How to change the size of scatter series in WPF Chart (SfChart)?

Description:

Scatter series plots an ellipse for each data point with definite size and fill. You may have to entail the variance in its size and color, especially when you have more than one series. This article describes how to change the size and color of scatter series.

Solution:

You can change the height and width of scatter series by using ScatterHeight and ScatterWidth properties in WPF Chart (SfChart). These values are pixel values and the default value for both properties is 20d. Also the Interior property is used to fill the ellipse as like other series.

These properties are also open for FastScatterBitmapSeries that you can use for high performance requirement.

XAML

<chart:ScatterSeries ScatterWidth="25" ScatterHeight="25" Label="Normal" Interior="DarkRed" XBindingPath="Year"                             YBindingPath="StandardRoom" ItemsSource="{Binding}"/>     
<chart:ScatterSeries ScatterWidth="60" ScatterHeight="60" Label="Double" Interior="Red" XBindingPath="Year" YBindingPath="DoubleRoom" ItemsSource="{Binding}"/>        
<chart:ScatterSeries ScatterWidth="40" ScatterHeight="40" Label="Luxury"  Interior="Blue" XBindingPath="Year" YBindingPath="ExecutiveRoom" ItemsSource="{Binding}"/>

C#

(this.scatterChart.Series[0] as ScatterSeries).ScatterWidth = 25;
(this.scatterChart.Series[0] as ScatterSeries).ScatterHeight = 25;
(this.scatterChart.Series[1] as ScatterSeries).ScatterWidth = 60;
(this.scatterChart.Series[1] as ScatterSeries).ScatterHeight = 60;
(this.scatterChart.Series[2] as ScatterSeries).ScatterWidth = 40;
(this.scatterChart.Series[2] as ScatterSeries).ScatterHeight = 40;
