我最终遇到的是空白页和错误
TypeError:无法读取未定义的属性'getBasePixel'
,页面上没有图表。我是vue.js的新手,所以可能完全使用了错误,但是我尝试主要使用vue-chartjs页面中的演示。和chart.js页面。好像是我搞砸了,但看不到哪里。有人报告铬。任何帮助,将不胜感激。尝试引入一些数据流..2确切地说。...
CHARTS.JS
import { Scatter, mixins } from 'vue-chartjs'
const { reactiveProp } = mixins
export default {
extends: Scatter,
mixins: [reactiveProp],
props: ['options'],
mounted () {
// this.chartData is created in the mixin.
// If you want to pass options please create a local options object
this.renderChart(this.chartData, this.options)
}

答案 0 :(得分:1)
问题出在额外的数据集参数xAxisID
和yAxisID
上。
似乎它们的设置不正确,因此当vue-charts尝试获取对这些DOM元素的引用时,它会得到undefined
,从而导致错误。
您应该删除这些参数,或添加这些元素(通过选项或手动添加)
Here is a working version of the app
PS:此外,如果需要从[-100,100]间隔中获取随机数,则应使用Math.round(Math.random() * 200) - 100
。
在您的版本中,它总是返回1或0(因为Math.random不带参数,并且总是返回1到0之间的值)
