gps-waypoint plot and mapviz issues

[Masoumehrahimi]

hi

I want to plot gps-waypoints, but after running the related launch file, and saving a number of waypoints, i do not know how to plot it? how can i use these waypoints to plot?
I have also launched mapviz as well, the map is loaded but i do not know how to see the gps waypoints in the map

would you please guide me what to do?
thanks

Hello, is your mapviz map offline? How to load it？
