如何删除无法创建图表：与Ruby on Rails结合使用时，无法从给定项目错误获取上下文？

Question

I installed frappe charts for ruby on rails through gem.

Then I tried to run one of the frappe-chart code which is given in their website :

  let data = { labels: ["12am-3am", "3am-6am", "6am-9am", "9am-12pm", "12pm-3pm", "3pm-6pm", "6pm-9pm", "9pm-12am"], datasets: [ { title: "Some Data", values: [25, 40, 30, 35, 8, 52, 17, -4] }, { title: "Another Set", values: [25, 50, -10, 15, 18, 32, 27, 14] }, { title: "Yet Another", values: [15, 20, -3, -15, 58, 12, -17, 37] } ] }; let chart = new Chart({ parent: "#note-graph", // or a DOM element title: "My Awesome Chart", data: data, type: 'bar', // or 'line', 'scatter', 'pie', 'percentage' height: 250, colors: ['#7cd6fd', 'violet', 'blue'], // hex-codes or these preset colors; // defaults (in order): // ['light-blue', 'blue', 'violet', 'red', // 'orange', 'yellow', 'green', 'light-green', // 'purple', 'magenta', 'grey', 'dark-grey'] format_tooltip_x: d => (d + '').toUpperCase(), format_tooltip_y: d => d + ' pts' }); 

 <canvas id="note-graph"></canvas> 

I also tried with div instead of canvas but it's always showing the same error.

Answer 1

Im using laravel + vuejs.

this solved my problem with "Error: No parent element to render on was provided." with frapped

with the sample data that the npm provided,

in de data just declare the data varible like this:

 <template> <div> <h1>CHARTS</h1> <div id="chart"></div> </div> </template> <script> import { Chart } from 'frappe-charts/dist/frappe-charts.esm.js' // import css import 'frappe-charts/dist/frappe-charts.min.css' export default{ data(){ return{ data : { labels: ["12am-3am", "3am-6pm", "6am-9am", "9am-12am", "12pm-3pm", "3pm-6pm", "6pm-9pm", "9am-12am" ], datasets: [ { name: "Some Data", type: "bar", values: [25, 40, 30, 35, 8, 52, 17, -4] }, { name: "Another Set", type: "line", values: [25, 50, -10, 15, 18, 32, 27, 14] } ] }, chart : null // THIS IS WHAT YOU NEED TO SET NULL } }, methods:{ setChart(){ // IN METHOD YOU SET A NEW CHART this.chart=new Chart("#chart", { title: "My Awesome Chart", data: this.data, type: 'axis-mixed', height: 250, colors: ['#7cd6fd', '#743ee2'] }) } }, mounted(){ this.setChart(); // CALL THE METHOD IN A lifecycle hook } } </script>
