Currently, the HighlightAppearance of the Series does not have a property that controls the InactiveOpacity:

As a temporary workaround, this can be set through the options in the OnKendoWidgetInitializing event:

<script>
    function OnKendoWidgetInitializing(sender, args) {
        var series = args.series[0]
        series.highlight = series.highlight || {};
        series.highlight.inactiveOpacity = 0.2
    }
</script>
<telerik:RadHtmlChart ID="RadHtmlChart5" runat="server" BorderColor="Fuchsia" BorderStyle="Solid" BorderWidth="1px">
    <ClientEvents OnKendoWidgetInitializing="OnKendoWidgetInitializing" />
    <PlotArea>

        <Series>
            <telerik:PieSeries StartAngle="90">
                <%-- This is how it should be configured after the feature request --%>
                <%--<HighlightAppearance InactiveOpacity="0.2" />--%>

                <SeriesItems>
                    <telerik:PieSeriesItem Name="Slice1" Y="60"></telerik:PieSeriesItem>
                    <telerik:PieSeriesItem Name="Slice2" Y="40"></telerik:PieSeriesItem>
                </SeriesItems>
            </telerik:PieSeries>
        </Series>
    </PlotArea>
</telerik:RadHtmlChart>

My objective is to compare product revenue over time. This I would like to achieve using data binding. I do not have information of product names or have the product names as columns. My data table structure is having three columns:

Date
Product Name
Revenue

This I should simply be able to achieve using data binding to a table with above three columns. 
In result I expect each of the Product Names to appear as independent series with revenues plotted on different dates.

A similar graph is displayed in the Line Chart documentation for RadHtmlChart.

I would like to request a new feature in legend of RadHtmlChart that provide a tool-tip for long names because when I add a long text in legends the size of pie-chart is reduced. 
Sample code for what I expect to be working :

<telerik:RadHtmlChart runat="server" ID="Chart" Height="400px" Width="400px">
<ClientEvents OnLoad="onChartLoad" />
function onChartLoad()
{
var chart = $find("Chart");
var widget = chart.get_kendoWidget();
widget.options.legend.tooltip = "#: dataItem.columnname #" //Feature Request in this line
widget.redraw();
}

For the time being the following events can be handled through the chartObject.

Select event is fired when the range of the selector from the navigator pane is changed.

JavaScript:

    <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
        <script>
            function pageLoad() {
                var chart = $find('<%=RadHtmlChart1.ClientID%>');
                chart._chartObject.bind("selectEnd", OnSelectEnd);
            }

            function OnSelectEnd(e) {
                alert("OnSelectEnd triggered: \nFrom: " + e.from + "\n To: " + e.to);
            }

        </script>
    </telerik:RadCodeBlock>
ASPX:

        <telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Layout="Stock" Width="800" Height="400"
            Transitions="true">
            <PlotArea>
                <XAxis Name="mainAxis" DataLabelsField="SellDate" Type="Date">

                    <telerik:ColumnSeries DataFieldY="SellQuantity">
                    </telerik:ColumnSeries>
                </Series>
            </PlotArea>
            <Navigator Visible="true">
                <XAxis Name="navAxis"></XAxis>
                <SelectionHint Visible="true" />
                <Series>
                    <telerik:AreaSeries DataFieldY="SellQuantity">

                </Series>
            </Navigator>
        </telerik:RadHtmlChart>

C#:

    protected void Page_Load(object sender, EventArgs e)
    {
        RadHtmlChart1.DataSource = GetData();
        RadHtmlChart1.DataBind();
    }

    protected DataTable GetData()
    {
        DataTable dt = new DataTable();

        dt.Columns.Add("ID", typeof(int));
        dt.Columns.Add("SellQuantity", typeof(int));
        dt.Columns.Add("SellDate", typeof(DateTime));

A good improvement in the RadHtmlChart would be to add MaxSize and MinSize properties for the series, which would allow the control the scaling of the bubble chart item. The property can be set through the chartObject:

        <script>
            function pageLoad() {
                var chart = $find("<%=BubbleChart.ClientID%>");
                chart.get_kendoWidget().options.series[0].minSize = 1;
                chart.get_kendoWidget().options.series[0].maxSize = 10;
                chart.get_kendoWidget().redraw();
            }
        </script>
        ASPX:
        <telerik:RadHtmlChart runat="server" ID="BubbleChart" Width="500" Height="400">
            <PlotArea>
                <Series>
                    <telerik:BubbleSeries>
                        <Appearance FillStyle-BackgroundColor="#6ab2c9">
                        </Appearance>
                        <SeriesItems>
                            <telerik:BubbleSeriesItem Size="1" X="5" Y="5500" />
                            <telerik:BubbleSeriesItem Size="5" X="14" Y="12200" />
                            <telerik:BubbleSeriesItem Size="15" X="20" Y="39000" />
                        </SeriesItems>
                    </telerik:BubbleSeries>
                </Series>
            </PlotArea>
        </telerik:RadHtmlChart>


More detailed information regarding these properties can be found in the API reference of the Kendo UI Chart here:

The chart's labels also look misaligned in rtl direction, so you can change only chart's direction to ltr with CSS:
	<style>
		.RadHtmlChart {
			direction: ltr;
		}
	</style>

		<div dir="rtl">
			some text
		<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server" Width="600" Height="400">
			<PlotArea>
				<Series>
					<telerik:ColumnSeries Name="Series 1">

							<telerik:CategorySeriesItem Y="30" />
							<telerik:CategorySeriesItem Y="10" />
							<telerik:CategorySeriesItem Y="20" />
						</SeriesItems>
					</telerik:ColumnSeries>
				</Series>
				<XAxis>
					<LabelsAppearance RotationAngle="33"></LabelsAppearance>

A visual example - http://i.stack.imgur.com/zRwlo.jpg

The feature will be useful for projects that need 508 compliance.

A boolean properties will also be useful: "EnabledTexturedFill", "EnableColorAndTexturedFill"

Would be nice to be able to supply an image for the series background on bar and column charts, this would enable infographic style option to charts, i.e. displaying data for countries the bar series can be repeating national flags.

For the time being you can choose either approach:

1) Set the min and max dates on the kendo widget:
ASPX:
		<script>
			function pageLoad() {
				var chart = $find("<%=RadHtmlChart1.ClientID%>");
				chart._chartObject.options.xAxis.min = new Date(2013, 04, 01);
				chart._chartObject.options.xAxis.max = new Date(2013, 05, 01);
				chart.repaint();
			}
		</script>
		<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="640px" Height="480px">
			<PlotArea>
				<Series>
					<telerik:ScatterLineSeries DataFieldY="SellQuantity" DataFieldX="SellDate">
						<LabelsAppearance DataFormatString="{1} cars sold on {0:m}">
						</LabelsAppearance>
						<TooltipsAppearance Color="White" DataFormatString="{1} cars sold on<br/>{0:D}" />
					</telerik:ScatterLineSeries>
				</Series>
				<XAxis BaseUnit="Days">
					<TitleAppearance Text="Sell Date">
					</TitleAppearance>
					<LabelsAppearance DataFormatString="d" RotationAngle="45">
					</LabelsAppearance>
					<MajorGridLines Color="#EFEFEF" Width="1"></MajorGridLines>
					<MinorGridLines Color="#F7F7F7" Width="1"></MinorGridLines>
				</XAxis>
				<YAxis>
					<TitleAppearance Text="Quantity">
					</TitleAppearance>
					<MajorGridLines Color="#EFEFEF" Width="1"></MajorGridLines>
					<MinorGridLines Color="#F7F7F7" Width="1"></MinorGridLines>
				</YAxis>
			</PlotArea>
			<ChartTitle Text="Sold Cars per Date">
			</ChartTitle>
		</telerik:RadHtmlChart>
C#:
	protected void Page_Load(object sender, EventArgs e)
	{
		RadHtmlChart1.DataSource = GetData();
		RadHtmlChart1.DataBind();
	}

	protected DataTable GetData()
	{
		DataTable dt = new DataTable();

		dt.Columns.Add("ID", typeof(int));
		dt.Columns.Add("SellQuantity", typeof(int));
		dt.Columns.Add("SellDate", typeof(DateTime));

		dt.Rows.Add(1, 2, new DateTime(2013, 05, 12));
		dt.Rows.Add(2, 5, new DateTime(2013, 05, 13));
		dt.Rows.Add(3, 6, new DateTime(2013, 05, 17));
		dt.Rows.Add(4, 4, new DateTime(2013, 05, 18));
		dt.Rows.Add(5, 7, new DateTime(2013, 05, 22));

		return dt;
	}

2) Set the JavaScript equivalent of min and max dates in the code behind like follows:
C#:
	protected void Page_Load(object sender, EventArgs e)
	{
		//Set min and max date for a datetime x-axis type
		RadHtmlChart1.PlotArea.XAxis.MinValue = ConvertToJavaScriptDateTime(new DateTime(2014, 02, 19));
		RadHtmlChart1.PlotArea.XAxis.MaxValue = ConvertToJavaScriptDateTime(new DateTime(2014, 04, 05));

		//Instantiate ScatterSeriesItem objects
		ScatterSeriesItem ssi1 = new ScatterSeriesItem();
		ScatterSeriesItem ssi2 = new ScatterSeriesItem();
		ScatterSeriesItem ssi3 = new ScatterSeriesItem();
		ScatterSeriesItem ssi4 = new ScatterSeriesItem();
		//Instantiate DateTime objects
		DateTime date1 = (new DateTime(2014, 03, 03, 0, 0, 0));
		DateTime date2 = (new DateTime(2014, 03, 10, 0, 0, 0));
		DateTime date3 = (new DateTime(2014, 03, 17, 0, 0, 0));
		DateTime date4 = (new DateTime(2014, 03, 24, 0, 0, 0));
		//Set the converted x values to the ScatterSeriesItem objects
		ssi1.X = ConvertToJavaScriptDateTime(date1);
		ssi2.X = ConvertToJavaScriptDateTime(date2);
		ssi3.X = ConvertToJavaScriptDateTime(date3);
		ssi4.X = ConvertToJavaScriptDateTime(date4);
		//Set the y values to the ScatterSeriesItem objects
		ssi1.Y = 3;
		ssi2.Y = 6;
		ssi3.Y = 5;
		ssi4.Y = 9;
		//Add the ScatterSeriesItem objects to the ScatterLineSeries
		(RadHtmlChart1.PlotArea.Series[0] as ScatterLineSeries).SeriesItems.Add(ssi1);
		(RadHtmlChart1.PlotArea.Series[0] as ScatterLineSeries).SeriesItems.Add(ssi2);
		(RadHtmlChart1.PlotArea.Series[0] as ScatterLineSeries).SeriesItems.Add(ssi3);
		(RadHtmlChart1.PlotArea.Series[0] as ScatterLineSeries).SeriesItems.Add(ssi4);
	}

	//A method that converts the .NET DateTime object to its JavaScript Date object representation
	protected decimal ConvertToJavaScriptDateTime(DateTime fromDate)
	{
		return (decimal)fromDate.Subtract(new DateTime(1970, 1, 1)).TotalMilliseconds;
	}
ASPX:
		<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="640px" Height="480px">
			<PlotArea>
				<Series>
					<telerik:ScatterLineSeries Name="Stock A">
						<LabelsAppearance>
							<ClientTemplate>
                        #= kendo.format(\'{0:d/MM/yyyy}\', new Date(value.x)) #,  #=kendo.format(\'{0:C0}\',value.y)#
							</ClientTemplate>
						</LabelsAppearance>
						<TooltipsAppearance Color="White">
							<ClientTemplate>
                        #= kendo.format(\'{0:d/MM/yyyy}\', new Date(value.x)) #,  #=kendo.format(\'{0:C0}\',value.y)#
							</ClientTemplate>
						</TooltipsAppearance>
					</telerik:ScatterLineSeries>
				</Series>
				<YAxis>
					<LabelsAppearance DataFormatString="C0"></LabelsAppearance>
					<TitleAppearance Text="Price"></TitleAppearance>
				</YAxis>
				<XAxis Type="Date" BaseUnit="Days">
					<TitleAppearance Text="Closing Date">
					</TitleAppearance>
					<LabelsAppearance DataFormatString="d">
					</LabelsAppearance>
				</XAxis>
			</PlotArea>
			<ChartTitle Text="Closing Stock Prices">

For the time being you can use the following workaround:
		<script>
			function OnLoad(sender, args) {
				var kendoWidget = $find('<%=RadHtmlChart1.ClientID%>').get_kendoWidget();
				kendoWidget.options.legend.reverse = true;
				kendoWidget.redraw();
			}
