top 5 VALUES by month

Hi,

Thank you for your message.

Please check if Items table has other columns that influence the measure [TotalUsage] in the visualization.

Once the columns are identified, please write the measure something like below.

Top 5 item usage by month: = 
CALCULATE (
    [Usage measure:],
    KEEPFILTERS (
        TOPN ( 5, 
ALL ( 'Item'[Item],'Item'[columnAinthevisualization],'Item'[columnBinthevisualization], and so forth  ),  [Usage measure:], DESC )
    )
)

Or, if it is OK with you, please share your sample pbix file's link and then I can try to look into it.

Thanks.
