- What Grafana version and what operating system are you using? 11.1.3 - **What** are you trying to achieve? Pass a group value to another panel - **How** are you trying to achieve it? Via setting variable and datalinks - What happened? Variable is not set - What did you **expect** to happen? Variable is set, target panel updates data based on the variable value - Can you copy/paste the configuration(s) that you are having problems with? No - Did you receive any errors in the Grafana UI or in related logs? If so, please tell us **exactly** what they were. No I have a Bar Chart based on SQL query. It groups data by “product” field and calculates count. ![image](https://us1.discourse-cdn.com/grafana/original/3X/5/b/5b3ade5f99c95fdc68d6ad42a5866a2a803f0bed.png) I have another panel (table view) - I’d like to click on a bar and show details in that panel for a selected “product”. ChatGpt suggested to use Custom variable and a Datalink with a placeholder in a form of var-product=${\_\_field.labels.product} but it does not work, variable is not set. I also tried different placeholders but with the same result. If I use \_\_value.raw, variable is set correctly but to the Count value. Is it possible to achieve what I want? How can I set my variable to a group value- those ones that are painted on an image above 🙂 ? ---

> [@yosiasz](#): > > bar chart click event in grafana doc Sorry , not sure what you mean by that? Here is a doc how to set data links if you asked about that > **[Configure data links | Grafana documentation](https://grafana.com/docs/grafana/latest/panels-visualizations/configure-data-links/)** > > Configure data links to create links between dashboards and link to external resources That’s what I see when I click on the bar: ![image](https://us1.discourse-cdn.com/grafana/original/3X/3/7/3765c2779e805e5990aa177ac476f5e283cfb056.png) What I want to catch and pass to datalink is “Shared services” in this case. Each bar has a diff ManagementZone value. ---

Figured! Tried all possible placeholders and this one - ${\_\_data.fields[0]} worked! ---
