TimeSeries Graph

Hi, I want to have multiple time series graph within a single dashboard, I want to have the data categorize as 30days, 7days, and 1 days. I am filtering out my query as below, with some additonal transformation. This will be same across the other 2 (7d and 1d), however when I try to choose this from 30days to 7 days for my second graph, my 30days graph get corrupted and only showing 7 days result. Is there any option to fix this issue

| where timestamp >= ago(30d)
