Hi!

I'm more than a little impressed with your Blazor efforts to-date, but there's one component lacking: a CandleStick chart.

<TelerikChart>
    <ChartSeriesItems>
        <ChartSeries Type="ChartSeriesType.Line" Name="Product 1" Data="@series1Data">
            <ChartSeriesMarkers Size="10"></ChartSeriesMarkers>

The Chart Tooltip does not render correct values for the data points when the chart is bound to a model, has multiple series and Template is used. The DataItem does not seem to work as expected.

ADMIN EDIT:

If the Chart is bound with Independent Series Binding the FormattedValue will get the correct values.

If the Chart has no Template the correct values for the data points will be displayed

At the moment it is always white. I often want it transparent so it can blend better with the rest of the content (e.g., it should be able to the color of the grid row it is embedded in).

I'm using version 1.1 of the UI for Blazor and have leveraged several different types of charts.  I now need to add click events on different parts of the chart so I can navigate to a drilldown page.  How can I accomplish this?

The idea is to ensure labels don't render on top of each other. If series values are close to each other, labels start overlapping. Having tooltips will let me remove the labels.

Example:

Hi, I can't figure how to use the Min/Max properties of the ChartCategoryAxis because if I set these properties, the chart disappears.

Please help me.

 

@page "/"

<TelerikChart>

    <ChartSeriesItems>
        <ChartSeries Type="ChartSeriesType.Line" Name="Test" Data="@mesures"
                     Field="@nameof(Mesure.Value)" CategoryField="@nameof(Mesure.Date)" Aggregate="ChartSeriesAggregate.Sum">
        </ChartSeries>
    </ChartSeriesItems>

    <ChartCategoryAxes>
        <!-- This is OK -->
        @*<ChartCategoryAxis BaseUnit="ChartCategoryAxisBaseUnit.Hours" Type="ChartCategoryAxisType.Date" BaseUnitStep="1"></ChartCategoryAxis>*@

        <!-- This isn't : nothing is displayed -->
        <ChartCategoryAxis Min="@MinDate" Max="@MaxDate" BaseUnit="ChartCategoryAxisBaseUnit.Hours" Type="ChartCategoryAxisType.Date" BaseUnitStep="1"></ChartCategoryAxis>
    </ChartCategoryAxes>

</TelerikChart>

@code {

    private DateTime MinDate { get; set; } = new DateTime(2019, 01, 01, 13, 0, 0);
    private DateTime MaxDate { get; set; }   = new DateTime(2019, 01, 01, 17, 0, 0);

    public class Mesure
    {
        public DateTime Date { get; set; }

Hi!

I'm building a Blazor Component using your TelerikChart.  To build my chart, I'm dynamically inserting the series name and the series data, which is pulled from a list.  I also have a button on the page that changes the dataset (last month, this month, next month, etc).  The button will rebuild the list of names and data, and Blazor will build the chart with a 'foreach' entry in the ChartSeriesItems section of the Chart Component.

The problem is that the Items are not cleared each time.  When I click the button, I'm getting previous values. In the example below, I have 3 data sets.  The first has 4 items, the second has 8 and the third has 6.  If the user clicks the second, showing all 8, then clicks the first, the chart will show the new 4, and the previous 5-8 from the second set.  

 My chart description in HTML is:

... 

<ChartSeriesItems> @foreach(Tuple<string, object[]> t in myData) { <ChartSeries Type="ChartSeriesType.Column" Name=@t.Item1 Data=@t.Item2 /> } </ChartSeriesItems>

... 

I have checked my data through debugging to ensure that the myData variable is correct (i.e. when I click the first data, it only has 4 items).  However, when the chart displays, it shows 8 items. 

Is there a CLEARDATA method or something I can call on the Chart to ensure that the data is reset each time?  I see that there is a Clear() in JavaScript, but I'm writing in only Blazor and C#, with no JavaScript.

I've attached the .razor page for your reference.  (As this is my test code, I'm using random number generation to get the data.)

 

Thank you so much for your help!!

-Cheryl Simpson

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.

I would like to visually distinguish a certain element in a series from the others if its value matches a given criteria (for example, value exceeds a threshold). Ideally, I'd want to add a hash to my bars, because I want to keep all items with the same color (I don't want to use the ColorField).

Something similar is available in Kendo: https://demos.telerik.com/kendo-ui/bar-charts/visuals.

Trying to upgrade an Angular app that uses WijMo charts. It graphs server and web performance data. I can easily make a line or scatter chart but your Blazor component is not very flexible using DateTime on the x axis. I got it to work on a Line but not a ScatterLine. Also, when using the Line with AxisType = Date, I can't get the  BaseUnitStep working. Is there an enumerator for that? It tries to write the x label for every hour over 10 days.

Hi there, it would be really nice if there were styling options available for the charts. I know that they styling gets inherited from the Telerik theme, but on the theme builder we can't get what we need without disrupting other UI styles. 

What we are looking for is really just a means to change the legend text color, and other text colors, as well as being able to set a background. 

For instance: 



Through the Telerik theme we would not be able to do this, maybe on one chart, but not different styles for each of the 3 charts. 

Possibly also having the chart to resize as the browser resizes, with an included Delay of 20ms. Just a thought.
