How to call Histogram ?

It's probably something stupid, but I can't get Histogram to work . I tried bunch of combos, lower case "h", input = ret, etc... It works fine without the Histogram line

I either get a "There is no attribute or namespace named histogram", or "There is no function named histogram" message. "libhistogram.dll" is in my C:\Program Files (x86)\VapourSynth\core64\plugins directory

Can someone please give an example of the syntax ? I couldn't find any documentation or examples

Code:
import vapoursynth as vs
import havsfunc as haf
core = vs.get_core()

ret = core.lsmas.LWLibavSource(source=r'E:\video.avi', format="YUV420P8")
#ret = core.std.Histogram(ret)
ret.set_output()
Thanks

Thanks!

Maybe the wrong thread to make a suggestion, but for many new users, I think if some simple examples were given in the documentation it would help. Not everyone knows how to read from the code

Certainly. Anyway, when documentation is too vague or nonexistent you can use this script:
Code:
import os
import vapoursynth as vs


core = vs.get_core()

filepath = "/path/to/somewhere"
filename = "vs_function_list.txt"

info = core.list_functions()

fn = os.path.join(filepath, filename)

os.remove(fn) if os.path.exists(fn) else None

with open(fn, 'a') as f:
    for line in info:
        f.write(line)
It will write a file you can search for reference on namespaces an function names.
From that file:
Code:
name: VapourSynth Histogram Plugin
namespace: hist
identifier: com.nodame.histogram
	Classic(clip:clip)
	Color(clip:clip)
	Color2(clip:clip)
	Levels(clip:clip; factor:float:opt)
	Luma(clip:clip)

I updated the documentation.
