I would like to be able to stack series on a range chart. Currently the best hack recommended by Telerik is to show two charts on top of one another, with no interactivity or legends, https://blazorrepl.telerik.com/wHPclTFm28WuoSOp57.

Thank you

It would be fantastic to be able to visualize boolean data on a time based chart. We have a lot of time series data, and a good bit of it is boolean. It would be very beneficial to be able to plot that data along side our numeric data to provide context to both. 

Example (blue/green bar at bottom of chart):

Hello support team,

from the donut chart example under https://demos.telerik.com/blazor-ui/chart/donut-chart:

Is there a specific reason why all charts have a Template sub-property for the ChartSeriesTooltip construct but the Template field with the template syntax for the ChartSeriesLabels construct? I would favour a unified syntax for both of the properties, if this is possible somehow...

Is this planned for the future to be unified? Especially formatting like shown under https://docs.telerik.com/blazor-ui/knowledge-base/chart-format-percent is not as simple as I would have expected as nobody wants to touch JavaScript code literally :D (Also, localizing data seems quite difficult with that technique).

The best option in my opinion would be to remove those templates completely and just let the user decide what to show there while using a field called e.g. TooltipMappingName and LabelMappingName or something like that. This gives the chart the maximum of configuration possible.

Example:

<TelerikChart>
    <ChartTitle Text="What is you favourite sport?"></ChartTitle>
    <ChartLegend Visible="true" Position="ChartLegendPosition.Top"></ChartLegend>

    <ChartSeriesItems>
        <ChartSeries Type="ChartSeriesType.Donut"
                     Data="@Data"
                     Field="@nameof(ModelData.Value)"
                     CategoryField="@nameof(ModelData.Category)">
            <ChartSeriesTooltip Visible="true" Context="item" TooltipMappingName="@nameof(ModelData.Tooltip)"/>
            <ChartSeriesLabels Position="ChartSeriesLabelsPosition.OutsideEnd"
                               Visible="true"
                               Background="transparent"
                               LabelMappingName="@nameof(ModelData.Label)">
            </ChartSeriesLabels>
        </ChartSeries>
    </ChartSeriesItems>

</TelerikChart>

@code {
    public class ModelData
    {
        public string Category { get; set; }
        public int Value { get; set; }
  public string Tooltip { get; set; }
        public string Label { get; set; }
    }

    public List<ModelData> Data = new List<ModelData>()
    {
        new ModelData()
        {
            Category = "Football",
            Value = 35,
   Tooltip = "35%",
   Label = "Football: 35%"
        },
        new ModelData()
        {
            Category = "Basketball",
            Value = 25,
   Tooltip = "25%",
   Label = "Basketball: 25%"
        },
        new ModelData()
        {
            Category = "Volleyball",
            Value = 20,
   Tooltip = "20%",
   Label = "Volleyball: 20%"
        },
        new ModelData()
        {
            Category = "Rugby",
            Value = 10,
   Tooltip = "10%",
   Label = "Rugby: 10%"
        },
        new ModelData()
        {
            Category = "Tennis",
            Value = 10,
   Tooltip = "10%",
   Label = "Tennis: 10%"
        }
    };
}

Best regards,

Currently, scatter line plots do not support the stepped line style. This is something that would be hugely beneficial to us in our heavy utilization of scatter line plots with time series data.

When a Chart Series has a click handler defined, I think the cursor should be set to 'pointer' when the user is hovering over the series so the user knows its clickable. Currently the Chart Series Labels change to a pointer cursor when you hover them, however they are not clickable. Not sure if this was the intended functionality, but it seems backwards to me.
