For example, negative data points get highlighted in red color on setting <a href="C1.WPF.Sparkline.4~C1.WPF.Sparkline.C1Sparkline~ShowNegative.html">ShowNegative</a> property to true, while the last data point gets highlighted in green color when the <a href="C1.WPF.Sparkline.4~C1.WPF.Sparkline.C1Sparkline~ShowLast.html">ShowLast</a> property is set to true. However, you can modify this default behavior and highlight data points in a color of your choice, making Sparkline more customizable for users from appearance perspective.</p> <p>The <a href="C1.WPF.Sparkline.4~C1.WPF.Sparkline.C1Sparkline.html">C1Sparkline</a> class provides various properties to customize marker colors in code.
