 If logged data on storage (either SD card or internal flash) is available, the **Display log file** becomes clickable. By default, it will display the logged data in the browser.  
 To access the logged data itself (in the file `datalog.txt`), use the `/D` URL command mentioned above.  
-By default, "Display log file" displays the log data of the most recent `n` calendar days (`n=DEFAULT_DAYS_TO_PLOT`, configurable in `BSB_LAN_config.h`). Subsequently, controls on the web page can be used to select a different range, depending on the data contained in the log file

 - Users can interactively highlight plot lines for improved overview (mouseover on legend entries)
 - Users can interactively disable plot lines for improved overview and vertical scaling (click on legend entries)

+For further processing, you can use this [Python script](https://github.com/DE-cr/BSB-LAN/tree/BSB-LAN_evaluate_datalogs/BSB_LAN/scripts/BSB-LAN_evaluate_datalogs) that takes BSB-LAN's log output to create pivoted CSV files that can be used for more insightful diagrams.
