jqwidgets图表不呈现任何数据

Question

我已导入 jqwidgets 脚本，但图表未呈现。我错过了什么？

Answer 1

为我生成图表的版本有点不同，我注意到高度和宽度绝对不是图表的属性。

它终于显示了对网站的攻击

我已包含所有代码，以便其他人可以看到我从哪里获取数据。我使用此代码生成 java：

@inject Walter.Web.FireWall.IFireWall _fireWall
@{
var data = _fireWall.Incidents.All()
                .Where(where => where.Reported > DateTime.Now.AddYears(-1))
                .GroupBy(groupOn => groupOn.Reported.Date)
                .Select(source => new
                {
                    date = source.Key,
                    active = source.Count(w => w.Expires > DateTime.Now),
                    expired = source.Count(w => w.Expires < DateTime.Now),
                }).OrderBy(order=>order.date)
                .ToArray();          
}

        $('#jqxIncidentChart').jqxChart(incidentChartSettings);
    });
</script>

它生成这个输出：
