Customize grid lines by modifying the Type Properties for the grid type. 
 You can customize grid types in the following ways: 
- Change the line color, weight, and pattern of the entire grid line. (Modify the Bubble grid type, or create your own.) 
 
- Hide the center segment of the grid lines to create a gap, displaying only the end segments in views. (Modify the Bubble Gap grid type, or create your own.) 
 
- Display the center segment of the grid line using a different line color, weight, and pattern than the end segments. (Modify the Bubble Custom Gap grid type, or create your own.) 
 
To make these customizations, you modify a grid type. In views, all grid lines of that type reflect the changes.
