<canvas id="myChart" width="400" height="400"></canvas>
<script> $(function () { var ctx = document.getElementById("myChart").getContext('2d'); var myChart = new Chart(ctx, { type: 'bar', data: { labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"], datasets: [{ label: '# of Votes', data: [12, 19, 3, 5, 2, 3], 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: [ 'rgba(255,99,132,1)', 'rgba(54, 162, 235, 1)', 'rgba(255, 206, 86, 1)', 'rgba(75, 192, 192, 1)', 'rgba(153, 102, 255, 1)', 'rgba(255, 159, 64, 1)' ], borderWidth: 1 }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero:true } }] } } }); }); </script>

Then show it on the page

class ChartjsController extends Controller { public function index(Content $content) { return $content ->header('Chartjs') ->body(new Box('Bar chart', view('admin.chartjs'))); } }

 

拓展：

　　折線圖和柱狀圖一塊兒使用

　　

<canvas id="myChart1" width="400" height="400"></canvas>
<script> $(function () { var ctx = document.getElementById("myChart1").getContext('2d'); var myChart = new Chart(ctx, { type: 'bar', data: { labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"], datasets: [{ label: '# of Votes',
　　　　　　　　　　//數據類型 折線圖 type: "line", data: [12, 19, 3, 5, 2, 3], backgroundColor:'rgba(54, 162, 235, 0.1)', borderColor:'rgba(255,99,132,1)', borderWidth: 1 },{ label: '# of Votes',
　　　　　　　　　　//數據類型 柱狀圖 type: "bar", data: [16, 13, 11, 15, 2, 3], 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: [ 'red', 'rgba(54, 162, 235, 1)', 'rgba(255, 206, 86, 1)', 'rgba(75, 192, 192, 1)', 'rgba(153, 102, 255, 1)', 'rgba(255, 159, 64, 1)' ], borderWidth: 1 }] }, options: {
　　　　　　　　//顯示數值 "animation": { "duration": 1, "onComplete": function() { var chartInstance = this.chart, ctx = chartInstance.ctx; ctx.font = Chart.helpers.fontString(Chart.defaults.global.defaultFontSize, Chart.defaults.global.defaultFontStyle, Chart.defaults.global.defaultFontFamily);
　　　　　　　　　　　　//設置字體顏色 ctx.fillStyle = "black"; ctx.textAlign = 'center'; ctx.textBaseline = 'bottom'; this.data.datasets.forEach(function(dataset, i) { var meta = chartInstance.controller.getDatasetMeta(i); meta.data.forEach(function(bar, index) { var data = dataset.data[index]; ctx.fillText(data, bar._model.x, bar._model.y - 5); }); }); } }, scales: { yAxes: [{ ticks: { beginAtZero:true } }] } } }); }); </script>
