This is my first time working with Chart Js and I managed to get it displaying on my page but the keys 'label', 'backgroundColor', 'borderColor', and 'borderWidth' won't display. The keys 'labels' and 'data' work just fine as I can see the labels and the bars in the chart. I tried assigning the non-displaying keys to variables just like 'labels' and 'data' to see if it would work that way but no luck. I also tried passing hex colors and regular color names like red, blue, etc. but that didn't work either. If anyone could provide some assistance it would be greatly appreciated, thanks!

import React, { Component } from 'react';
var Chart = require("react-chartjs").Bar;
class BarChart extends Component {
capitalize(name) {
return name.charAt(0).toUpperCase() + name.slice(1);
}
render() {
var pokeLabels = this.props.stats.map((label) => {
return this.capitalize(label.stat.name)
})
var pokeDataSet = this.props.stats.map((set) => {
return set.base_stat
})
console.log(this.props.stats);
var data = {
labels: pokeLabels,
datasets: [
{
label: 'Pokemon Stats',
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'

borderColor: [

export default BarChart;
In a chart, click to select the data series for which you want to change the colors. On the Format tab, in the Current Selection group, click Format Selection. tab, expand Fill, and then do one of the following: To vary the colors of data markers in a single-series chart, select the Vary colors by point check box.
There are several npm packages that allow charts to be created in React; chart. js is one of the packages which makes the creation of charts and graphs very easy. The React wrapper for chart.
With ChartJS 3, you can change the color of the labels by setting the scales. x. ticks. color and scales.
So I was able to get the colors working by doing this:
datasets: [
{
label: "My First dataset",
fillColor: ["rgba(0,10,220,0.5)","rgba(220,0,10,0.5)","rgba(220,0,0,0.5)","rgba(120,250,120,0.5)" ],
strokeColor: "rgba(220,220,220,0.8)",
highlightFill: "rgba(220,220,220,0.75)",
highlightStroke: "rgba(220,220,220,1)",
data: pokeDataSet
}
