I need to draw cpu usage of some processes with subsecond resolution. Currently, this fails with 3.9.7:

st ~/guider (master) $ python2.7 guider/guider.py top -g Xorg -i 0.1 -R 10s -o .

   _____       _     _
  / ____|     (_)   | |
 | |  __ _   _ _  __| | ___ _ __
 | | |_ | | | | |/ _` |/ _ \ '__|
 | |__| | |_| | | (_| |  __/ |
  \_____|\__,_|_|\__,_|\___|_|  ver.3.9.7_201227 on python_2.7


[ERROR] wrong value with -i option, input number in integer format
st ~/guider (master) $ 

Tested on Ubuntu 20.04.1 VM.

Subsecond interval is not supported in Guider top mode because of overhead :)

If you want to see detailed task activity, You can use rec and draw command.

# ./guider.py rec -s -R 10s
# ./guider.py draw guider.dat -q TIMEUNIT:ms

If you don't use -q option, It will draw time slices in default ns unit.
