RRD Graphs: System: Throughput: Incorrect max when using "inverse" style

[tristano]

Using 1.2-BETA-2, the Throughput graph shows maximum out values as negative, unlike the Traffic RRD graphs where all values are given as absolute values (in spite of their representation as negative on the graph). This results in the maximum value being incorrect like so:

| | maximum | average | current | period |
| in | 4.36 Mb/s | 0.15 Mb/s | 0.04 Mb/s | 275.03 MB i |
| out | -24.83 kb/s | -164.24 kb/s | -42.41 kb/s | 295.62 MB o |
| totals | 8.72 Mb/s | 317.03 kb/s | 84.87 kb/s | 570.65 MB t |

In this case the average out is "greater" than the maximum out because of the negative numbers.

EDIT: For some reason the text in the table above is white…?

no idea as of yet, I will have to look into it.
