我的图表有卡路里与时间数据。每15分钟卡路里的价值。我想让酒吧更接近。我发布了一个数据样本，还有一个指向jsFiddle的链接。此外，是否可以在图表上显示整个24小时，并仅显示具有值的那些......

要使图表线更粗，您需要缩小系列中的间隙。

$("#chart").kendoChart({
  series: [ {
    gap: 0
  }]
});

以下是API参考 http://docs.telerik.com/kendo-ui/api/dataviz/chart#configuration-series.gap

他们还有一个如何动态执行此操作的教程。 http://demos.telerik.com/kendo-ui/bar-charts/gap-spacing

要仅显示数据时间，您必须将CategoryAxis定义为类型＆＃39;类别＆＃39;而不是类型＆＃39; date＆＃39;。当您将其定义为日期时，剑道将使用空白填充所有缺失的数据点，以使其看起来正确。为此，您可能需要将日期转换为可以作为类别排序的日期。

你可以让kendo自动聚合你的数据，这样它就会把时间合在一起。您可以通过将CaregoryAxis中的baseUnit设置为＆＃39; fit＆＃39;

来设置此项

$("#chart").kendoChart({
  categoryAxis: {
    baseUnit: "fit"
  }
});
