Dear,

Each line in my database is giving me information about a tunnel, one of the column is calling tunnel\_status and has values "up" and "down" another column has the name "tunnel number" with values "tunnel 1",... "tunnel 8". What I want to do now is to create a graph which gives me the latest value of each tunnel. Preferable is an histogram.

Kind regards,  
Amon

Hey @Amon, if you'd like to see the latest `tunnel_status` for each of the trains, we can't create a Histogram of this because `tunnel_status` is a string. We can however use the data table visualization to get you this information.

Using Dev Tools, we can create some sample data to play around with:

```auto
