Using Python version 3.8.2 and PySide2 version 5.14.0, time chart call tree would not expand the tree to the result. Fix by using setExpanded(). Example: $ perf record -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.034 MB perf.data ] $ perf script --itrace=bep -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py perf.data.db branches calls 2020-06-26 15:32:14.928997 Creating database ... 2020-06-26 15:32:14.933971 Writing records... 2020-06-26 15:32:15.535251 Adding indexes 2020-06-26 15:32:15.542993 Dropping unused tables 2020-06-26 15:32:15.549716 Done $ python3 ~/libexec/perf-core/scripts/python/exported-sql-viewer.py perf.data.db Select: Charts -> Time chart by CPU Move mouse over middle of chart Right-click and select Show Call Tree Before: displays Call Tree but not expanded to selected time After: displays Call Tree expanded to selected time
