The 'placetitle' property

Character Vector

Valid for: Chart

The placetitle property determines where the Chart's title (or caption) and subtitle (if any) are drawn. It is a text string, and can be one of the values 'top', 'topleft', 'topright', 'bottom', 'bottomleft', 'bottomright'.

The default is 'top', meaning the title is centered above the chart.
