+
+## Angular Chart Marker Size
+
+You can control the exact device-independent pixel dimensions of data point markers by setting the `MarkerSize` property on any series that supports markers. This gives you precise control over how large markers appear on screen, regardless of the marker template or style being used.
+
+By default, marker sizing is determined by the series marker template. When you set `MarkerSize` to a specific numeric value, all markers in that series render at that exact device-independent pixel width and height. Setting `MarkerSize` back to `NaN` restores the default template-driven sizing.
+
+The `MarkerSize` property is available on all series types that derive from `MarkerSeries`, including `LineSeries`, `SplineSeries`, `AreaSeries`, `ColumnSeries`, `ScatterSeries`, `ScatterLineSeries`, `ScatterSplineSeries`, and polar/radial series types.
+
+The following code examples show how to set `MarkerSize` to 30 device-independent pixels on a `ScatterLineSeries` in the `XamDataChart` control:
+
+
+
+
+
+
+
+To reset markers to their default template-driven size, set `MarkerSize` to `NaN` (or remove the attribute in markup):
+
+
+
+
+
+The following sample demonstrates `MarkerSize` on scatter series with an interactive editor:
+
+<Sample src="/charts/data-chart/scatter-marker-options" height={500} alt="Angular Chart Marker Size Example" />
+
+<DocsAside type="note">
+For `BubbleSeries`, the `MarkerSize` property does not override the bubble radius, which is controlled by the radius data column and the `RadiusScale`. Bubble sizes remain entirely driven by the data and scale configuration.

+<div class="divider--half"></div>
+
+## Angular Chart Checkmark Marker Type
+
+The Ignite UI for Angular charts include a `Checkmark` option in the `MarkerType` enum. This marker renders a V-shaped checkmark icon inside a circle on data points in your chart.
+
+You can apply the `Checkmark` marker type to an individual series by setting its `MarkerType` property to `MarkerType.Checkmark`. To use the checkmark shape for all series in the chart simultaneously, set the chart's `MarkerAutomaticBehavior` property to `MarkerAutomaticBehavior.Checkmark`.
+
+The `SeriesViewer.CheckmarkMarkerTemplate` property defines the marker template used for series with a checkmark marker type, and can be used to customize its appearance across the chart.
