我正在使用asp.net mvc3使用dotnet高图。在将多个系列添加到样条图表中,我面临问题。
此代码基本上每秒更新图表。
这项工作找到了一个数据系列。但是我需要添加多个数据系列。
请帮助我为此代码添加多个系列。
预先感谢
public ActionResult SplineUpdateEachSecond()
{
List<object> points = new List<object>(20);
DateTime now = DateTime.Now;
Random rand = new Random();
for (int i = -19; i <= 0; i++)
points.Add(new { X = now.AddSeconds(i), Y = rand.NextDouble() });
Highcharts chart = new Highcharts("chart")
.SetOptions(new GlobalOptions { Global = new Global { UseUTC = false } })
.InitChart(new Chart
{
DefaultSeriesType = ChartTypes.Spline,
MarginRight = 10,
Events = new ChartEvents
{
Load = "ChartEventsLoad"
}
})
.AddJavascripFunction("ChartEventsLoad",
@"// set up the updating of the chart each second
var series = this.series[0];
setInterval(function() {
var x = (new Date()).getTime(), // current time
y = Math.random();
series.addPoint([x, y], true, true);
}, 1000);")
.SetTitle(new Title { Text = "Live random data" })
.SetXAxis(new XAxis
{
Type = AxisTypes.Datetime,
TickPixelInterval = 150
})
.SetYAxis(new YAxis
{
Title = new YAxisTitle { Text = "Value" },
PlotLines = new[]
{
new YAxisPlotLines
{
Value = 0,
Width = 1,
Color = ColorTranslator.FromHtml("#808080")
}
}
})
.SetTooltip(new Tooltip { Formatter = "TooltipFormatter" })
.AddJavascripFunction("TooltipFormatter",
@"return '<b>'+ this.series.name +'</b><br/>'+
Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) +'<br/>'+
Highcharts.numberFormat(this.y, 2);")
.SetLegend(new Legend { Enabled = false })
.SetExporting(new Exporting { Enabled = false })
.SetSeries(new Series
{
Name = "Random data",
Data = new Data(points.ToArray())
});
return View(chart);
}
这里有示例。
假设,有一个类似于下面的返回系列的类:
public class ChartsData
{
//public static Series Hestavollane
//public static Series Voll
}
第一个系列:
public static Series Hestavollane = new Series
{
Name = "Hestavollane",
Data = new Data(new object[]
{
4.3, 5.1, 4.3, 5.2, 5.4, 4.7, 3.5, 4.1, 5.6, 7.4, 6.9, 7.1,
7.9, 7.9, 7.5, 6.7, 7.7, 7.7, 7.4, 7.0, 7.1, 5.8, 5.9, 7.4,
8.2, 8.5, 9.4, 8.1, 10.9, 10.4, 10.9, 12.4, 12.1, 9.5, 7.5,
7.1, 7.5, 8.1, 6.8, 3.4, 2.1, 1.9, 2.8, 2.9, 1.3, 4.4, 4.2,
3.0, 3.0
})
};
第二系列:
public static Series Voll = new Series
{
Name = "Voll",
Data = new Data(new object[]
{
0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.1, 0.0, 0.3, 0.0,
0.0, 0.4, 0.0, 0.1, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0,
0.0, 0.6, 1.2, 1.7, 0.7, 2.9, 4.1, 2.6, 3.7, 3.9, 1.7, 2.3,
3.0, 3.3, 4.8, 5.0, 4.8, 5.0, 3.2, 2.0, 0.9, 0.4, 0.3, 0.5, 0.4
})
};
应用于图表
.SetSeries(new[] { ChartsData.Hestavollane, ChartsData.Voll })
