    Is it possible to add error bars to a column chart using UI for ASP.NET AJAX? Haven't been able to find any information on this. Thanks.

    Hi Joe,

    Could you explain what you mean with "error bars"? If you want to color certain bars (e.g., ones with values over 100), you can do that via the ColorField property of the series. You can see that in action in the following demo: http://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/custombarcolor/defaultcs.aspx.

    The following article also shows several ways to show tresholds that can be used as indicators for errors: http://docs.telerik.com/devtools/aspnet-ajax/controls/htmlchart/how-to/plot-threshold-lines.

    Hi Marin.

    Here are two examples of error bars added to charts using Kendo UI. 

    http://demos.telerik.com/kendo-ui/line-charts/error-bars

    http://demos.telerik.com/kendo-ui/bar-charts/error-bars

    I would like to add error bars to a column chart using UI for ASP.NET AJAX to display upper and lower confidence intervals for the value represented by each column. This is a client requirement--not a box plot chart, candlestick chart, ranged column chart or anything else.

    I can accomplish this with an ASP.NET control (two series on same chart) but prefer to use Telerik RadHtmlChart control if possible.

    Thanks!

    Clarification: is there a way to configure my RadHtmlChart control to display error bars without using Kendo UI?

    Hi Joe,

    You can cast your vote for the this feature request in order to increase its priority: http://feedback.telerik.com/Project/108/Feedback/Details/126124-add-error-bars-in-radhtmlchart.

    RadHtmlChart is a server wrapepr for the Kendo chart, so once this gets implemented in it, you will still be using the Kendo Chart feature.

    In the meantime I can suggest you implement this chart by using the Kendo Chart widget rather than RadHtmlChart.
