Span over several days

[nicolas-raoul]

I am investigating an anomaly that occurs around midnight.
Unfortunately, it seems that python-sarviz only allows me to select a single data file.
It also makes it difficult to compare with the previous day.
For instance, if the anomaly occurred on the 13th it would be great if I could make the charts show the data of sar12, sar13, and sar14.
Thanks! :-)
