While generating graphs on two hosts, if values on host A are missing the auto-scale min-max values on graph would crash and min value will go to 0, regardless the state latest data received by the zabbix server.

Still same data collectors same architecture and model, on some graphs will display and measure the min value properly. Have compared the values joined in the graph by latest data and are 1:1 on both sides where it works and the case where it does not. 

This issue seem to be only from version Zabbix 4.4.8
