<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>

Workaround:

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