    Tableau incorrectly reads values as nulls

    David Hou

      I have a very simple text file (attached).  All the columns are correctly read into Tableau with the exception of the RF_Frequency column.  Looking at the raw data, you can see that a few of the rows have a nonzero value.  However, Tableau treats all these values as nulls for some reason (it correctly reads everything else as zero).  The file opens correctly in Excel where I can plot against the time column, but I can't seem to do this Tableau.  Can someone help?
