Not a Problem
HI
In one variable statistics, with data
17, 17, 18, 18, 18, 19, 19
histogram shows only 2 bars, when there should be 3. Class rule is not working.
Files:
histoError.ggb
The same problem 
1 get 3 bars with your file
I also
So why I get only 2? What data I should send?
Please post a screenshot of what you actually get
I didn't explain the problem clearly enought. Data is age, so I would like to have classes
17<=x<18
18<=x<19
19<=x<20
so I set classes manually, and this doesn't work correctly
Salut Hannu,
hmm, try to set your "Width" from "1" to something like "0.9" or another number lower than "1".
Greetings

The convention for the last class is a≤x≤b
https://wiki.geogebra.org/e...
si las clases son
17<=x<18
18<=x<19
19<=x<20
los datos deben set 17.5,18.5,19.5
si los datos son 17,18,19 las clases deben ser
16.5<=x<17.5
17.5<=x<18.5
18.5<=x<=19.5
entonces empezar en 16.5 y ancho 1
