Search Query to always display specific row help pls

I have this search query sourcetype="CurrentWeatherSGMap" Message="Yishun" | eval Description=case(current_summary="Rain", "Poor" ,current_summary="Cloudy", "Good", current_summary="Partly Cloudy", "Excellent") | chart dc(Description) AS Rain over date_hour by Description

How can I always display a row of poor(yellow colour) on every column ?

Something like this: It displays all the poor then stack with fair.
