Interactivity & cross-filtering

The Bump Chart is a first-class Power BI citizen: clicking a line filters the rest of the page, the legend filters by series, right-click opens Power BI's own menu, and everything is reachable from the keyboard.

Selecting series and points

Action	Result
Click a line	Selects that series across every period and cross-filters the report.
Click a marker	Selects that series at that period — a single data point.
Click a legend item	Selects the series, the same as clicking its line.
Ctrl+click (⌘+click on Mac), or Shift+click	Adds to or removes from the selection.
Click empty space	Clears the selection.

What you see when something is selected:

• The selected lines and markers stay at full strength.
• Everything else dims to 30% — lines, markers and rank numbers together.
• Unselected legend items fade too, so the legend tracks the chart.

Line or marker?

Both cross-filter, but they filter different things: a line filters the report to that series for the whole timeline, a marker filters it to that series in that one period. Use marker selection to answer "what else happened in Q3 for this product?".

Selections also combine across visuals: ctrl+click a line here and a bar in another visual, and the report is filtered by both.

Filtering from the legend

Clicking a legend item selects its series exactly as clicking the line does — filtering the whole report by every row belonging to that series, not only the periods on screen.

• Ctrl+click to build a multi-series selection.
• Click empty chart space to clear it.

Right-click menu

Right-clicking a line or a marker opens Power BI's own context menu for that data point — Include, Exclude, Drill through, Show as a table, Copy, and any drill-through pages you've defined.

Right-clicking empty plot area opens the visual-level menu instead.

Tooltips

Format → Tooltips — on by default.

Setting	Options	Default
Show	On · Off	On
Display units	Auto · None · Thousands · Millions · Billions	Auto
Decimal places	0 – 15, or blank	(blank)

Hovering a marker shows, in order:

1. Series — labelled with your Series column's name.
2. Period — labelled with your Time column's name.
3. Value — labelled with your measure's name, formatted as described below.
4. Rank — the position in that period.
5. Your Tooltips fields, in the order you dropped them.

note

Tooltips are attached to the markers, not to the lines. With Format → Data Points → Show turned off there is nothing to hover, and no tooltip appears.

Value formatting in tooltips

The Value row starts from the measure's own model format string — currency symbols, percentages, thousands separators — and the two settings on this card then adjust it:

Setting	Effect
Display units	Abbreviates large numbers: 1.2M, 847K. Auto picks the unit per value, so a small number beside a large one still reads as 847 rather than 0M.
Decimal places	Forces a fixed number of decimals. Leave it blank to let the format string decide — usually the right answer.

Both settings apply only to the Value row. Fields you add to Tooltips keep their own model formatting, which is the reason to add them as separate fields.

Report page tooltips

The Bump Chart supports report-page tooltips — a whole mini-report shown on hover, instead of the standard list.

1. Build a tooltip page: Format page → Page information → Allow use as tooltip.
2. Select the Bump Chart and leave Format → Tooltips → Show on.
3. In Format → General → Tooltips (Power BI's own card), set the type to Report page and pick your page.

The hovered marker's identity — that series, in that period — is passed to the page, so measures on it are filtered to that point.

note

If Show is off, no tooltip of either kind appears: the visual never asks Power BI to show one. It's the most common reason a report-page tooltip seems not to work.

Being filtered by other visuals

Slicers, filter-pane filters and cross-filters from other visuals all reach the Bump Chart normally. How they reach it changes what you see, and for a ranking chart the difference matters:

Interaction	What the Bump Chart does	Ranks
Highlight (Power BI's default)	Dims the series that aren't part of the selection, keeping the whole field on screen	Unchanged — still calculated over all the data
Filter	Redraws with only the rows that survive the filter	Recalculated on the filtered subset

Both are legitimate; pick the one that matches the question:

• Keep highlight to answer "where does this segment's champion sit in the overall table?"
• Switch to filter to answer "who leads within this segment?" — for example, ranking products within the region chosen in a slicer.

Change it with Format ribbon → Edit interactions, then choose the filter icon over the Bump Chart for each source visual. Slicers filter by default, so slicer-driven re-ranking works out of the box.

Sanity check

If ranks look wrong after a cross-filter, this is almost always why: the numbers you see were computed before the highlight was applied. Switch that interaction to filter.

Bookmarks

Selections are captured by bookmarks and restored when the bookmark is applied, including selections made from the legend. All Format-pane settings — Top N, reverse rank, colours — are report state and are stored in bookmarks like any other visual's formatting.

Dashboard tiles and read-only contexts

When the visual is pinned to a dashboard tile, Power BI disables interactions: lines and markers can't be selected and clicks don't filter. Tooltips still work, and the chart renders exactly as it does in the report.

Keyboard and accessibility

Key	What it does
Tab / Shift+Tab	Moves through the series lines and then the markers.
Enter / Space	Selects the focused line or marker, cross-filtering the report.
Ctrl / ⌘ / Shift + Enter	Adds the focused item to the current selection.
Esc	Returns focus to the visual container, following Power BI's own convention.

• The focused line or marker is drawn with a halo that follows its shape, using the system highlight colour, rather than a rectangular outline — so a focused line is unmistakable even in a crowded chart.
• Every line is announced with its series name; every marker with its series, period and rank.
• High contrast mode is fully supported: all colours come from the Windows system palette. Because every series is then drawn in the same foreground colour, keep Data Labels or the legend on so series remain identifiable — see High contrast.
• Selection is never signalled by colour alone: unselected series are dimmed, and the rank numbers stay legible throughout.

Focus mode and export

The Bump Chart renders normally in focus mode and in PDF/PowerPoint exports and email subscriptions — a benefit of it being Microsoft-certified. Exports capture the chart as it appears on screen, including the current selection and any Top N filtering.
