Formatting the legend, title, and size of a chart
When you modify a chart, you can add a legend title, choose to display or hide the legend on the chart, and determine the legend position. You can modify the font, size, color, and style of the legend and in some cases legend items. You can also choose to display or hide the chart title and modify the appearance of the title text in the usual ways, by changing its font properties. In addition, you can modify the chart’s size and the display dimension of a chart.
