Using time bins from heatmap as timerange in data link graph

Grafana Data Links
1

Hi all,

I have a heatmap where I would like to make a drill-down chart using a data link. The idea is to be able to click the link per square, and it will bring you to a different dashboard, where the minimum and maximum time of the bin is the timerange.

In my data, the bins are separated into groups of 5 minutes:

The heatmap graph works:

So how come the URL is empty for both variables
${__value.time} and ${__data.fields.time} when inserting into the data link? And what is the difference between the two?

Furthermore, any suggestions on how to get not only the time value but also get the value at the end of the time bin (start + 5 minutes)?

Very excited about making this happen, thank you for the help.

@fllh Have you found a solution?
I would also like to know if this is currently even possible.

I do this from my heat maps so that I can link from any cell.

https://myacctount.grafana.net/d/be3ghs188n4e?var-FROM_DB=HM_DEVS&var-DEVID=${__field.name}&var-TIME=${__data.fields.TIME}

Where the DEVID value is gets set to the Y-axis name on the heatmap and the TIME value is pulled from the cell that I click on so that the next dashboard can drill into that specific time and use the DEVID to perform a more focused query for that specific device at that specific time.The FROM_DB=xxx is just an ID I use so that the target dashboard know which source dashboard the request came from so that I can perform special SQL templating to handle many sources in a single target dashboard.
