Repro Steps:
1. Open URL: https://docs.telerik.com/devtools/aspnet-ajax/controls/chart/understanding-radchart-types/bar-charts page in Edge Browser.
2. Navigate the Graph under the Bar chart section.
3. Observe that Voice Access Numbers are not showing for bar graphs in reports.
Actual Results:
Voice Access Numbers are not showing for bar graphs.
Expected Results:
Voice Access Numbers should be showing for bar graphs.
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>

The charts starts to perform zooming when the user pans with one finger in touch devices.
Steps to reproduce:
1. Open the following demo in a touch device (or Chrome simulator)
https://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/pan-zoom/defaultcs.aspx
2. Start panning until the zooming issue occurs
Video: http://somup.com/cr6lo73b73
Problem appers with x-axis if you try to zoom.

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) {
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.
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).
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.
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.
Please refer to the ticket for more details.
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. https://docs.telerik.com/devtools/aspnet-ajax/controls/htmlchart/chart-types/line-chart
Hi, MissingValue set to Gap or Zero doesn't work in RadHtmlChart with ScatterLineSeries. Interpolation is done instead. <telerik:RadHtmlChart runat="server"> <PlotArea> <Series> <telerik:ScatterLineSeries Name="Test" DataFieldX="XValue" DataFieldY="YValue" MissingValues="Gap"> <SeriesItems> <telerik:ScatterSeriesItem X="1" Y="8" /> <telerik:ScatterSeriesItem X="2" Y="9" /> <telerik:ScatterSeriesItem X="3" Y="4" /> <telerik:ScatterSeriesItem X="4" Y="6" /> <telerik:ScatterSeriesItem X="5" Y="7" /> <telerik:ScatterSeriesItem X="8" Y="1" /> <telerik:ScatterSeriesItem X="9" Y="5" /> <telerik:ScatterSeriesItem X="10" Y="4" /> </SeriesItems> </telerik:ScatterLineSeries> </Series> </PlotArea> </telerik:RadHtmlChart> The workaround described in the following link doesn't work either : https://feedback.telerik.com/Project/108/Feedback/Details/44399-fix-the-functionality-of-the-missingvalue-property-when-set-to-gap-in-areaserie Can you please fix this bug ? Thanks and regards.
The contrast between the colors for the background and the text in the Tooltip of the Chart series is very low (dark background and black text). https://www.screencast.com/t/fhx6937j The problem is most obvious in the Outlook, Simple, Web20 and Sunset skins. Workaround would be setting the Color property for the ToolTipAppearance to White
