Perfect!!!

Thanks

Hi,

I am using a Columnline Chart. I want to use ChartText property which is present in the chart. I dont know how many values i will be getting in the graph, but for all the things, i want to add the Charttext property dynamically through the Codebehind file.

If it is possible please send me the sample code.

Hello,

I'm trying to create a composite chart to dsiplay both a column chart and a line chart similar to the attached image. I'm having trouble formatting the y and y2 axis and getting the the X Axis to format to "MM/dd/yyyy". Also the y Axes aren't extending far enough to show the Y2 data pionts. Heres the code that I have so far:

Dim columnLineChart As New UltraChart

columnLineChart.ChartType =ChartType.Composite

Dim area As New ChartArea()

columnLineChart.CompositeChart.ChartAreas.Add(area)

Dim xAxisColumn As New AxisItem(columnLineChart, AxisNumber.X_Axis)

Dim xAxisLine As New AxisItem(columnLineChart, AxisNumber.X_Axis)

xAxisColumn.DataType =AxisDataType.String

xAxisColumn.SetLabelAxisType = Layers.SetLabelAxisType.GroupBySeries

xAxisColumn.Labels.ItemFormat =AxisItemLabelFormat.ItemLabel

xAxisLine.DataType =AxisDataType.String

xAxisLine.SetLabelAxisType = Layers.SetLabelAxisType.ContinuousData

Dim yAxis As New AxisItem(columnLineChart, AxisNumber.Y_Axis)

yAxis.DataType =AxisDataType.Numeric

yAxis.TickmarkStyle =AxisTickStyle.Smart

yAxis.TickmarkInterval = 10

yAxis.NumericAxisType =NumericAxisType.Linear

yAxis.RangeType =AxisRangeType.Automatic

yAxis.Labels.ItemFormat =AxisItemLabelFormat.DataValue

Dim yAxis2 As New AxisItem(columnLineChart, AxisNumber.Y2_Axis)

yAxis2.DataType =AxisDataType.Numeric

yAxis2.Labels.ItemFormat =AxisItemLabelFormat.DataValue

yAxis2.TickmarkStyle =AxisTickStyle.Percentage

area.Axes.Add(xAxisColumn)

area.Axes.Add(xAxisLine)

area.Axes.Add(yAxis)

area.Axes.Add(yAxis2)

Dim seriesColumn As New NumericSeries()

seriesColumn.Data.DataSource = table

seriesColumn.Data.LabelColumn ="WeekEnd"

seriesColumn.Data.ValueColumn ="Evaluations"

Dim seriesLine As New NumericSeries()

seriesLine.Data.DataSource = table

seriesLine.Data.LabelColumn ="WeekEnd"

seriesLine.Data.ValueColumn ="Score"

columnLineChart.Series.AddRange({seriesLine, seriesColumn})

Dim columnLayer As New ChartLayerAppearance()

columnLayer.AxisX = xAxisColumn

columnLayer.AxisY = yAxis

columnLayer.ChartArea = area

columnLayer.ChartType =ChartType.ColumnChart

columnLayer.Series.Add(seriesColumn)

Dim LineLayer As New ChartLayerAppearance()

LineLayer.AxisX = xAxisLine

LineLayer.AxisY = yAxis2

LineLayer.ChartArea = area

LineLayer.ChartType =ChartType.LineChart

LineLayer.Series.Add(seriesLine)

columnLineChart.CompositeChart.ChartLayers.Add(columnLayer)

columnLineChart.CompositeChart.ChartLayers.Add(LineLayer)

columnLineChart.Border.Color =Color.LightGray

columnLineChart.Width = 1000

columnLineChart.Height = 500

columnLineChart.Axis.Y.TickmarkStyle =

AxisTickStyle.Smart

columnLineChart.Axis.Y.TickmarkInterval = 10

columnLineChart.Axis.Y.NumericAxisType =NumericAxisType.Linear

columnLineChart.Axis.Y.RangeType =

AxisRangeType.Automatic

columnLineChart.Axis.Y2.TickmarkStyle =AxisTickStyle.Percentage

ChartTextAppearance chartText = new ChartTextAppearance();
chartText.Column = chartText.Row = -2;
chartText.ItemFormatString = "<DATA_VALUE:0.##>";
chartText.Visible = true;
chart.ColumnLineChart.Column.ChartText.Add(chartText);
chart.ColumnLineChart.Line.ChartText.Add(chartText);
