For the time being the property can be set on the client through the chartObject. For example:
JavaScript:
	<script>
		function pageLoad() {
			var chart = $find("<%=RadHtmlChart1.ClientID%>");
			chart._chartObject.options.series[0].highlight = {
				markers: {
					visible: true
				}
			}
			chart.repaint();
		}
	</script>
ASPX:
		<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server" Width="600" Height="400">
			<PlotArea>
				<Series>
					<telerik:LineSeries>
						<MarkersAppearance Visible="false" />
						<SeriesItems>
							<telerik:CategorySeriesItem Y="30" />
							<telerik:CategorySeriesItem Y="10" />

I have an htmlchart using a scatter series and a radgrid, on the grid row hover event I call the below javascript function to show the relevant tooltip for the plotted point matching the id of the grid row.

        function showToolTip(eventArgs, chart, plotXvalue, plotYvalue) {
            var chart = $telerik.findControl(document, chart);
            var widget = chart.get_kendoWidget();

            widget.showTooltip(function (point) {
                var gridID = eventArgs.getDataKeyValue("Id");
                var key = "ID";

                var mypoint = point.value.x == eventArgs.getDataKeyValue(plotXvalue) && point.value.y == eventArgs.getDataKeyValue(plotYvalue) && point.dataItem[key] == gridID;

                if (!mypoint) {
                    widget.hideTooltip();
                }
                return mypoint;
            })
        };

 

This all works well, however I would like to also highlight the plotted point that the tooltip relates to, the same effect as the mouse over on the point within the chart.

Currenlty Series like Bubble, Bar, Column, Donut, Pie and Candlestick do not expose any appearance properties for the Series border. Expose appearance border properties like width, dashtype, color and opacity.

Temporary workaround for managing the border appearance:
Javascript:
	<script language="javascript">
		function pageLoad() {
			var chart = $find("RadHtmlChart1");
			chart._chartObject.options.series[0].border = {
				width: 2,
				color: "black",
				dashType: "dash",
				opacity: 0.2
			}
			chart.repaint();
		}
	</script>

	<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server" Width="600" Height="400">

				<telerik:ColumnSeries>

The functionality is currently exposed only by the x-axis of the sparkliens. It would be a good idea to be exposed by the other series types as well.

For the time being you can configure the cross hair through the kendo widget:
<script>
			function pageLoad() {
				$find('RadHtmlChart1').get_kendoWidget().setOptions({categoryAxis:{crosshair:{ color: "green", width: 2, visible: true}}});
			}

Update data values using drag and drop directly from the chart, something like this:

https://forio.com/app/powersim/powerwall/energy_consumption_details.html

A lot of customers would have this functionality without changing the HTMLChart controls.

Right now we do not have a way to show some tooltips over Axis Labels
This is useful when we have big names for Axis Labels, we can put some short cut names be default and then show full name over tool tip.

We can use Series tooltip, but it looks ugly for stacked series when you have 4 to 5 series

Label position dynamic. I'm currently using "InsideBase", but if those values are so small it's not very visible, so i'd like place those on the outside end.

Hello, 

 

I would like to highlight a GridLine based on a Labelled item when I have implemented skip in the HTML Chart. 

 

Essentially, I have a series of days and would like to step the labels on a weekly basis. At each step I would like to highlight the GridLine associated with the label.

We want the Kendo chart widget (RadHtmlChart actually) to blend in with the webpage we use it in. In this page, we use font-weight 300. Since there is no way to specify the font-weight in the chart, we have had to use a hack to specify it:

 

            function chartLoad(chart, args) {
                chart.get_kendoWidget().setOptions({ title: { font: "20px sans-serif; font-weight: 300" }});
            }

 

This is not only a clumpsy hack, but it also make use of a custom skin impossible (for setting the font).
