I want horizontal and vertical lines in the chart to act as markers (limits, thresholds). It would be awesome if there was a way to simply draw a horizontal and vertical lines, bound to a collection of y and x data respectively.

Something like the below would be nice 

    <TelerikChart>
        <ChartSeriesItems>
            <ChartSeries Type="@ChartSeriesType.Line" Name="@P_Name1" Color="blue"
                         Data="@P_Data1"
                         Field="@P_Field1"
                         CategoryField="@P_CategoryField1">
                <ChartSeriesLabels Visible="true" Template="#=dataItem.P_Description#" />
                <ChartSeriesMarkers Size="4" />
            </ChartSeries>
            <ChartHorizontalLines Data="@YLinesData"/>
            <ChartVerticalLines Data="@XLinesData"/>
        </ChartSeriesItems>
</TelerikChart>

@code{

List<double> YLinesData, XLinesData;

}

You can find some more details and ideas for workarounds here to consider in the meantime.

To reproduce the problem, hover over the last value of the series. While the Tooltip enters, it causes horizontal and vertical scroll and flickers. Then, it is positioned correctly.

The issue is better observed if you increase the transition speed of the Tooltip wrapper.

A possible workaround for the time being is to alter or stop the Tooltip animation with CSS. Here is a runnable sample demonstrating the approach: https://blazorrepl.telerik.com/QnEjvIOC04hXA6W709

It would be nice to make the label container less than the width of the element so that it stands out more.

I know that it can be set to different colors and transparent but adjusting the width would be a nice addition as well.

Hello,

Please allow us to distinguish which mouse button triggered the SeriesClick event.

The Scatterline Chart is flipped upside down if the Height is under 100px.

Hi,

We are implementing chart control in our application and we noticed spikes in the chart when we are using time series that contains UTC timestamps with milliseconds that are divisible by 100. The issue is reproduceable on Telerik REPL as well and I am attaching the REPL link as well

Telerik REPL - Chart

I was wondering if you guys can provide some insight from your end as to whether that is indeed a bug and some work arounds and timeline on when we can resolution from your end.

Cheers,

Hi,

I would like to be able to show / hide a serie by clicking to a legend.

Is there a way to do it actually ?

How do I stop a column chart generating over the hover-over effect?

The property exists in the Kendo Chart.

It would be helpful to me if this chart type was supported.

https://demos.telerik.com/kendo-ui/range-bar-charts/index

In need a chart that has a shaded area between a max and min set of curves, indicating the allowable area

Like this one: https://demos.telerik.com/kendo-ui/range-area-charts/index

I want to be able to set different colors for the separate series items.

Currently, the Chart does not plot anything when zero values are included in the dataset on a logarithmic axis.

Reproduction: https://blazorrepl.telerik.com/cdYgkWFH23W9PVon54

At least the "Success" data should be plotted.

I am trying to programmatically update the Chart data during runtime to display live data. The Chart does not seem to refresh and show this change in the viewport.

I've tried:

• using an Observable Collection;
• creating a new collection instance and reassigning the Data parameter;
• calling the Refresh method;

The result is the same - the Chart does not react to the data change. This applies to other component parameters as well.

Hi,

Just a bug I have found. I have found something similar before with the DateTime format of a category axis.

Please note the single lowercase 't' in the below appears to be being interpreted by the compiler as 'time' identifier (AM or PM). In this case, it is printing on the chart label as 'a'.

<ChartValueAxes>
     <ChartValueAxis AxisCrossingValue="@AxisCrossingValue">
          <ChartValueAxisLabels Format="@("{0}" + " a b c d e f g h i j k l m n o p q r s t u v w x y z")"></ChartValueAxisLabels> 
    </ChartValueAxis>
</ChartValueAxes>
