When OnAxisLabelClick is set, the ChartCategoryAxisLabels do not get 'cursor: pointer' which is confusing for users because it makes it appear as if the axis labels are not clickable when they actually are.

===ADMIN EDIT===

In the meantime add the cursor: pointer CSS style to the labels. Here is a REPL example:

https://blazorrepl.telerik.com/cyvEYNbP27vsCSLG28

For real-time data purposes, I need to update the data and add new items. If I drill down and then add a new item, the Chart refreshes and goes to the top page (resets the drill down level to 0).

Reproduction: https://blazorrepl.telerik.com/QeOtQaOD46j4I3Ih46.

I want to be able to dynamically enable/disable the Pan and Zoom functionalities at runtime. Currently, the Chart does not react to such changes.

A possible option for the time being is to dispose the component and re-initialize it after changing the Pan/Zoom properties: https://blazorrepl.telerik.com/mSuNQkEj10nSug2k22.

I would like to synchronize several Charts, so when I move the mouse through one of them, the other two Charts show crosshairs at the same position as the first hovered Chart.

Prerequisite: Chart Crosshair

This functionality would be very useful for data analysis.

Moving the cursors within the chart itself, allows to define a range within the series, being able to offer useful data.

Examples:

Hello,

I want to connector to be directly connected with the chart. 

See https://dojo.telerik.com/AkEHuSiq/3 for reference.

Thank you.

Enhance the Chart date axis label format, so that it's culture-aware in globalization scenarios, and there is no need to set ChartCategoryAxisLabels Format explicitly.

In the meantime, here are a few workarounds for the case when the ChartCategoryAxis BaseUnit is Days and the Chart shows MM/dd labels even to non-US users.

• The easier option is to use a standard format string:

<ChartCategoryAxis BaseUnit="ChartCategoryAxisBaseUnit.Days"
                    Type="ChartCategoryAxisType.Date">
    <ChartCategoryAxisLabels Format="d" />
</ChartCategoryAxis>

• The above contains the year, so another option is MonthDayPattern:

<ChartCategoryAxis BaseUnit="ChartCategoryAxisBaseUnit.Days"
                    Type="ChartCategoryAxisType.Date">
    <ChartCategoryAxisLabels Format="@( CultureInfo.CurrentUICulture.DateTimeFormat.MonthDayPattern )" />
</ChartCategoryAxis>

• To display a shorter numeric month, use the MonthDayPattern to detect the day-month order and then set  a custom format string.

Razor

<ChartCategoryAxis BaseUnit="ChartCategoryAxisBaseUnit.Days"
                    Type="ChartCategoryAxisType.Date">
    <ChartCategoryAxisLabels Format="@( GetShortDayMonthPattern() )" />
</ChartCategoryAxis>

C#

    private string GetShortDayMonthPattern()
    {
        var mdp = CultureInfo.CurrentUICulture.DateTimeFormat.MonthDayPattern;
        var separator = CultureInfo.CurrentUICulture.DateTimeFormat.DateSeparator;
        string pattern = mdp.IndexOf("M") < mdp.IndexOf("d") ? $"MM{separator}dd" : $"dd{separator}MM";

        return pattern;
    }

In Kendo-React chart i can set the property "maxDivision" like this:

 <ChartCategoryAxis>
     <ChartCategoryAxisItem      
         maxDivisions={30}
         name="categoryAxisName"
         categories={categories}
...

and the chart will show only 30 dates in the displayed range, even if zoom in. 

Is there a way for doing the same thing in Blazor Chart? 

I tryed Type"fit" and MaxDateGroup but i need to show always all the points and this isnot a good solution.
I tryed ChartCategoryAxisLabels Step="number_of_labels_to_render" but when i zoom in the chart
will not show other dates.

Davide

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.

Reproduction: https://blazorrepl.telerik.com/cREDloaV42j7Z19G13.

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

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,

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.
