[Xymon] Zoom graphs not working

Hello,

I created a http monitor on one of my webserver that contains 10 http link. I noticed the 2 issues below.

1. The http graphs doesn't show in "Trends"
2. The graps shows when I go to "http" page but when I click on zoom, nothing shows up.

Does the issue has something to do with having 10 http link configured or something else?

Thank you.

Ray
