如何在Chart.js中显示工具提示？ [英] How to show tooltips in Chart.js?

问题描述

按照教程，此代码绘制折线图，​​但没有工具提示。我在这里缺少一些配置选项？在教程中显示了工具提示。

Following the tutorial this code draws the line chart, but no tooltips. Am I missing some configuration option here? In the tutorial there are tooltips showing up.

var chartData = {
    labels: ["January", "February", "March", "April", "May", "June", "July"],
    datasets: [
        {
            label: "My Second dataset",
            fillColor: "rgba(151,187,205,0.2)",
            strokeColor: "rgba(151,187,205,1)",
            pointColor: "rgba(151,187,205,1)",
            pointStrokeColor: "#fff",
            pointHighlightFill: "#fff",
            pointHighlightStroke: "rgba(151,187,205,1)",
            data: [28, 48, 40, 19, 86, 27, 90]
        }
    ]
};

var ctx = document.getElementById("chart").getContext("2d");
var myNewChart = new Chart(ctx).Line(chartData, {
    showTooltip: true,
    tooltipTemplate: "<%= value %>"
});

推荐答案

您使用的是什么版本的chart.js？

What version of chart.js are you using?

我可以使用v1.0.1-beta2确认工具提示

I can confirm that tooltips work using v1.0.1-beta2

<script src="//cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.1-beta.2/Chart.min.js"></script>

但不起作用使用v0.2.0 。

版本1.0.1-beta2可从cdnjs获取。

Version 1.0.1-beta2 is available from cdnjs.
