JSFiddle - React, Tailwind, and code Playground

HTML

<script src="https://canvasjs.com/assets/script/canvasjs.min.js"></script>
<br/><!-- Just so that JSFiddle's Result label doesn't overlap the Chart -->
<div id="chartContainer" style="height: 360px; width: 100%;"></div>

JavaScript

var chart = new CanvasJS.Chart("chartContainer", {
 title: {
    text: "Aligning Label Text to Left"

  axisX: {    
    labelMaxWidth: 100,
    labelBackgroundColor: "#d3d3d3",
    labelTextAlign: "left" // should align the left sides of the labels with each other
  },		
  axisY: {    
    labelMaxWidth: 100,    
    labelTextAlign: "left" // "right and "center" don't have any effect
  },
