Radhtmlcharts in codebehind

i was able to create charts programatically

for barchart i have couple of issues
1. DataLabelsField not working
2. tooltip shows undefined if i use clienttemplate
3. legend does not show up

below is the sample code, i am using q2 2013 telerik dll

   Dim chart1 As New RadHtmlChart()
        chart1.ID = "ch1"
        chart1.Width = Unit.Pixel(240)
        chart1.Height = Unit.Pixel(240)

        Dim chartData As New BarSeries
        For Each dr As DataRow In dt.Rows
            Dim item As New SeriesItem
            item.Name = dr("col1")
            item.YValue = dr("col2")
            chartData.Items.Add(item)
            chart1.PlotArea.XAxis.DataLabelsField = dr("col1")
            
        Next


        chartData.DataFieldY = ycol
        chart1.PlotArea.XAxis.MinorGridLines.Visible = False
        chart1.PlotArea.YAxis.MinorGridLines.Visible = False
        chart1.ChartTitle.Text = charttitle
        chartData.LabelsAppearance.Visible = True
        chart1.PlotArea.Series.Add(chartData)
        chart1.Legend.Appearance.Visible = True

        chartData.TooltipsAppearance.ClientTemplate = "#=dataItem.col3#"

Hello,

Please find my comments and suggestions below:

 - DataLabelsField property and templates that has this structure "#=dataItem.dataSourceFieldName#" require a data bound chart. More details on data bound charts and using clients templates is available in the following resources:
  Templates related articles and demos:

• Overview
• Using ClientTemplates to Display HTML and Execute JavaScript
• HtmlChart - Client Templates for Series Labels and Tooltips

  Databinding related articles and demos:

• Binding a RadHtmlChart to a SqlDataSource
• HtmlChart - SqlDataSource

  - Creating items programmatically requires that you use the corresponding series classes. More
information on the matter is available in the Important Changes Regarding Series Declaration help article.

 

  - Legend consists of series names. Therefore you should set the Name property of each series.

Thanks Danail
datalabels, tooltip issue was of case sensitive dataitems which got resolved.
legend, i have a requirement
1. can legend take line breaks or display each series/category in new line
2. can piecharts have color separator between each item
3. can tooltip font/styles can be changed, i tried OnClientSeriesHovered to change style but it did not work as it was overriding.
4. can x-axis labels be listed as legend in columnseries instead of overlapping labels any samples?. i see that new telerik dll have smart labels
