1. Add method CategoricalErrorBarsBuilder.Field(string) that will indicate the name of the field containing the value for the error bar. This value would be a relative difference (not absolute high/low). There is a "Fields(string,string)" method but "Field(string)" for difference value is missing. 2. Provide way to render half (top or bottom) of error bar. For example, if only CategoricalErrorBarsBuilder.HighField(string) is assigned, then render top half of error bar. Or maybe some other setting. Often it is desirable to show only the side of the error bar that is above (or below, if the bar represents a negative value) the bar marker so that the other half is not rendered within the bar marker.

I would like to have an option to set an interval for refreshing the data in my chart (or any other control that uses a datasource). At this moment, I need to use the jQuery setInterval function to refresh the chart, but when using a dynamic range of controls, I don't want to write a refresh for every control on my page.
This can be done in two ways. First, a parameter in the wrapper that takes an int as value (for instance 5000 for 5 seconds). Second, an event that hooks into a JavaScript function, passing the id and type of the control. The first option is absolutely preferred (as shown in the code on line 10).
If you're declining this request, please advise on the best practice to handle this situation with regard to dynamic dashboards.
### Bug report
The legend items cannot be configured in the SeriesDefaults() configuration of the Pie Chart.
### Reproduction of the problem
1) Create a Pie Chart with a visible legend.
2) Add the SeriesDefaults() configuration and try to add the LegendItem() option to set the type of the legend items.
.SeriesDefaults(seriesDefaults =>
{
seriesDefaults
.Pie();
.LegendItem(x => x
.Type("line")
.Line(y => y.DashType(ChartDashType.Solid)));
})The Legenditem() option is available for Telerik UI for ASP.NET Core Pie Chart.
### Expected/desired behavior
The legend items of the Pie Chart must be configurable through the SeriesDefaults() option.
### Environment
* **Telerik UI for ASP.NET MVC version: 2024.1.319
* **Browser: [all]
Hello,
I noticed that the date format from my current kendo culture (fr-FR) is not applied properly for Weeks and Days units on xAxis labels of a chart with date axis.
I had to set the property DateFormats for Weeks and Days of my XAxis Labels to force the format (other units work fine) :
@(Html.Kendo.Chart(Of Models.DataViewModel).
Name("chart").
Title(typeMesure.GetDescription()).
DataSource(Sub(dataSource)
dataSource.Read(Sub(read)
read.Type(HttpVerbs.Get).Action("GetData","Data"))
End Sub).
Sort(Sub(sort) sort.Add(Function(m) m.Dt).Ascending())
End Sub).
Series(Sub(series) series.
ScatterLine(Function(m) m.Dt, Function(m) m.Value).
Markers(False).
MissingValues(ChartScatterLineMissingValues.Gap).
Color("#cb1d39").
Tooltip(Sub(tooltip)
tooltip.Visible(True).
Template("Date : #= kendo.toString(value.x, 'dd/MM/yyyy HH:mm') # <br/>Valeur : #= kendo.toString(value.y, 'n3') #")
End Sub)).
XAxis(Sub(xAxis) xAxis.Date().
Min(Model.DateDebut).
Max(Model.DateFin).
Labels(Sub(labels) labels.DateFormats(Sub(dateFormats) dateFormats.Weeks("dd/MM").Days("dd/MM")))).
Panes(Sub(panes) panes.Add().Clip(False)).
Pannable(True).
Zoomable(Sub(zoomable)
zoomable.Mousewheel(Sub(mousewheel) mousewheel.Lock(ChartAxisLock.Y)).
Selection(Sub(selection) selection.Lock(ChartAxisLock.Y))
End Sub))
Could you please fix this issue in a future version ?
Thanks and regards.
