 ## Help Text
 
     Usage:
-      -h | --help                                       Prints help
-      --netdev=<device_name>                            Check network traffic on specified device
-      --netdev_width=<width>                            Sets the min-width of the netdev output (default 10)
-      --netgraph_max_bytes=<bytes>                      Enable "graph" output when polling network traffic
-      --interval-sec=<seconds>                          Output at intervals of <seconds> (default 5)
-      --acpi-builtin                                    Use "acpi -b" built-in fetching (battery info, with color)
-      --regex-cmd=<cmd>[SPLIT]<args...>[SPLIT]<regex>   Use an output of a command as a metric
-      --time-format=<date format string>                Set the format string for the date

 a history graph of network traffic. A sane value for `<bytes>` can be 1048576,
 which is 1 MiB.
 
+Specify "dynamic" instead of a bytecount (such as
+`--netgraph_max_bytes=dynamic`) to have the graph dynamically resize based on
+the maximum amount of bytes transferred in an interval.
