Hi all
Sorry for posting this question again. However, it is rather important
for my diploma thesis.
What does the x-axis represent exactly when '--time-unit=B' is used
together with 'massif' and 'ms_print'?
Or is this rather a question related to 'valgrind-developers' mailing list?
Please see for the intention of my question the previous post below.
Many thanks
Eric

Hi all
When using 'massif' it is recommended for short programs to use
'--time-unit=B' option since o/w no or hardly any output is shown using
ms_print for visualisation [1].
My question is now regarding the units of the x-axis.
As far as I have understood represents the unit the cumulated number of
bytes allocated and freed when option '--time-unit=B' is used.
Snapshots are taken for allocations and de-allocations, but also
in-between of them.
Since the value of the y-axis (Each vertical bar represents a snapshot,
i.e. a measurement of the memory usage at a certain point in time. [1])
and the value of the x-axis, which represents the cumulated number of
bytes allocated and freed, have a dependency to each other, how is it
possible that a parallel line to the x-axis is drawn in the graph [1]
since actually only a change in the heap usage should generate a forward
move on the x-axis.
Hope my problem was described somehow comprehensible.
Many thanks for your contributions
