Legend
The Legend panel is located in the Customize->Basic accordion menu in the chart editor. The options presented let you set the visibility, layout and text style of the chart’s legend.
Legend
Visibility: On and checked means that the legend is active and visible to the user. Off and unchecked means that the legend is inactive and is not visible to the user.
Layout: Click the drop-down list to choose the way in which the legend items are flowed: vertically or horizontally.
Placement: Select a directional arrow to place the legend in that position. This option set lets you choose a color for the caption, set its font size, enable bold and/or italic text and set the caption’s alignment.
Float on top of plot area: On and checked means that the legend is detached from the plot area and the other elements will resize to fill the space left. The legend may then appear above and obscure other chart elements. Off and unchecked means that the legend is an integral part of the plot area and that other elements will be resized should the position of the legend change.

Click the B, U and I buttons to toggle bold, underlined and italic text styles, respectively. Click the drop-down list to select a font size for the legend’s text.
