{remarks}
This is an instance of [{{ChartFillPattern}}|ChartFillPattern].

For chart regions that normally have a filled background (such as {{Chart.ChartArea}}), this will be {{Solid}} by default.  For chart regions that normally have no background (such as [{{ChartText}}|ChartText] instances like {{Chart.ChartTitle}}) this will be {{None}} by default.

Setting {{Pattern}} to {{null}} will throw an {{ArgumentException}}.
