Tooltip ignore filter

Hi all,

I have created a scatter plot that shows result vs average result, the plot is filtered for a single metric (average result uses a calculate() with all() to ignore filter).

Scatter plot looks like:

I would like to create a custom tooltip so that when the user puts the cursor over a single point a tootip showing a bar chart of all results for that point is shown i.e. I basically need a way to tell the tooltip to ignore the filter on the metric. 

Tootip should look like (ideally with the metric highlighted in some way)

Is this possible? I tried a few combinations of the calculate() and all() functions but I either end up with no results or a bar chart with identical results accross all metrics.

Any help appreciated
