为什么谷歌烛台图看起来很难看

Question

我正在尝试使用Google Chart API创建烛台图表。但是，无论我如何调整选项，图表看起来都很难看。我错过了吗？

if (data != null){
            var d = new google.visualization.DataTable();
            d.addColumn("date", "day");
            d.addColumn("number", "low");
            d.addColumn("number", "open");
            d.addColumn("number", "close");
            d.addColumn("number", "high");
            for(i=data.Time.length-100; i < data.Time.length; i++){
                var date = new Date(data.Time[i].Year, data.Time[i].Month, data.Time[i].Day);
                d.addRow([date, data.Low[i], data.Open[i], data.Close[i], data.High[i]]);
            }

        var options = {
            legend: 'none',
            width: 1200,
            height: 600,
            bar: {groupWidth: '100%'},
            candlestick: {
                hollowIsRising: true,
            }
        };

        var chart = new google.visualization.CandlestickChart(document.getElementById('divCharts'));
        chart.draw(d, options);

}

然而，如果我只是使用谷歌提供的示例并使用相同的选项，那么图表看起来就像预期的那样：

d = google.visualization.arrayToDataTable([
                                                         ['Mon', 20, 28, 38, 45],
                                                         ['Tue', 31, 38, 55, 66],
                                                         ['Wed', 50, 55, 77, 80],
                                                         ['Thu', 50, 77, 66, 77],
                                                         ['Fri', 15, 66, 22, 68]], true); // Treat first row as data as well.
