I'm trying to migrate Chart.js from 2.9.3
to 3.3.0
and even after applying the the changes (https://www.chartjs.org/docs/latest/getting-started/v3-migration.html) I'm still getting the error:
Error: "category" is not a registered scale
.
This is what I have
Chart.register(BarController, DoughnutController, LineController, PieController);
new Chart(this.id, {
type: 'bar',
data,
options: {
responsive: true,
maintainAspectRatio: false,
plugins: {
title: {
display: options.plugins.title ? true : false,
},
tooltip: {
mode: 'index',
intersect: false
},
scales: {
x: {
stacked: true,
gridLines: {
drawBorder: false,
display: false,
},
ticks: {
autoSkip: true,
maxTicksLimit: 13,
},
},
y: {
stacked: true,
gridLines: {
color: '#e6e6e6',
drawBorder: false,
},
}
}
});
What could I be missing here?
What is the categoryscale? That is the default x axis type. Category scale is the scale type with labels you provide, so since he does not change the type of his x axis he is using the category scale, and because the error says so If you are using react-chartjs-2.
Category scale is the scale type with labels you provide, so since he does not change the type of his x axis he is using the category scale, and because the error says so If you are using react-chartjs-2. import { Chart as ChartJS } from 'chart.js/auto' import { Chart } from 'react-chartjs-2'
For Error: "arc" is not a registered scale in a doghnut chart, you can solve it also by import {ArcElement,Chart} from 'chart.js' and register ArcElement using Chart.register (ArcElement). We have seen how to plot doughnut and bar charts using the famous library of chart.js, and how to solve the problem of a registered scale.
Like the error says you are using the category scale
so you will need to import and register it like so: import {CategoryScale} from 'chart.js'; Chart.register(CategoryScale)
.
Or you can choose to not use treeshaking and import everything like so: import Chart from 'chart.js/auto'
.
For all available things you might need to import and register please take a look here: https://www.chartjs.org/docs/3.3.0/getting-started/integration.html#bundlers-webpack-rollup-etc
