Tableau Tooltips - Full beginners guide including Viz in Tooltips.

Forget the old tooltip hacks - here's everything tooltips can do today, right through to embedding a whole chart inside one.

  • Tooltips are generated automatically, but you can add any measure or dimension to one by dragging it onto the Tooltip card in the marks pane, including fields you don't want shown in the visualisation itself.
  • Always check the aggregation when adding fields to a tooltip - summing a discount, for example, is misleading, so aggregate at the right level rather than just accepting the default.
  • The little ruler at the top of the tooltip editor controls tabbed spacing, letting you align values neatly to the right by inserting tabs and dragging the slider.
  • The command buttons let you keep/exclude as filters, create visual groups and sets, run Explain Data for outlier diagnostics, and view the underlying row-level data.
  • Viz in Tooltips embeds a sheet inside a tooltip; changing the filter field from 'All fields' to a chosen dimension controls how the embedded chart responds to what you hover over.

This video covers everything tooltips can do in Tableau, from the free auto-generated tooltip through formatting and command buttons to embedding an entire chart inside one with Viz in Tooltips.

Built using the Sample Superstore workbook, starting from a simple scatter plot with no dimensions in the tooltip. The goal is to show what's possible today rather than the older tooltip hacks many tutorials still teach.

The Breakdown
  1. Build a scatter plot and see the default tooltip 2:18

    With only two measures on rows/columns, Tableau shows one aggregated point and a sparse tooltip; adding a dimension like segment to colour breaks the data into components the tooltip can describe.

  2. Add extra measures and dimensions to the tooltip 4:08

    Drag any field, even one you don't want visible in the chart itself, onto the Tooltip shelf in the marks pane to add context without affecting the visualisation.

  3. Watch the aggregation on added fields 7:36

    Fields default to sum, which is wrong for things like discount; check and change the aggregation (e.g. average) so the number shown is actually meaningful.

  4. Open the tooltip editor and learn the anatomy 8:50

    The tooltip pane is mostly a formatting toolbar (font, size, bold, colour, clear formatting) plus one non-formatting option covered later for inserting extra content.

  5. Choose on hover vs responsive display 10:36

    Responsive tooltips open a command bar on click with extra actions; on hover tooltips appear automatically after a short delay, with no command bar.

  6. Use the ruler to control tab spacing 11:46

    The ruler at the top of the editor controls where tabbed values align; inserting a tab before a field and dragging the slider lines values up neatly, especially useful with long dimension names.

  7. Format for hierarchy and trim tableau-speak 15:47

    Bold headers, group related fields together, remove verbose default text and reorder content so the tooltip reads with a clear hierarchy rather than dumping fields in insertion order.

  8. Command buttons: keep/exclude, groups, sets, Explain Data, view data 18:25

    Keep only/exclude apply the same filters as dragging to include/exclude; grouping and set creation from the command bar visually bundle marks into new dimensions; Explain Data flags anomalous data points with drill-down charts; view data exports the exact underlying rows for that mark.

  9. Insert a sheet with Viz in Tooltips 29:20

    Use Insert > Sheets in the editor to embed a whole chart (e.g. least profitable products per city) inside the tooltip, then change the filter setting from 'All fields' to a specific dimension like state/province so the embedded viz responds correctly to what's hovered, rather than showing only the exact record.

  10. Dashboard actions inside tooltips 37:41

    Briefly shown: an action set up between dashboard tabs surfaces as a clickable link inside a tooltip, applying a filter on the target tab when clicked — flagged as a topic for another video.

Worth Knowing
  • Sum is the default aggregation for any field dragged onto Tooltip, which can silently mislead (e.g. summing a discount) if you don't check it.
  • Viz in Tooltips defaults to 'All fields', meaning the embedded chart shows only that exact record; you usually need to change it to a broader dimension to get a genuinely useful mini-chart.
  • The embedded visualisation has a maximum width/height and can report the view is 'too large' if it doesn't fit.
  • Allow selection by category (the tooltip's clickable links) is powerful for cross-highlighting but can confuse users who don't expect it, so it can be switched off.
Use It When

Reach for this whenever a default Tableau tooltip is too sparse or too messy to actually inform a viewer, or when you want a single hover to reveal a fuller supporting chart instead of building a separate dashboard view.
