Subject: [PATCH] Update threshold-alert.asciidoc (#4349) (#4485)

Hey, team, I'm sending this pull request because a customer asked about the bars from the preview chart. It was only showing 3 bars instead of 4, as the customer was expecting to see.  However, this is hardcoded and will only show the top 3.

(cherry picked from commit 992facd0b60027517b97aa16847047f2e574f216)
