Last 24 Hour Graph Gone

I had problems today with power going on and off which shut down my computer. The last time I logged in and started WD, the graphs were done and everything in the graph area was wrong. How might I restore the graphs? See attached:


Action Convert logs should do it…

go
action
convert WD logfiles to data files
click on convert
then click on recreate last 31 days data file

Thanks!!! That did it.
