The event should be similar to OnClientSeriesClicked event. It should expose information about the clicked series.

The property will specify the client-side event handler that is executed when the RadHtmlChart is initialized on the client and will be called after chart's transitions' animation.

For the time being the properties can be set through the chartObject. For example:

ASPX:

        <script>
            function pageLoad() {
                var chart = $find("<%=RadHtmlChart1.ClientID%>");
                chart._chartObject.options.valueAxis.max = 100;
                chart._chartObject.options.valueAxis.min = 10;
                chart.repaint();
            }
        </script>
        <telerik:RadHtmlChart ID="RadHtmlChart1" runat="server">
            <PlotArea>
                <Series>
                    <telerik:RadarColumnSeries DataFieldY="yValues">
                    </telerik:RadarColumnSeries>
                </Series>
                <XAxis DataLabelsField="xValues"></XAxis>
                <YAxis MinValue="10" MaxValue="100"></YAxis>
            </PlotArea>
        </telerik:RadHtmlChart>

C#:

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

Add the ability to click the legend's items in a similar way like the series 'items. For the time being the following workaround can be used:
JavaScript:

			var chart = $find("<%=RadHtmlChart1.ClientID%>")._chartObject.bind("legendItemClick", OnLegendClicked);
		}
                //The following function toggles the visibility of the clicked series from the legend
		function OnLegendClicked(e) {
			//Get a reference to the chart and the target axis
			var chart = e.sender;
			var targetAxisName = e.series.axis;
			var numValueAxes = chart.options.valueAxis.length;
			//Iterate through the y-axes and toggle the visibility of the axis that corresponds to the clicked series from the legend
			for (var i = 0; i < numValueAxes; i++) {
				var currValueAxisName = chart.options.valueAxis[i].name;
				if (currValueAxisName == targetAxisName) {
					chart.options.valueAxis[i].visible = !chart.options.valueAxis[i].visible;
				}
			}
		}

For the time being series can be stacked through the chartObject. For example:

				chart._chartObject.options.seriesDefaults.stack = true;

			}
		</script>

					<telerik:AreaSeries Name="Sales" MissingValues="Gap">

				chart.repaint();

Similar to the feature in RadChart - http://demos.telerik.com/aspnet-ajax/chart/examples/newfeatures/logarithmicaxis/defaultcs.aspx. 
For the time being the following workaround can be used:
ASPX:
		<script>
			function pageLoad() {
				var chart = $find("<%=RadHtmlChart1.ClientID%>");
				chart._chartObject.options.valueAxis.type = "log";
				chart.repaint();
			}

				<YAxis></YAxis>
				<Series>
					<telerik:ColumnSeries>
					</telerik:ColumnSeries>
				</Series>
			</PlotArea>
		</telerik:RadHtmlChart>
C#:
	protected void Page_Load(object sender, EventArgs e)
	{
		double[] yValues = new double[] { 0.01, 0.05, 0.11, 2, 2.5, 10, 30 };
		for (int i = 0; i < yValues.Length; i++)
		{
			CategorySeriesItem csi1 = new CategorySeriesItem() { Y = (decimal)yValues[i] };
			(RadHtmlChart1.PlotArea.Series[0] as ColumnSeries).SeriesItems.Add(csi1);
		}
	}

When a pie chart is rendered with large labels they may be clipped because the pie chart is not sized correctly.  When the legend is enabled the pie chart sizes correctly to handle long labels.

Your html charts are coming along beautifully - Just want more! Particularly a Spline chart - ideally to add as option for combination charts.  This could also work as a Pareto chart.

Currently MinValue and MaxValue properties of the Axes accepts only decimal, so that when the axes are of date type, Min and Max dates cannot be set.

The workaround is to obtain the min and max values from the datasource field used for populating XAxis labels and set these values explicitly to the XAxis through the chartObject. For example:
<script type="text/javascript">
    function pageLoad() {
        //Get reference to the chart
        var chart = $find("<%=RadHtmlChart1.ClientID%>");
  
        //Obtain charts datasource
        var currDataSource = eval(chart.get_dataSourceJSON());
  
         //Get minValue for the datasource field used for populating XAxis Labels. In this example the field is named myDataSourceField
        var minValue = currDataSource[0].myDataSourceField;
  
        //Get maxValue for the datasource field used for populating XAxis Labels. In this example the field is named myDataSourceField
        var maxValue = currDataSource[currDataSource.length - 1].myDataSourceField;
  
        //Reference the chartObject's min and max properties
        chart._chartObject.options.xAxis.min = minValue;
        chart._chartObject.options.xAxis.max = maxValue;
  
        //Repaint the chart
        chart.repaint();
    }

The property for each series could be RenderInPlotArea=true|false
It will control whether the series will be rendered in the plot area, if set to false the series name will still be present in the legend, but grayed out, as if the end user has clicked it already to hide the series in the browser. This will give the developer programmatic contol over the initial state of the chart that the end user can modify later.
For the time being the following workaround can be used:
JavaScript:
	<script>
		function pageLoad() {
			var chart = $find("<%=RadHtmlChart1.ClientID%>");
			chart._chartObject.options.series[0].visible = false;
			chart.repaint();
