'How do I implement percent values per slice of information in Victory Pie component
I would like to add a percentage value per slice of the doughnut chart, but I can't seem to figure out how. Also the data is dynamic not static, which means if there is another item added it needs to be able to recalculate and give accurate percentage per slice. This is the code below which shows the component of home, where there is data being fetched from the server side and getting the results. Then there is a variable called pie data results that maps and stores the occupation and values, and that is being passed as a prop down in the victory pie component.
import React, { Fragment, useState, useEffect } from "react";
//import DoughnutChart from "./DoughnutChart";
//import { Doughnut } from "react-chartjs-2";
import { Chart as ChartJS, ArcElement, Tooltip, Legend } from "chart.js";
//import { toast } from "react-toastify";
import "./pagecss/home.css";
import * as V from "victory";
import { VictoryPie } from "victory";
// import pieChartBasic from "./DoughnutChart";
// import { Doughnut } from "react-chartjs-2";
// import { FontAwesomeIcon } from "@fontawesome-free-solid";
// import { encryptStorage } from "./encrypt";
const Home = ({ setAuth }) => {
const [username, setUsername] = useState("");
const [user_id, setuserid] = useState("");
const [occ, setOcc] = useState([]);
// const [personalForm, setpersonalForm] = useState([]);//
// const [Pform, setform] = useState(false);
async function getUsername() {
try {
const response = await fetch("http://localhost:4001/home/", {
method: "GET",
//pass token with localstorage because it is stored in the header
headers: { token: localStorage.token },
});
const parseRes = await response.json();
// setpersonalForm(parseData);
setUsername(parseRes.username);
setuserid(parseRes.user_id); //
// const encryptStorage = new EncryptStorage('secret-key');
// encryptStorage.setItem("user_id", parseRes.user_id);
console.log(parseRes);
} catch (err) {
console.error(err.message);
}
try {
const response = await fetch("http://localhost:4001/results/occ", {
method: "GET",
//pass token with localstorage because it is stored in the header
headers: { token: localStorage.token },
});
const parseRes = await response.json();
// setpersonalForm(parseData);
setOcc(parseRes.data.occupationResults);
console.log(parseRes.data.occupationResults);
} catch (err) {
console.error(err.message);
}
}
//going to make a request when we get to this component, this is for getting from database
useEffect(() => {
getUsername();
}, []);
// const PIEDATAVALUES = occ.map((occupation) =>
// { "x"= occupation.occupation,
// "y"= occupation.values
// },
// );
// console.log(PIEDATAVALUES);
const result = [];
const piedataresults = occ.reduce((a, item) => {
result.push({ x: item.occupation, y: item.values });
return result;
}, []);
//console.log(piedataresults);

It is a long established fact that a reader will be distracted by
the readable content of a page when looking at its layout. The point
of using Lorem Ipsum is that it has a more-or-less normal
distribution of letters, as opposed to using 'Content here, content
here', making it look like readable English.

Hi my name is Alexey Aulov I am a senior at College of Staten
Island studying Information System and Informatics. I had the
original idea of Essential Health after I witnessed that
sometimes the best way for people to get mental help is to have
Therapist that can relate to you as much as possible to help you
out. Helping people gives me the most gratitude in life.
