Position and arrow of a callout

Since callouts are placed on the results area of a chart, it is important that they are placed neatly in order to avoid obscuring the data that exists For this purpose we are offered three different settings.

Position - Angle: Specifies where the callout is placed compared to the data point that it relates to. An angle of 0 indicates that it is placed straight "east" of the data point.

Position - Distance: Specifies the distance between the data point and the middle of the text bubble. If the distance is set to 0 the text bubble is placed directly on top of the data point (which is thus hidden while there is no "Arrow").

Arrow - Base size: Specifies the width of the arrow from the data point to the text bubble.
