在 MVC 应用程序中，我使用的是 Dotnet HighCharts。我可以在页面中呈现图表，但作为我的新手，一件事并不像预期的那样。我没有得到数据点（小弹出框提供有关图中某个点的详细信息）。我传递给图表的数据由 5000 条记录组成，但我没有得到每个点的数据点。这是我的图表的显示：
在 HighChart 站点，这是一个相同类型的演示，显示每条记录的数据点。
我的代码如下，请您帮助和指导我。我非常感谢您的时间、分享和帮助。
感谢期待。
下面的代码生成图表：
private Highcharts GetChart(List<CurrencyConversion> conversions, DateTime dateFrom, DateTime dateTo)
{
Highcharts chart = null;
string currencyFrom, currencyTo;
if (conversions != null && conversions.Count() > 0)
{
object[][] data = conversions.Select(c => new object[] { c.LastUpdatedDate, c.Rate }).ToArray();
currencyFrom = conversions.Select(c => c.CurrencyFrom).FirstOrDefault();
currencyTo = conversions.Select(c => c.CurrencyTo).FirstOrDefault();
chart = new Highcharts("chart")
.SetOptions(new GlobalOptions { Global = new Global { UseUTC = false } })
.InitChart(new Chart { ZoomType = ZoomTypes.X, SpacingRight = 20 })
.SetTitle(new Title { Text = "" })
.SetSubtitle(new Subtitle { Text = "Click and drag in the plot area to zoom in" })
.SetXAxis(new XAxis
{
Type = AxisTypes.Datetime,
MinRange = 3600000,
Title = new XAxisTitle { Text = "" }
})
.SetYAxis(new YAxis
{
Title = new YAxisTitle { Text = "Exchange rate" },
StartOnTick = false,
EndOnTick = false,
Min = 0.1
})
.SetTooltip(new Tooltip { Shared = true })
.SetLegend(new Legend { Enabled = false })
.SetPlotOptions(new PlotOptions
{
Area = new PlotOptionsArea
{
FillColor = new BackColorOrGradient(new Gradient
{
LinearGradient = new[] { 0, 0, 0, 300 },
Stops = new object[,] { { 0, "rgb(116, 116, 116)" }, { 1, Color.LightSkyBlue } }
}),
LineWidth = 1,
Marker = new PlotOptionsAreaMarker
{
Enabled = false,
States = new PlotOptionsAreaMarkerStates
{
Hover = new PlotOptionsAreaMarkerStatesHover
{
Enabled = true,
Radius = 5
}
}
},
Shadow = false,
States = new PlotOptionsAreaStates { Hover = new PlotOptionsAreaStatesHover { LineWidth = 1 } },
PointInterval = 24 * 3600 * 1000,
AllowPointSelect = true, CropThreshold=10
//PointStart = new PointStart(startDate)
}
})
.SetSeries(new Series
{
Type = ChartTypes.Area,
Name = string.Format("{0} to {1}", currencyFrom, currencyTo), //graphHeading,
Data = new Data(data),
});
}
return chart;
}
