I'm using Grafana v8.3.4 (a551d74b11)

I've a dashboard with many variables (filters). One of those is for exemple TransactionType.

I would like my charts to filter on click.

For example with a pie chart using TransactionType, I want to filter the TransactionType variable ,when I click in one of the element of the pie chart, by this element.

The closest feature I found is to use data link.

So far I tried in the pie chart the two data link there after. The syntax is OK but the effect is not doing what i’m expecting.

a)

/d/${__dashboard.uid}/${__dashboard}?var-TransactionType=${__series.name}

For this one the data link apply the filter on TransactionType but clear all the other filters variables, even clear the All, so the dashboard is in error.

b)

/d/${__dashboard.uid}/${__dashboard}?${__all_variables}&var-TransactionType=${__series.name}

this one apply all filters first then add the TransactionType filter but, it keep the previous All value, so the filter become All + value, that don’t work, the dashboard is in error too.

==> Is there a way to keep all the existing variable filter unchanged and replace the value for one variable filter ?
