Zabbix Graphs Show No Data When Data is Available in Latest Data

[leeman24]

I have an issue when I make a graph and Add Total Memory, it says that there is no data. I also have other details such as Available Memory and Used Memory which are working on the same graph.

If I go to Latest data, I can see values for all servers.

I have tried to remove and re-add the Total Memory key from the graph but the same issue persists.

zoom in to the latest hour. If the item is new and the graph time is big or doesn't include the current time, this can happen.
