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

Reproduction

1. Run this REPL
2. Set the height of the Chart to 90px
3. The chart is rendered upside down

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,

So the one thing that is missing for me from the zoom functionality is an event that tells me the selected values

i.e here I would like it to return: 2023/06/11 & 2023/06/18 

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

A possible option for the time being is to add each item in a dedicated series where you can specify its color.

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.

A possible workaround for the time being is forcing the Chart to re-render. To do so, you may wrap the Chart in a custom component and call StateHasChanged() in this component when the data is updated.

Here is a runnable sample: https://blazorrepl.telerik.com/wxEzwxbJ24WDjnMp11.

Support for ObservableCollection - allow the Chart component to use ObservableCollection data.

I would like to get an event that fires when the user click in the plot area of the Chart. 

Please see the links below to see examples of the scale break feature I'm looking for: Scale Breaks - ChartView - Telerik UI for WinForms.

https://docs.telerik.com/devtools/aspnet-ajax/controls/chart/features/scale-breaks

I know about Logarithmic Axis as well, but it's not exactly what I'm looking for.

I want to be able to specify and configure ErrorBars for the series like in Kendo UI for jQuery.

I would like to get an event that fires when the chart renders. 

I would like to be able to set default global options per series type with the SeriesDefault configuration. 

I want to be able to set a border-radius to the plot area to round the edges. 

I would like to customize the appearance of the Chart Legend

This is a feature request....please add box and whisker plot & sankey charts to your blazor and/or asp.net core chart controls.

Please add Funnel chart type such as the one available in Kendo.

Screen recording attached below, code to reproduce  it too.

Is it possible to change plot area background color on charts so that every second line is a different color.

I have attached a image with the background color look.

ADMIN EDIT

The current request targets the ability to color the whole plot area in alternating way. If you need to only color a certain range of the plot area, you may take a look at the Plot bands feature request.

While the most common use case is to alter the background color based on the major plot area units, we'd like to gather your feedback on how you'd expect the feature to behave - allow color altering on major units, minor units or custom steps.

I would like to control the font of the value axis labels.

The current version of the tooltip template context contains the information for the series color, but a particular data point might have a different color. Exposing such an option will allow better customization of the tooltip.
