我在Chrome控制台中遇到错误：
Uncaught TypeError: easingFunction is not a functionanimation.render @ Chart.js:1423Chart.animationService.startDigest @ Chart.js:1158Chart.animationService.digestWrapper @ Chart.js:1136
我正在使用的选项：
options: {animation:true, animationSteps: 60, animationEasing: easeOutQuart", responsive:true, maintainAspectRatio: false,}
分支中的Chart.js是默认的一切。
Chart.defaults.global.animation = {
duration: 1000,
easing: "easeOutQuart",
onProgress: function() {},
onComplete: function() {},
};
Chart.Animation = Chart.Element.extend({
currentStep: null, // the current animation step
numSteps: 60, // default number of steps
easing: "", // the easing to use for this animation
render: null, // render function used by the animation service
onAnimationProgress: null, // user specified callback to fire on each step of the animation
onAnimationComplete: null, // user specified callback to fire when the animation finishes
});
