highcharts - Highcharts 加载图像

Question

使用http://api.highcharts.com/highcharts#loading

是否可以将图像作为显示的叠加层的一部分？特别是“加载” gif 图像？

我试过使用 labelStyle 部分，但到目前为止还没有运气！

Answer 1

在检查 API 之后。这似乎是可能的。

labelStyle接受任何有效的 CSS。通常带有连字符的属性会删除连字符，并将下一个字母大写。这意味着我们可以使用类似的东西background-image来提供背景图片（比如加载.gif）。

var chart = new Highcharts.Chart({
    // ...

    loading: {
        labelStyle: {
            backgroundImage: 'url("http://jsfiddle.net/img/logo.png")',
            display: 'block',
            width: '136px',
            height: '26px',
            backgroundColor: '#000'
        }
    },

    // ...
});

查看此示例以进行自定义加载

$(function () {
    // the button handler
    var isLoading = false,
        $button = $('#button');
    $button.click(function() {
        if (!isLoading) {
            chart.showLoading();
            $button.html('Hide loading');
        } else {
            chart.hideLoading();
            $button.html('Show loading');
        }
        isLoading = !isLoading;
    });
    
    
    // create the chart
    var chart = new Highcharts.Chart({
        chart: {
            renderTo: 'container'
        },
        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },
        
        series: [{
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
