Release R1 2020 SP1
Some HtmlChart appearance properties are not fully applied in R1 2020 (e.g. XAxis.MajorGridlines="false", ChartTitle.Appearance.TextStyle.Font, etc.)
 
Temporary workaround:
        <script>
            var datavizThemes = kendo.dataviz.ui.themes || {};
            Telerik.Web.UI.RadHtmlChart.prototype.applyTheme = function () {
                var that = this,
                 kendoWidget = that.get_kendoWidget(),
                 themeName = kendoWidget.options.theme,
                 theme = datavizThemes[themeName];
                if (theme && theme.chart) {
                    kendoWidget.setOptions(that._getTheme());
                }
            }
        </script>

The XAxis.MajorGridLines of the chart YAxis are always visible as of 2020.1.114
 
Code to reproduce the issue:
<telerik:RadHtmlChart ID="RequestsMonthChart" runat="server" Height="500">
    <ClientEvents OnLoad="chartLoad" />
    <PlotArea>
        <Series>
            <telerik:ColumnSeries Name="Series 1">
                <SeriesItems>
                    <telerik:CategorySeriesItem Y="30" />
                    <telerik:CategorySeriesItem Y="10" />
                    <telerik:CategorySeriesItem Y="20" />
                </SeriesItems>
            </telerik:ColumnSeries>
        </Series>
        <XAxis Name="Year" DataLabelsField="Month">
            <LabelsAppearance RotationAngle="-35" />
            <MajorGridLines Visible="false" />
            <MinorGridLines Visible="false" />
            <Items>
                <telerik:AxisItem LabelText="Item 1" />
                <telerik:AxisItem LabelText="Item 2" />
                <telerik:AxisItem LabelText="Item 3" />
            </Items>
        </XAxis>
        <YAxis>
            <MajorGridLines Visible="false" />
            <MinorGridLines Visible="false" />
        </YAxis>
    </PlotArea>
    <Legend>

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.

Code that reproduces the issue:

<telerik:RadHtmlChart runat="server" ID="RadHtmlChartColumnGender" Transitions="true" Width="150" Height="300">
			<PlotArea>
				<Series>
					<telerik:ColumnSeries Name="Male" Stacked="true" StackType="Stack100">
						<SeriesItems>
							<telerik:CategorySeriesItem Y="69" />
						</SeriesItems>
					</telerik:ColumnSeries>
					<telerik:ColumnSeries Name="Female" Stacked="true" StackType="Stack100">
						<SeriesItems>
							<telerik:CategorySeriesItem Y="3" />
						</SeriesItems>
					</telerik:ColumnSeries>
				</Series>
				<YAxis NarrowRange="false"></YAxis>
			</PlotArea>

		</telerik:RadHtmlChart>

Workaround:

		<script>
			function pageLoad() {
				var kendoChart = $find("RadHtmlChartColumnGender").get_kendoWidget();
				var valueAxis = kendoChart.options.valueAxis;
				valueAxis.narrowRange = false;
				$find("RadHtmlChartColumnGender").setOptions({valueAxis: valueAxis});
			}
		</script>

If you set in code behind CharTitle with simple Quote like 
RadChart1.ChartTitle.Text = "Présences sur l'année sélectionnée";
you obtain a blank space chart (nothing display)

you have to set for running
RadChart1.ChartTitle.Text = "Présences sur l&#039;année sélectionnée";

When you configure RadHtmlChart's YAxis with NarrowRange set to true, the setting is not serialized and as a result, not applied.
You can avoid it by setting the narrowRange on the client-side:

		<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="250px" Height="300px">
			<ClientEvents OnLoad="chartLoad" />
			...
		</telerik:RadHtmlChart>
		<script>
			function chartLoad(){
				var chart = $telerik.$("#RadHtmlChart1").data("kendoChart");
				chart.options.valueAxis.narrowRange = true;
			}
		</script>

				$find("RadHtmlChart2").get_kendoWidget().setOptions({
					legend: {
						position: "top",
						width: 162,
						height: 88,
						orientation: "vertical"
					}
				})
			}
		</script>
		<telerik:RadHtmlChart ID="RadHtmlChart2" runat="server" Width="350" Height="350">
			<ClientEvents OnLoad="chartLoad" />

 Workaround use padding instead of margin:
		<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server"  Width="600px" Height="400px">
			<PlotArea>
				<Series>
					<telerik:ColumnSeries Name="Product 1">
						<SeriesItems>
							<telerik:CategorySeriesItem Y="15000" />
							<telerik:CategorySeriesItem Y="-4000" />
							<telerik:CategorySeriesItem Y="10000" />
						</SeriesItems>
					</telerik:ColumnSeries>
				</Series>
				<XAxis>
					<LabelsAppearance RotationAngle="45">
						<TextStyle Padding="135 0 0 0" />
					</LabelsAppearance>
					<Items>
						<telerik:AxisItem LabelText="item1" />
						<telerik:AxisItem LabelText="item2" />
						<telerik:AxisItem LabelText="item3" />
					</Items>
				</XAxis>

For the time being you can use the following JavaScript workaround:

		<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server" Width="600" Height="300">
			<PlotArea>
				<Series>
					<telerik:LineSeries Name="series 1">

							<telerik:CategorySeriesItem Y="20" />
						</SeriesItems>
					</telerik:LineSeries>
				</Series>
				<XAxis MinValue="1">
				</XAxis>
			</PlotArea>
		</telerik:RadHtmlChart>
		<script>

                       //JavaScript workaround

			function isNumber(val) {
				return typeof val === "number" && !isNaN(val);
			}


			var dataviz = kendo.dataviz,
				inArray = dataviz.inArray,
				deepExtend = kendo.deepExtend,
				math = Math,
				AREA = "area",
				VERTICAL_AREA = "verticalArea",
				VERTICAL_LINE = "verticalLine",
				LINE = "line";

			kendo.dataviz.CategoricalPlotArea.fn.filterSeries = function (currentSeries, categoryAxis) {
				var range = categoryAxis.totalRangeIndices();
				var justified = categoryAxis.options.justified;
				var outOfRangePoints = inArray(currentSeries.type, [LINE, VERTICAL_LINE, AREA, VERTICAL_AREA]);
				var categoryIx;

				range.min = isNumber(categoryAxis.options.min) ? math.floor(range.min) : 0;
				range.max = isNumber(categoryAxis.options.max) ? (justified ? math.floor(range.max) + 1 : math.ceil(range.max)) : currentSeries.data.length;

				currentSeries = deepExtend({}, currentSeries);

				if (outOfRangePoints) {
					var minCategory = range.min - 1;
					var srcCategories = categoryAxis.options.srcCategories || [];
					if (minCategory >= 0 && minCategory < currentSeries.data.length) {
						categoryIx = minCategory;
						currentSeries._outOfRangeMinPoint = {
							item: currentSeries.data[categoryIx],
							category: srcCategories[categoryIx],

For the time being the reversed properties can be set through the kendo widget:
		<script>
			function pageLoad(sender, args) {

				var radarChart = $find('<%=RadarLineChart.ClientID%>').get_kendoWidget();
				var polarChart = $find('<%=PolarAreaChart.ClientID%>').get_kendoWidget();


				radarChart.options.valueAxis.reverse = true;
				polarChart.options.yAxis.reverse = true;


				radarChart.options.categoryAxis.reverse = true;
				polarChart.options.xAxis.reverse = true;

				radarChart.redraw();
				polarChart.redraw();
			}
		</script>

		<telerik:RadHtmlChart runat="server" ID="RadarLineChart" Width="345" Height="345">
			<PlotArea>
