The lines can be similar to the ones in the box plot chart type - http://www.telerik.com/help/aspnet-ajax/htmlchart-types-box-plot-chart.html .

For the time being you can use transparent box plot series in order to simulate this. For example:

ASPX:

        <telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>
		<script>
			function pageLoad() {
				//Attach the legendItemClick event on pageLoad:
				var chart = $find("<%=RadHtmlChart1.ClientID%>")._chartObject.bind("legendItemClick", OnLegendClicked);
			}
			function OnLegendClicked(e) {
				if (e.seriesIndex >= 3) {
					var meanSeriesVisible = e.sender.options.series[3].visible;
					var medianSeriesVisible = e.sender.options.series[4].visible;

					if (meanSeriesVisible == medianSeriesVisible) {
						if (e.series.visible == false) {
							e.sender.options.series[5].visible = false;
						}
					}
					else {
						if (e.series.visible == false) {
							e.preventDefault();
							e.sender.options.series[3].visible = false;
							e.sender.options.series[4].visible = false;
							e.sender.options.series[5].visible = true;
							e.sender.options.transitions = false;
							e.sender.redraw();
						}
					}
				}
			}

I have a stacked bar RadHtmlChart that is created programmatically in the code behind.
When I create the chart, and set the width to Unit.Pixel(1500), it works fine, as shown in Working.png. However, when I change the value to Unit.Percentage(90), the chart is not rendered properly at all.

Any fixes/workarounds for this?

Seán


For the time being you must set percentage to the chart's wrapper. For example:
CSS:
	<style type="text/css">
		html, body, form {
			padding: 0;
			margin: 0;
			height: 100%;
			overflow: hidden;
		}

		.myChart {
			width: 100% !important;
			height: 100% !important;
		}
	</style>
ASPX:
		<div style="width: 30%; height: 40%; border: 1px solid green;">
			<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" CssClass="myChart" Width="600px" Height="400px">
				<PlotArea>
					<Series>
						<telerik:ColumnSeries Name="Product 1">
							<SeriesItems>
								<telerik:CategorySeriesItem Y="15000" />
								<telerik:CategorySeriesItem Y="23000" />
								<telerik:CategorySeriesItem Y="10000" />
							</SeriesItems>
						</telerik:ColumnSeries>
					</Series>
					<XAxis>
						<Items>
							<telerik:AxisItem LabelText="1" />
							<telerik:AxisItem LabelText="2" />
							<telerik:AxisItem LabelText="3" />
						</Items>
					</XAxis>
				</PlotArea>
				<ChartTitle Text="Product sales for 2011">
				</ChartTitle>
				<Legend>
					<Appearance Position="Bottom" />
				</Legend>
			</telerik:RadHtmlChart>
		</div>

A workaround is to use the ClientTemplate and change the strings manually with some JavaScript (http://www.telerik.com/help/aspnet-ajax/htmlchart-client-templates-for-tooltips-and-labels-execute-javascript-and-display-html.html), e.g.:
<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="400px" Height="400px">
	<PlotArea>
		<Series>
			<telerik:BarSeries>
			<LabelsAppearance>
			<ClientTemplate>
				#if (value > 0) {# $#=value# #} else {# -$#=value * -1# #} #
			</ClientTemplate>
			</LabelsAppearance>
				<SeriesItems>
					<telerik:CategorySeriesItem Y="20" />
					<telerik:CategorySeriesItem Y="10" />
					<telerik:CategorySeriesItem Y="-30" />
				</SeriesItems>
			</telerik:BarSeries>
		</Series>
	</PlotArea>

Series tooltips are not visible in a Stock chart when the same series is added programmatically in the plotarea and the navigator simultaneously.

The workaround is to:
1) Create different series for the plot area and the navigator.
2) Explicitly set the tooltips' visibility with JS like this:
        <script type="text/javascript">
            function pageLoad() {
                var chart = $find("Chart");
                var series = chart._chartObject.options.series[0];
                series.tooltip.visible = true;
                //repaint the chart to apply the changes
                chart.repaint();
            }
        </script>

The CSS styles of the selection hint of the navigator in HtmlChart are not applied correctly in a data navigation scenario.

The workaround is to override the styles that you need like this:
        .k-navigator-hint .k-tooltip {
            border: 2px solid red !important;
            color: #000 !important;
        }

Under the standard definition of data format strings, range scaling can be applied (i.e. divide by 1000) using , prefixing the implied or explicit decimal place.
e.g. DataFormatString="{0:#,#,}" will display 3000000 as 3,000

This works on RadPivotGrid correctly, but RadHTMLChart does not work either on data labels, axis labels, or pretty much anywhere else. Apparently a problem with kendo.format(), which does not do this as per documentation for DataFormatString

N.B. This is commonly used in finance presentations to globally present in $thousands.

When data-bound categorical series has zeros in the x-axis labels they are parsed and the zeros disappear. For example:
ASPX:

            <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
            <telerik:RadHtmlChart runat="server" ID="Radhtmlchart1">
                <PlotArea>
                    <Series>
                        <telerik:ColumnSeries DataFieldY="Score1"></telerik:ColumnSeries>
                   </Series>

                   <XAxis DataLabelsField="Student">
                    </XAxis>
                </PlotArea>
            </telerik:RadHtmlChart>

C#:

    protected void Page_Load(object sender, EventArgs e)
    {
        Radhtmlchart1.DataSource = GetData();
        Radhtmlchart1.DataBind();
    }
    protected DataTable GetData()
    {
        DataTable table = new DataTable();

        table.Columns.Add("Student", typeof(string));
        table.Columns.Add("Score1", typeof(int));

        table.Rows.Add(new object[] { "0806014562", 40 });
        table.Rows.Add(new object[] { "0806014562", 50 });
        table.Rows.Add(new object[] { "0806014562", 70 });
        return table;
    }
Workarounds:
1) Use format string to add the desired missing zeros when parsed.

<LabelsAppearance DataFormatString="0{0}"></LabelsAppearance>

2) Add items programmatically

    protected void Page_Load(object sender, EventArgs e)
    {
        Radhtmlchart1.DataSource = GetData();
        Radhtmlchart1.DataBind();

        DataTable currDT = GetData();
        for (int i = 0; i < currDT.Rows.Count; i++)
        {
            AxisItem currItem = new AxisItem(currDT.Rows[i]["Student"].ToString());
            Radhtmlchart1.PlotArea.XAxis.Items.Add(currItem);
        }
    }

Was hoping for the functionality where the difference area between lines could be colored accordingly.

example: htmlchart with 3 lines 1:+standard 2:-standard and 3:Actual value. If the Actual value line is below the -standard, the difference area should be colored red. In case it crosses the +standard it should be green.

Likely the Actual value line would be an Area-serie but that aside.

For the time being the property can be set through the kendoWidget:
$find('chartID').get_kendoWidget().options.panes[1].height = 60;
$find('chartID').get_kendoWidget().redraw();

The property (http://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart#configuration-categoryAxis.maxDateGroups) can be set through the kendoWidget:
JavaScript:

        <script>
            function OnLoad(args) {
                var kendoWidget = args.get_kendoWidget();
                kendoWidget.options.categoryAxis.maxDateGroups = 8;
                kendoWidget.options.categoryAxis.baseUnit = 'fit';
                kendoWidget.redraw();
            }
        </script>

ASPX:

        <telerik:RadHtmlChart runat="server" ID="RadHtmlChart2" Width="640px" Height="480px">
            <ClientEvents OnLoad="OnLoad" />
