我使用chart.js创建了条形图,工作正常,但我需要在条形图上方添加标签。
任何1都可以帮助我 建议是最受欢迎的
chart.js版本1.2
以下用于条形图的画布
<canvas id="barChart" height="180"></canvas>
以下启动插件的代码
var barChartCanvas = $("#barChart").get(0).getContext("2d");
var barChart = new Chart(barChartCanvas);
var barChartData = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "Electronics",
fillColor: "rgb(210, 214, 222)",
