Log or Log10 and Visuals

[Evogelpohl]

I have data that needs to be re-calculated to the LOG or LOG10(value) so that I can reduce the extreme highs and lows when graphing activity by day (date as x-axis)

I created the =Log10(of a measure) in Excel PowerPivot, using DAX.  It calculates ok.

Import the data from my OneDrive for Biz into PowerBI.  When I try to visualize in PowerBI, I get an error. 

Unrecognized fields in this visual
We are not able to identify the following fields: LL_Audit_Logins[(Log) Login Events]. Please update the visual with fields that exist in the dataset.

Anyone else getting this error?

Does your field name really include parens? [(Log) Login Events]. First thing I would do is get rid of those and go with something like [LOG Login Events].

Thanks.  I removed the ().  I get a new error when i put both this measure and the Date(Date) dimension on the x-axis.  The error is 'Chart data contains infinity values'.

I can visualize in Excel however.

I think i may have confused Excel's feature of scaling the y-axis logarithmically to flatten and re-scale extreme values using Log(x) of the value with literally creating the Log(of the value).

It appears that PowerBI doesn't have this feature.  I'll see if i can find it on UserVoice.
