Real-time monitoring > "find logs" button creates a new timeline instead of overwriting the old one

[asvdvl]

Steps to reproduce:

1. Go to https://topolograph.com/ospf-isis-monitoring
2. select time range
3. press the "Find logs" button more than 1 time

As a new user i expected that changing the settings would just overwrite the existing timeline and not add a new one, maybe this is the correct behavior i don't know
