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

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>

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> </PlotArea> </telerik:RadHtmlChart>

I have a stacked bar RadHtmlChart that is created programmatically in the code behind.
When I create the chart, and set the width to Unit.Pixel(1500), it works fine, as shown in Working.png. However, when I change the value to Unit.Percentage(90), the chart is not rendered properly at all.
Any fixes/workarounds for this?
Seán
For the time being you must set percentage to the chart's wrapper. For example:
CSS:
<style type="text/css">
html, body, form {
padding: 0;
margin: 0;
height: 100%;
overflow: hidden;
}
.myChart {
width: 100% !important;
height: 100% !important;
}
</style>
ASPX:
<div style="width: 30%; height: 40%; border: 1px solid green;">
<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" CssClass="myChart" Width="600px" Height="400px">
<PlotArea>
<Series>
<telerik:ColumnSeries Name="Product 1">
<SeriesItems>
<telerik:CategorySeriesItem Y="15000" />
<telerik:CategorySeriesItem Y="23000" />
<telerik:CategorySeriesItem Y="10000" />
</SeriesItems>
</telerik:ColumnSeries>
</Series>
<XAxis>
<Items>
<telerik:AxisItem LabelText="1" />
<telerik:AxisItem LabelText="2" />
<telerik:AxisItem LabelText="3" />
</Items>
</XAxis>
</PlotArea>
<ChartTitle Text="Product sales for 2011">
</ChartTitle>
<Legend>
<Appearance Position="Bottom" />
</Legend>
</telerik:RadHtmlChart>
</div>

For the time being you can resize the chart with set_width/set_height methods. For example:
<head runat="server">
<title></title>
<style>
.RadHtmlChart.k-chart, table {
width: 100%;
height: 100%;
}
td {
border: 1px solid green;
width: 60%;
height: 60%;
overflow:hidden;
}
html, body, form {
height: 100%;
overflow: hidden;
margin: 0;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>
<script>
function resizedw() {
// Haven't resized in 100ms!
var donut = $find("<%=DonutChart.ClientID%>");
var radar = $find("<%=RadarAreaChart.ClientID%>");
var docDimensions = $telerik.getBounds(document.body);
resizeChart(donut, docDimensions);
resizeChart(radar, docDimensions);
}
function resizeChart(chart, docDimensions) {
var chartDimensions = $telerik.getBounds(chart.get_element().parentElement);
chart.set_width("'" + (chartDimensions.width / docDimensions.width) + "%'");
chart.set_height(("'" + chartDimensions.height / docDimensions.height) + "'%");
}
var doit;
window.onresize = function () {
clearTimeout(doit);
doit = setTimeout(resizedw, 1000);
};
</script>

When you do a stacked HTMLChart (e.g. columns), the legend appears in the opposite order to the data series being stacked, which looks very unprofessional.

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'année sélectionnée";

Temporary workaround:
<script>

Telerik.Web.UI.RadHtmlChart.prototype.applyTheme = function () {
var that = this,
kendoWidget = that.get_kendoWidget(),

theme = datavizThemes[themeName];
if (theme && theme.chart) {
kendoWidget.setOptions(that._getTheme());
