Same as other ITONICS Tools, the Network Graph has a filter section to narrow down your search results. To open the filter menu click the Filter button next to the Network Graph Label. Note that the Network Graph can only display 200 Elements at once.
Find the filter you want to apply and click to open the filter options. Next, select one or multiple options to apply the filter to the Network Graph. You can also save the filter to easily access the filtered view next time you visit the Network Graph. To find out how you can save and edit filters, visit this Knowledge Base Article.
