New default behaviour for tooltips during comparisons
philschoefer opened this issue · 1 comments
Feature request summary
Currently Polaris Viz renders the series name for tooltip labels. Each of the tooltip rows consists of the name of the series and the corresponding value at that point of the X-Axis.
This works well when comparing e.g. products:
However, as soon as one series is set to isComparison: true the output is lacking some information:
What day exactly had that amount of sales? In the tooltip we indicate that we're comparing against previous month data, but we never know what point in the past the displayed value is actually referring to. We also don't show that information in the X-Axis.
Rationale
Many places in the admin have worked around this limitation by creating custom tooltips that display the label of the activeIndex of the comparison data series instead. So instead of April 1-14 and Previous Period it would show the exact date for that specific data point.

Notebooks is about to hit this issue with ShopifyQLV2 introducing the COMPARE TO keyword: https://github.com/Shopify/core-issues/issues/47801
I think we should consider to update Polaris Viz tooltip default behaviour to switch into a different tooltip mode when isComparison is set on a series where the header disappears and instead of showing series names we display the label of the actual data point in the tooltip.
When this is implemented, we could also consider adding in the Trend indicator which is also commonly used where two values are compared against each other in a tooltip and currently needs to be custom implemented in every place we do comparisons in charts.
