hal-histogram works for pins only but a pin is provided for
measuring each thread time (in clocks).
Example:You will have to adjust the minvalue,binsize,nbins either
interactively or from the command line.

Example:
$ hal-histogram servo.thread.timeinteractively or from the command line.
Ref:
$ hal-histogram --help
Usage:
hal-histogram --help | -?
or
hal-histogram [Options] [pinname]
Options:
--minvalue minvalue (minimum bin, default: 0)
--binsize binsize (binsize, default: 100)
--nbins nbins (number of bins, default: 50)
--logscale 0|1 (y axis log scale, default: 1)
--text note (text display, default: "" )
--show (show count of undisplayed nbins, default off)
--verbose (progress and debug, default off)
Notes:
1) LinuxCNC (or another Hal application) must be running
2) If no pinname is specified, default is: motion-command-handler.time
3) This app may be opened for 5 pins
4) pintypes float, s32, u32, bit are supported
5) The pin must be associated with a thread supporting floating point
For a base thread, this may require using:

No-- hal-histogram provides input pins which must be connected by hal signals
to appropriate hal output pins. You could modify the source code to
change certain parameters to pins for your purposes.
An alternative method uses hal-histogram in conjunction with the
hal latencybins component that is used by the latency-histogram program.
(The latency-histogram program is not usable when linuxcnc is running).
Thisi latencybins component provides a hal pin for latency, and it
can be connected to hal-histogram using the method shown in the image.

is there a workaround to make Hal-Histogram work with parameters, like
Halmeter or Halscope can?
