Simple test plan to show the missing graphs

The scaling of the bars/lines in the components Aggregate Graph/Response Time Graph seems broken. While the numbers are shown correctly, no bars can be seen (probably happens when numbers are smaller than 1000 ;))

This is due to a small change to update our usage of Java APIs to a more modern style, where we changed the rounding mode to allow rounding down to zero, which would break the scaling.

    No Graphs displayed in Aggregate Report/Response Time Graph
    
    Make sure, that we scale away from zero (which is in our case mostly up).
    Otherwise we might end up with a scaling factor of zero, which would
    result in really small images.

OP wrote on mailing list, that the graphs work again in nightly build.
