Graph with the second marriage

Is it possible to generata graph with the secound marriage?
Something like this:

Gramps 5.1.4 Windows 10

Try the Graph View add-on view mode.

It has some prerequisites but it is worth troubleshooting. And since you’re using the Windows version, those should already be installed.

A graph can be generated using the relationship graph. This will include all the people that are included for the graph. One way to do this is to create a person filter (menu > edit > person filter editor) to select the people that you want to include, then when creating the graph, in the relationship graph dialog, report options tab, select the filter that you just created.
