![]() Is a user-defined angle and can be used, for example, to show Rotation angle: 0 to 360 degrees rotates clockwise, 0 to -360 Use Calibration Angle to manually set the The true north calculation is based on the coordinate system using the center point of the data frame. True North-North arrow angle uses geodetic north, or the direction to the north pole.Data Frame Rotation-North arrow angle uses the rotation of the data frame.You can control the alignment of the north arrow by selecting one of the following options: The size of the north arrow is in points. North arrow properties include its style, size, color, and angle. When that data frame is rotated, the north arrow element will rotate with it. ![]() A north arrow element maintains a connection to a data frame. North arrows indicate the orientation of the map. If you click Properties while inside the initial configuration dialog box of a scale bar, for example, you won't see the Size and Position tab or the Frame tab. You can only change the size, position, and frame of an element after it has been placed on the map. Dragging a handle away from an element enlarges it, while dragging a handle toward an element reduces it. You can change the size of map elements by selecting them and dragging the selection handles. Map elements aren't always the size you want when they're added to a map. Therefore, updating the name inside the Data Frame Properties dialog box will also update its name in the table of contents. Map automation scripts use the names of elements to identify which elements are to be modified by the script.Ī data frame's name property is always the same as what's shown in the table of contents. The element name is also very important for map automation scripts using the arcpy.mapping module. By default, the name is based on the element type, such as Scale Line or North Arrow, but you can change it to a unique or more descriptive name on the Size and Position tab of the element's Properties dialog box. For example, when the layout is in draft mode, each element is drawn as a hollow frame containing the name of the element. Learn about other map elements such as titles graphic elements, pictures, and neatlines reports and graphs.Įach map element has a name used to identify the element. North arrows, scale bars, scale text, and legends are examples of such elements. Some map elements are related to the data in data frames.
