wxParaver is a trace-based visualization and analysis tool designed to study quantitative detailed metrics and obtain qualitative knowledge of the performance of applications, libraries, processors and whole architectures.
When computing the aggregate statistics of an histogram showing the "% Time", the Average statistic is computed differently when there are no states for that object:
You can see that the states 1 and 2 show the same value in Total and Average but not for 3. The "% Time" in the state 0 and 1 in CPU 0.1 should be 0 % not "-" (presumably null), so the Average values are divided by 2 instead of by 1.
I am unable to find any option to make Paraver show a 0 instead of converting it to null but I'm suspicious that this behavior is not intended in any case anyway.
Additionally, catching this with a large number of objects will be hard for the naked eye (when showing the totals only). As safety, could you also add the N being used to draw the average and the other statistics?
