index) => {
return {
x: tick.x,
y: tick.y,
name: 'Sockets',
label: `${tick.x} Sockets: ${tick.y}`
};
});
return } />;
}
this.renderCoresBars = () => {
let coresBars = this.bars.map((tick, index) => {
return {
x: tick.x,
y: tick.y,
name: 'Cores',
label: `${tick.x} Cores: ${tick.y}`
};
});
return } />;
}
this.renderNodesBars = () => {
let nodesBars = this.bars.map((tick, index) => {
return {
key: index,
x: tick.x,
y: tick.y,
name: 'Nodes',
label: `${tick.x} Nodes: ${tick.y}`
};
});
return } />;
}
this.getTickValues = (offset = 2) => {
let tickValues = [];
for(let i = 1; i < 32; i++){
if (i % offset == 0){
tickValues.push(`Aug. ${i}`);
}
}
return tickValues;
}
}
componentDidMount() {
this.observer = getResizeObserver(this.containerRef.current, this.handleResize);
this.handleResize();
}
componentWillUnmount() {
this.observer();
}
render(){
const { width } = this.state;
return (
{ this.renderSocketBars() }
{ this.renderCoresBars() }
{ this.renderNodesBars() }
)
}
}
```
### Multi-color (unordered) responsive container
This demonstrates monthly data with a bottom aligned legend and responsiveness for mobile.
```js
import React from 'react';
import { Chart, ChartArea, ChartAxis, ChartStack, ChartLegendTooltip, ChartThemeColor, createContainer, getResizeObserver } from '@patternfly/react-charts';
class MultiColorChart extends React.Component {
constructor(props) {
super(props);
this.containerRef = React.createRef();
this.observer = () => {};
this.state = {
width: 0
};
this.handleResize = () => {
if(this.containerRef.current && this.containerRef.current.clientWidth){
this.setState({ width: this.containerRef.current.clientWidth });
}
};
}
componentDidMount() {
this.observer = getResizeObserver(this.containerRef.current, this.handleResize);
this.handleResize();
}
componentWillUnmount() {
this.observer();
}
render() {
const { width } = this.state;
// Note: Container order is important
const CursorVoronoiContainer = createContainer("voronoi", "cursor");
const legendData = [{ childName: 'cats', name: 'Cats' }, { childName: 'dogs', name: 'Dogs' }, { childName: 'birds', name: 'Birds' }];
return (
`${datum.y !== null ? datum.y : 'no data'}`}
labelComponent={ datum.x}/>}
mouseFollowTooltips
voronoiDimension="x"
voronoiPadding={50}
/>
}
legendData={legendData}
legendPosition="bottom-left"
height={225}
name="chart5"
padding={{
bottom: 75, // Adjusted to accomodate legend
left: 50,
right: 50,
top: 50,
}}
maxDomain={{y: 30}}
themeColor={ChartThemeColor.multiUnordered}
width={width}
>
);
}
}
```
## Documentation
### Tips
- See Victory's [FAQ](https://formidable.com/open-source/victory/docs/faq)
- For single data points or zero values, you may want to set the `domain` prop
- `ChartLegend` may be used as a standalone component, instead of using `legendData`
- Themes are inherited, so a default theme may override `themeColor` for a child component
- The `theme` and `themeColor` props should be applied at the most top level component
