Individual metrics can be switched on and off in the pull-down menu ``Metric Options''. By default all raw counter are off and all derived metrics are on.
The visualisation tool will highlight all results in red which it regards as poor and show those in light grey which are good. To us this is the key feature of HPMVIZ.
Important: Whether a result is good or bad depends on the precision of the code, which is directly obvious for a metric such as loads per load miss. Use the pull-down menu ``Precision'' to set ``single'' or ``double'' precision depending on your code.
