Removed bad values from database, how do I force graphs to update?

[Ivo Palli]

Some values that get send to Zabbix had an integer overflow and went hugely negative. This made the graphs, which are scaled, useless because all you could see is that one spike.

I removed the invalid data points from the database, but Zabbix is still showing the old graphs. How do I force a graph update?

Running Zabbix 6.4.8.

There could also be trends calculated based on your "wrong data". Depending on your graph length, it is drawn either on history or trends data...

You don't. The data is pulled from the data base when you refresh the page.
