" a is undefined " javaScript error in Line Chart
Hi All.
I make line Chart and after I add it in Items collection of a window and returning it as a result for my CreateLineChart Direct method Call.
The Code is here.
Any help or recommendation is appreciated in advance.
Code:
public static Window CreateLineChart(string chartID, string XAxeTitle, string YAxeTitle, string XAxeField, string YAxeField, int chartWidth, int chartHeight, string dataLoadURL, string entityID)
{
var dt = new DataTable();
SqlConnection cn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["KSPDBS"].ConnectionString);
SqlDataAdapter da = new SqlDataAdapter("Select * from ViwPDEntityItemLanguageTitles where EntityID=" + entityID + " Order By PresentationSequenceNo", cn);
da.Fill(dt);
var myStore = CreateStore(dt, "s1", "ID", dataLoadURL, null, "ID", 20, true);
Chart myChart = new Chart()
{
ID = "Chrt1",
StyleSpec = "background:#fff;",
Animate = true,
Shadow = true,
StandardTheme = StandardChartTheme.Category1,
LegendConfig = new ChartLegend()
{
Position = LegendPosition.Right,
}
};
NumericAxis myNumAxe = new NumericAxis()
{
Fields = new[] { YAxeField },
Title = YAxeTitle,
Minimum = 0,
MinorTickSteps = 1,
GridConfig = new AxisGrid()
{
Odd = new SpriteAttributes()
{
Opacity = 1,
Fill = "#ddd",
Stroke = "#bbb",
StrokeWidth = 0.5
}
}
};
myChart.Axes.Add(myNumAxe);
CategoryAxis ctgryAxe = new CategoryAxis()
{
Position = Position.Bottom,
Fields = new[] { XAxeField},
Title = XAxeTitle,
};
myChart.Axes.Add(ctgryAxe);
var linSer1 = new LineSeries()
{
Axis = Position.Left,
XField = new[] { XAxeField},
YField = new[] { YAxeField },
HighlightConfig = new SpriteAttributes()
{
Size = 7,
Radius = 7
},
MarkerConfig = new SpriteAttributes()
{
Type = SpriteType.Cross,
Size = 4,
Radius = 4,
StrokeWidth = 0
}
};
var linSer2 = new LineSeries()
{
Axis = Position.Left,
XField = new[] { XAxeField },
YField = new[] { YAxeField },
HighlightConfig = new SpriteAttributes()
{
Size = 7,
Radius = 7
},
MarkerConfig = new SpriteAttributes()
{
Type = SpriteType.Cross,
Size = 4,
Radius = 4,
StrokeWidth = 0
},
Smooth = 3
};
myChart.Series.Add(linSer1);
myChart.Series.Add(linSer2);
myChart.Height = chartHeight - 50;
myChart.Width = chartWidth - 50;
Window myWin = new Window()
{
ID = "w11",
Width = chartWidth,
Height = chartHeight,
Layout = "fit"
};
myChart.Render();
myWin.Items.Add(myChart);
return myWin;
}
