Mainscreen graph not scrolling using WD Linux

After two days of trail and error and a little frustration, I finally got WD working on a pc running Ubuntu 16.04 LTS 32-bit. The only problem I appear to be having is that the graph on the main screen is not scrolling. Data is being downloaded to the logfiles folder. On the ‘Advance/Misc Settings/Main Window Customise’ setting I have ‘Update main window graphs’ checked. If I go to ‘Graph Setup’ and change the ‘Graph Interval’ setting the graph will update with the latest data and that’s where it will stay until I change the ‘Graph Interval’ again. I am running Weather Display Ver 10.37L build 52. Any help or assistance would be greatly appreciated, thank you.

any errors under view, program event log?
is the data quality light on?
data received going up?
what weather station type?

The only error that is showing in the Program error log is “Invalid floating point operation” and it fills the whole screen and keeps going. Data quality light is solid green and Data received flashing red and green. The data counter keeps going up. I have a Davis Vantage Pro 2 Plus with a Weather Envoy USB data logger. Data is being recorded in the logfiles.

ok, that error is the problem
its a math error
(usually a divide by zero error)
a start over of the settings and data files (logfiles are OK…i.e you can convert the logfile to data file/last 31 days data file after)
might be in order to resolve

Well not sure what I did now but I’ve lost communication between my data logger and WD and can’t get it back. I’ve checked that the data logger is attached and the com ports are open. I am brand new to Linux so this is all a learning process for me.
