+## Description
+
+I need to configure a ScatterLine Chart so I can control the marker used for each data point independently. I want to mark some points as "special".
+
+This KB article answers the following questions:
+- How to mark specific data points in a ScatterLine Chart as special?
+- How to customize separate markers in a Blazor ScatterLine Chart?
+- How to use different markers for special data points in a ScatterLine Chart?
+
+## Solution
+
+The marker type is defined per series level, so it is not possible to set different markers for the different data points out of the box.
+
+To mark specific data points as "special", follow these steps:
+
+1. Use a Chart type with lines for the first series and provide it with all available data points (for example, [ScatterLine]({%slug components/chart/types/scatterline%})).
+
+2. Use a Chart type without lines for the second series, so the lines do not mix (for example, [Scatter]({%slug components/chart/types/scatter%})).
+
+3. In the second series data include only the points that you want to mark as special.
+
+4. Increase the [ZIndex](/blazor-ui/api/Telerik.Blazor.Components.ChartSeries#collapsible-Telerik_Blazor_Components_ChartSeries_ZIndex) of the second series to ensure its points are rendered on top of the first series.
+
+5. Choose a different marker type for the second series from the options available in the [`ChartSeriesMarkersType`](/blazor-ui/api/Telerik.Blazor.ChartSeriesMarkersType) enum. Once available, you may consider using the [visual template](https://feedback.telerik.com/blazor/1582456-custom-rendering-for-the-chart-series-markers-visual-template) to completely customize the markers.
+
+5. Optionally, set a different [color](/blazor-ui/api/Telerik.Blazor.Components.ChartSeries#collapsible-Telerik_Blazor_Components_ChartSeries_Color) for the second series to distinguish the "special" points further.
