I have been testing the highcharts on asp.net and they have worked well for me by defining them in the following way
In the .aspx:
<asp:Literal id="chrtMyChart" runat="server"></asp:Literal>
and in the .aspx.cs:
public void Grafica_Chart(int paciente, String Hora)
{
byte[] Datos = null;
byte[] Datos2 = null;
byte[] Datos3 = null;
List<int> graficoY = new List<int>();
Datos = selectAlarmas(paciente,Hora);
Datos2 = selectAlarmas2(paciente,Hora);
Datos3 = selectAlarmas3(paciente,Hora);
if (Datos == null)
{
Datos = new byte[1];
}
if (Datos2 == null)
{
Datos2 = new byte[1];
}
if (Datos3 == null)
{
Datos3 = new byte[1];
}
Object[] chartValues = new Object[Datos.Length];
Object[] chartValues2 = new Object[Datos2.Length];
Object[] chartValues3 = new Object[Datos3.Length];
for (int i = 0; i < Datos.Length; i++)
{
chartValues[i] = Datos[i];
}
for (int i = 0; i < Datos2.Length; i++)
{
chartValues2[i] = Datos2[i];
}
for (int i = 0; i < Datos3.Length; i++)
{
chartValues3[i] = Datos3[i];
}
// Declare the HighCharts object
DotNet.Highcharts.Highcharts chart = new DotNet.Highcharts.Highcharts("StockChart")
.InitChart(new Chart
{
Type = ChartTypes.Line,
ZoomType = ZoomTypes.X,
Width = 900,
Height = 300,
BackgroundColor = new BackColorOrGradient(System.Drawing.Color.Black),
})
.SetTitle(new Title
{
Text = ""
})
.SetPlotOptions(new PlotOptions
{
Line = new PlotOptionsLine
{
EnableMouseTracking = false,
Animation = new Animation(true) { },
Visible = false
},
})
.SetXAxis(new XAxis
{
Labels = new XAxisLabels
{
Enabled = false
}
})
.SetYAxis(new YAxis
{
Title = new YAxisTitle
{
Text = ""
},
Labels = new YAxisLabels
{
Enabled = false
}
})
.SetSeries(new[]
{
new Series
{
Name = "ECG1",
Data = new Data(chartValues), // Here we put the dbase data into the chart
Color = System.Drawing.Color.Lime
},
new Series
{
Name = "ECG2",
Data = new Data(chartValues2),
Color = System.Drawing.Color.DarkTurquoise
},
new Series
{
Name = "ECG3",
Data = new Data(chartValues3),
Color = System.Drawing.Color.Red
}
});
chrtMyChart.Text = chart.ToHtmlString(); // Let's visualize the chart into the webform.
}
and it works fine, but I want to see several graphics in the same ASP and they are not visualized by copying the code fragment and changing the identifier I would like to know how to do to be able to visualize about 10 graphics on the same page Thanks: D
