Alert from NRQL: colorize graph in red when violation

I just set up an alert based on a NRQL query. I’m also displying the graph on a dashboard.
Now I just want the graph to get the red color when there is an alert violation.
How can I achieve that ?

Thanks in advance,

Hi @erwandf - You can achieve this by using a Billboard chart. Set the warning and critical values to change it yellow and red.
