By default, the borderline of Chart.ChartArea for new charts are visible. All other border lines for all other components of a chart are not visible by default.

If a default borderline is visible, which is the case for Chart area borderline, the default configuration for the line is:

• Color: Color.SystemColor.AutomaticLine
• Style: ChartLine.LineStyle.Solid
• Weight: ChartLine.LineWeight.Narrow

If a default borderline is invisible, as is the case with legends, data labels, titles, and axes, the defaults are as follows:

• Color: Color.SystemColor.Black
• Style: ChartLine.LineStyle.None
• Weight: ChartLine.LineWeight.Narrow
