I know that rqt_bag can help us see the content of bag files, however, I found that it can only show one frame(record) in one page. I want to see as many frames(records) as possible. Is there a way to list the content of a bag file? Thank you!

I found that there is a good way to see the big picture of the content of a bag file.

First, run the bag file use rosbag. And then, use rqt_plot to plot the curve of the data changing over time. This could help a little.

Your question title is not clear that you're looking for plotting, but from rqt_bag, you should be able to right-click on a topic and choose "plot" to plot it from within rqt_bag.
