All individuals that have a valid date for either a birth or marriage can have that date rounded to the nearest decade after the entered. (This feature will change in the future to round to just the year per Gramps make vague function.) Additionally, middle names can be changed to just show initials. (This feature will change in the future to just remove middle names altogether.) Finally, private records for individuals can be included or not. If not, the individual node will contain the words "Private Record" for all those individuals marked private in Gramps.

[[File:Network_chart_menu_Trim_1.png|thumb|300px250px|left|Trim Menu Example 1]] [[File:Shakespeare_network_trim_1.svg|thumb|200px|right|Trim Example 1]] The Trim menu allows "trimming" of the database to display less individuals in the Network Chart. The Trim Descendants option trims all descendants "below" the selected individuals. The Trim Ancestors option attempts to trim all ancestors "above" the selected individuals. Individuals by marriage will also be removed depending on their location in the network relative to the person trimmed. Both options allow entry of multiple people. The Trim Menu image shows the selection of individual I0118 to trim descendants and I0111 to trim ancestors. The result is shown on the right in the Trim Example 1. Note the nodes of the individuals selected on the trim tab are bordered with a red dashed trim.

[[File:Network_chart_menu_Trim_2.png|thumb|300px250px|left|Trim Menu Example 2]] [[File:Shakespeare_network_trim_2.svg|thumb|200px|right|Trim Example 2]] Trim Menu Example 2 shows the selection of additional individuals to trim. However, this example will generate "orphans" or individuals with no connections as a result of the trimming operation. This is shown in Trim Example 2, note the individuals in the top right corner.

  Trim Menu Example 2 shows the selection of additional individuals to trim. However, this example will generate "orphans" or individuals with no connections as a result of the trimming operation. This is shown in Trim Example 2. Note the three isolated individuals in the top right corner including one of the individuals selected in the trim menu.  [[File:Network_chart_menu_Trim_3.png|thumb|250px|left|Trim Menu Example 3]] [[File:Shakespeare_network_trim_3.svg|thumb|200px|right|Trim Example 3]]   The Trim Groups option will trim smaller groups/trees or individuals that are disconnected. You must enter the minimum number of individuals in a group/tree to display. For databases with more than 1500 individuals this option is required and the minimum number is set to 2. This will force all disconnected single individuals to be removed from the graph. Selecting a number greater than the largest group/tree will return only the largest tree or those trees that are equal in size. For this example the Trim Groups has been selected with a size of 2. The result removes the isolated individuals from the graph as shown in the Trim Example 3 chart.
