 Description   

If we configure a negative multiplier on a numeric (unsigned) item, we always get the same value: 18.45E.

The same works great with numeric float item.

The issue I have is that I want to graph both incoming and outgoing network traffic on the same graph, so I use a negative multiplier for the outgoing, so the graph will be reversed.

Until now, I used float item for traffic accounting (and the negative multiplier for outgoing), but, I hit bug ZBX-2272 (Item server02:net.if.in[eth0,bytes]] error: Type of received value [1264329667796] is not suitable for value type [Numeric (float)].
So, I tried to convert all these items to unsigned, but outgoing traffic doesn't work anymore with the negative multiplier.

This is a good space saving technique used extensively in Cricket with genDevConfig, Nagios, etc. Provides more information per graph. As you can add max + average on the same graph for both IN and OUT data.

This issue looks more like a request for being able to select which side of the X-axis item values should be shown on a graph (i.e., show the values mirrored or not). By introducing the possibility for selecting the side of the X-axis we can have both real (positive, not garbled) values in the database and nice graphs.

Indeed, I use negative multiplier as a work arround, having the possibility to choose the side of the X-axis would be a lot better.
