Please see RViz documentation, its Built-In Display Types and particularly LaserScan display type.

How is this the accepted answer? If you arn't going to answer the question properly, THEN DON'T ANSWER IT!!!!! People like you are why the learning curve for ros is a cliff. The documentation sucks, and telling people to go and read it instead of answering a simple question is why it's so steep.

@Ben12345 If you read the suggested pages and still have questions, then ask them. (There is a button on the top right "Ask your question"). Also, I highly recommend to go through the ROS Tutorials and RViz User Guide.

After launching Rviz, I set /scan as topic in LaserScan and set /laser as Fixed Frame in Global Options. Of course, I added LaserScan to Displays from default. I could see the laser data.

For new people to ROS, this answer works fine. Make sure to change the Global Options. Nevertheless, reading the documentation will help you further away.

@Ken_in_JAPAN Does /laser refers to the laser link in urdf?

stefanvan ( 2018-04-06 04:28:39 -0500 )edit

without laser link on actual URDF, still you can visualise /scan data by just mentioning laser at global option.

Since I've wasted way too much time for this simple task, here an additional hint: If there is an error message like For frame [base_scan]: Frame [base_scan] does not exist, set the fixed frame in global options to exactly this name base_scan. Also see my answer here: https://answers.ros.org/question/5988...
