may have fixed it. used rtl_433 set only to 915mhz to time interval of WH32B ... it is 1 minute between packets. atlas is much faster than 1 minute. need to add time for rtl_433 finding "minimum detection level based on noise" for each frequency hop. set "hop_interval 120" in rtl_433.conf. set "archive_interval = 300" in weewx.conf. 300 sec = two times 120 ... one for atlas and one for WH32B plus an extra minute for "minimum detection level based on noise". This fixed the problem. Now weewx draws lines not points when plotting. I assume this means there are no nulls in archive records due to archive interval expiring faster than complete packets arriving.
next question: should have in weewx.conf "record_generation = hardware" or "record_generation = software" ?
