Highcharts loading image

问题

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

Is it possible to have an image as part of the overlay that is shown? specifically a "loading" gif image?

I've tried using the labelStyle section, but no luck so far!

回答1:

After examining the API. This does seem to be possible.

labelStyle accepts any valid CSS. Properties that are normally hyphenated remove the hyphen, and capitalize the next letter. This means we can use something like background-image to supply a background image (like a loading .gif).

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

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

    // ...
});

Checkout this example for custom loading

$(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]
