Taking log of an array

I wish to take the natural log of my cloud mixing ratio array.
The results will have -inf if the input is 0.

How can i have this value assign to FillValue so that i can plot the non
infinity values.
Or how could i assign the 0 values in the cloud array to FillValues so
that log function will ignore.

I tried to set _FillValue=0 but when plotting i had the following warning
warning:ContourPlotInitialize: 0.0 not currently supported as a missing
value; expect inaccurate plot
