Question

以下是我正在使用的格式化程序。

 Tooltip tooltip = new Tooltip();
 tooltip.setxDateFormat("MMM dd, YYYY");
 tooltip.setFormatter("function()  { var d = new Date(this.x);" + "return " + "'<b>'+this.series.name +'</b><br/>"
                + "<strong>Value :</strong> '+ this.y +'<br/>" + "<strong>Start Date :</strong> '+ this.x; " + "}");

 chartConfig.setTooltip(tooltip);

如何：

1）带有两位小数的圆值

2）使用日期格式，如2016年11月30日

请帮助。

Vaadin Charts在客户端使用Highcharts，这意味着您可以使用Highcharts JS API进行格式化，以下调用应该有效：
