Question

我正在使用来自外部xml文件的数据创建一个简单的行高图，但是我不能让它显示小数点，例如，xml返回25.6,25.1,25.9并且图表将该行放入25和工具提示显示25而不是25.6等。这是代码：

function chart1(start, end) {

var options = {
    chart: {
        renderTo: 'chart1',
        type: 'line'
    },
    colors: ['#D9CDB6'],
    title: {
        text: 'Data coming from A4 table'
    },
     tooltip:{
            formatter:function(){
            return Highcharts.numberFormat(this.y,2,',')
            }
        },
        dataLabels: {
enabled: true,
formatter: function () {
    return Highcharts.numberFormat(this.y,2);
}
}, 
xAxis: {
        labels: {
            enabled: false
        },
        categories: []
    },
    yAxis: {
        title: {
            text: 'Volts'
        },
        labels: {
       format: '{value:.2f}'}
    },

    series: []
};
// Load the data from the XML file 
$.get('chart1data.php?start=' + start + '&end=' + end, function(xml) {

    // Split the lines
    var $xml = $(xml);

    // push categories
    $xml.find('categories item').each(function(i, category) {
        options.xAxis.categories.push($(category).text());
    });

    // push series
    $xml.find('series').each(function(i, series) {
        var seriesOptions = {
            name: $(series).find('name').text(),
            data: []
        };

        // push data points
        $(series).find('data point').each(function(i, point) {
            seriesOptions.data.push(
                    parseInt($(point).text())
                    );
        });

        // add it to the options
        options.series.push(seriesOptions);
    });
    var chart = new Highcharts.Chart(options);
});
}

并且chart1data返回：

尝试改变，到。作为小数分隔符，但没有发生任感谢

Answer 1

解决了将parseInt（$（point）.text（））更改为parseFloat（$（point）.text（））

highcharts不显示来自xml的小数点
