Can not create graph map

Which graph are you trying to create on a custom map? Is it for a single device?

Can you try logging into the shop and downloading and installing the newest version of the software to see if that solves the issue?

I'm trying to create a graph showing the bandwidth usage on the switch port

In the map designer tab for a map, you should be able to select the port that you want the graph for then look on the right side under graphs and there you will find a variety of graphs that you can put into the map to show the live, 30 day or 365 day graphs for that sensor.

You can also select the data tables to get the channels of the sensor as well if you want the direct values of the channels.

I made these graphs many times before, but now after upgrading PRTG it does not work anymore. Now I choose the graph eg "live" nothing happens ....

Could you try updating to the newest version to see if that resolves the issue?

If the newest version (13.3.5.2684) isn't available for the auto-update you can download the software from the shop.

In order to access the download link to the newest version you have to log into your online account and download it there.

Please use the email address the license is registered to and your password to log in here: https://service.paessler.com/en/login/

Once you have downloaded the newest version there, you can install it directly over the version currently running. The configuration and database will not be affected by installing the newer version over the old and the configuration is automatically backed up before this process.
