- What are you trying to achieve?
Use data link in a pie chart to filter a dashboard on one variable when there is multiple variables.
- How are you trying to achieve it?
So far I tried in a pie chart with two the data link there after.
The syntax is OK it’s the effect that 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 + the 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 ?
