Section 1.1: Customizing Default Labels

Victory provides the flexibility to modify the default label components. For example, if we wish to alter the orientation of the labels on our bar charts, we can achieve this by implementing the following:

import React from "react";

import { VictoryBar, VictoryLabel } from "victory";

export default function App() {

return (

// Your customized VictoryBar component here

);

}

By setting the angle of the VictoryLabel, we can present the labels vertically. Additionally, adjusting the textAnchor to "end" will align the labels to the right.

Section 1.2: Wrapping Components

We can also encapsulate components to tailor the display to our needs. For instance, creating a wrapper component allows us to add labels to our charts seamlessly:

import React from "react";

import { VictoryChart, VictoryLabel, VictoryScatter } from "victory";

const WrapperComponent = (props) => {

const renderChildren = () => {

const children = React.Children.toArray(props.children);

return children.map((child) => {

const style = { ...child.props.style, ...props.style };

return React.cloneElement(

child,

Object.assign({}, child.props, props, { style })

);

});

};

return (

// Your customized wrapper rendering logic here

{renderChildren()}

);

};

export default function App() {

return (

// Your VictoryScatter component here

);

}

The WrapperComponent takes in child components through the children prop and renders them using React.cloneElement, merging styles from both the child and the props. Within the App, we can render the VictoryScatter component inside the WrapperComponent to visualize a sine curve alongside VictoryLabel.

Section 1.3: Custom Point Components

To customize the displayed points, we can define a component, such as CatPoint, and pass it as the dataComponent in the VictoryScatter:

import React from "react";

import { VictoryChart, VictoryScatter } from "victory";

const CatPoint = (props) => {

const { x, y, datum } = props;

const cat = datum._y >= 0 ? "😀" : "😹";

return (

// Your point rendering logic here

{cat}

);

};

export default function App() {

return (

// Your customized VictoryScatter component here

);

}

By utilizing the datum prop, we can extract data entries, with the _y property providing the y-value. The x and y variables correspond to the point's position.
