Populating Tooltip Text from something like a VLOOKUP

Hi stuhasic,

Firstly, the table visual in Power BI Desktop doesn’t  provide Tooltips feature like other charts(for example, stacked column chart). You are not able to show text field as you describe when you hover over any of the addresses in table visual.

Secondly, as a workaround for this issue, you can create extra column to present what you want to show, add the extra column in the table visual and adjust the column width so it just shows “…”(the Auto-size column width and Word wrap should be turned off for the table visual). This way, when you hover over the “…”, text us displayed.

Thirdly, to create the extra column, you would need to create a new table using the following DAX. Then create relationship using Device IP field in the new table and Telstra WAN field in IPoutages table.

NewTable = SUMMARIZE(Failures,Failures[Device IP],"failure time", MIN(Failures[Failed Since]))

After that, create the extra column in IPoutages table using DAX below, then add the column to your table visual.

Column = RELATED('NewTable'[failure time])

Thanks,
