Talk:Euler diagram

message: So no copyright problem. Also the diagrams included were creted by me using a Java based tool that I wrote.
So again no copyright problems.  —Preceding unsigned comment added by Robin48gx (talk • contribs) 17:28, 14 August 2005a

message: Are Euler diagrams and Venn diagrams only used for logic, or also for statistics? For a single variable, such as the color of cars, I can make a pie chart to illustrate which are more common. But for two variables, such as the brand and color of cars, it could be useful to draw diagrams that indicate the overlap, while the area of the graph is proportional to the market share. One might find that there are more black Mercedes, more blue Fords and more white Toyotas. Software such as OpenOffice Calc and Microsoft Excel can do pie charts, but not the overlapping kind. If they could, what would that kind of diagram be called? And what software can do such charts? --LA2 00:01, 14 September 2007 (UTC)
thread_title:  Relation to pie charts 

message: "Euler diagrams usually consist of simple closed curves in the plane which are used to depict sets. The spatial relationships between the curves (overlap, containment or neither) corresponds to set-theoretic relationships (intersection, subset and disjointness).
Euler diagrams generalise the well-known Venn diagrams which represent all possible set intersections available with the given sets.
The intersection of the interior of a collection of curves and the exterior of the rest of the curves in the diagrams is called zone. Thus, in Venn diagrams all zones must be present (given the set of curves), but in an Euler diagram some zones might be missing."
The above statement is not clear, I do not think one can generalize Euler's diagram as above.
If there is no relation between animals and minerals, obviously it cannot be represented.
If one was to say "food:minerals:animals that consume certain minerals" it would make sense and a Euler diagram can be drawn.  —Preceding unsigned comment added by 220.227.207.194 (talk • contribs) 12:04, 10 October 2008
@above, I am not sure but if you can select items specifically, get some demux...then the charts can be done for all possible combinations —Preceding unsigned comment added by 220.227.207.194 (talk • contribs) 12:19, 10 October 2008
more like the way we do it on a board. you have to have an attachment identifier
What I did like about Euler over Venn is that he sees it as "whole" and then parts of a whole, not intersections etc. so there is nothing like "a and b"
it is "b true in a" kinds.  —Preceding unsigned comment added by Alokdube (talk • contribs) 11:50, 14 October 2008
another noticeable thing is , that boolean algebra is closer to Euler diagrams.
for example a, a.b and a.b.c would be the 3 different zones , whereas one could call them 3 different events in logic circuits too  —Preceding unsigned comment added by Alokdube (talk • contribs) 11:03, 14 October 2008 (UTC)
thread_title:  clarification 

message: Many sites use Euler diagrams, or diagrams similar to those mentioned by "Relation to Pie Charts", but call them Venn diagrams. This blog postis a prime example. In fact, it could be used to explain Euler diagrams (I'm particularly impressed by the "dinosaurs etc. are only awesome if they are also ninjas" representation). 
To get back to the point at hand, the vast majority of Euler diagrams on the web are labeled as Venn diagrams, and most "Venn diagrams" are Euler diagrams, at least on humor sites. Should this be mentioned in the article? I find it very relevant and interesting. 65.96.201.130 (talk) 21:18, 19 October 2008 (UTC)

message: Tables and chairs have four legs and aren't animals.
I concur with the above, bearing in mind that not all tables and chairs have four legs. Also I have seen four legged stone tables. Also The black on dark blue is hard to see. Maybe another example would be more effective.  —Preceding unsigned comment added by 71.188.14.133 (talk) 21:23, 9 February 2009 (UTC)
thread_title:  Four legs 

message: Just thought I would point out that due to Euler's pronunciation (yu-), we should be saying "a Euler diagram" rather than "an Euler Diagram". I noticed this on the caption at the top of the page and I didn't know how to edit this, so I thought maybe someone here could. akokoza 00:46, 9 December 2009 (UTC)
replies: text: I've moved this to the bottom of the page. From my reading of the article Leonard Euler the correct pronunciation is "oy-ler" i.e. "oiler", not "you-ler". (This is the way I learned to say it ca 1960's.) Thus "An oiler" rolls off the American tongue much better than "A oiler". But I am open to argument. Bill Wvbailey (talk) 03:49, 9 December 2009 (UTC)

replies: text: The visuals depend almost completely on all of these simultaneiously: your browser, your settings for landscape versus protrait, your screen aspect-ratio (e.g. wide-aspect 1.78:1 (1366 x 768) versus boxier 1.38:1 (1450 by 1050)), your native screen resolution (e.g. 1450 x 1050 versus 1280 x 1024, or 1366 x 768 versus 1024 x 768 ), and the screen-magnification settings (e.g. the Windows browser the "100%", or whatever, magnifier at the bottom right). Just for an instance try changing the magnification -- the visual results are remarkably different. (I am simultaneously viewing this on three high-resolution, wide-aspect screens (Win 7, Vista) and an old boxier-aspect screen (Win XP). I changed the pixel size of the very large diagram from 1200px to 800px. I have noticed that under certain of these circumstances the drawings cover part of the text.

thread_title:  This page is a mess 

message: I changed the sentence in the introduction which read "They [Euler diagrams] include Venn diagrams." While this is technically true, I feel it will be confusing for nonmathematical readers (the most common kind) who may merely be looking for the most easy-to-understand definitions.  The first section of the article clearly explains the relationship between the two.  Comments?  --ChetvornoTALK 04:56, 11 October 2010 (UTC)
replies: text: Unfortunately, "nonmathematical readers" find many, perhaps most, of the mathematical articles on Wikipedia to be confusing. Whether that can be avoided without compromising accuracy is another matter, but someone coming here wanting to know, simply, "What is the difference between an Euler diagram and a Venn diagram?" is not going to find the answer without a huge amount of wading through long-winded examples. 86.186.54.115 (talk) 00:22, 26 February 2012 (UTC)
replies: text: Agreed, someone should rewrite the examples to remove the "wikipedia bloat" they've accumulated.  But it sure wouldn't help nontechnical readers for the intro to say that Euler diagrams "include" Venn diagrams.  In terms of method they are different.  And as I say, the first section explains the differences as well as the mathematical similarities pretty well.  Fortunately, no one is forcing the reader to go on to the examples.  --ChetvornoTALK 09:20, 26 February 2012 (UTC)

message: Can anyone write this in page in Swedish, please?  — Preceding unsigned comment added by 95.200.201.76 (talk) 18:36, 12 October 2012 (UTC)
thread_title:  In Swedish, please 

message: The text of the article (at 13 May 2014) states:
In the examples above, the Euler diagram depicts that the sets Animal and Mineral are disjoint since the corresponding curves are disjoint, and also that the set Four Legs is a subset of the set of Animals. The Venn diagram, which uses the same categories of Animal, Mineral, and Four Legs, does not encapsulate these relationships.
There is not example of a Venn diagram above, and in the absence of such an example, the statement "the Venn diagram ... does not encapsulate these relationships" reads as a general statement about Venn diagrams. That statement is certainly not true. It is trivial to create a Venn diagram that encapsulates the relationship that (some) 4-legged entities are a subset of the set of animals. It could be modified (by shading the currently non-empty intersection between "4 legs" and "mineral") to indicate that 4 legs is a wholly a subset of the set of animals.  — Preceding unsigned comment added by 130.123.96.22 (talk) 23:17, 12 May 2014 (UTC)

message: The Euler diagram seems to suggest that most dwarf planets are also considered minor planets, but that there is also a small number of dwarf planets lying outside the group of minor planets. However, I believe that all dwarf planets belong among minor planets. --Jan Kameníček (talk) 21:49, 31 March 2017 (UTC)
thread_title:  Dwarf planets in the Euler diagram 

message: In the Euler_diagram#Relation_between_Euler_and_Venn_diagrams section, we state "In the examples below, the Euler diagram depicts that the sets Animal and Mineral are disjoint..." That example does not appear below (it is at the top of the page). I think it could do with being inserted below the statement for illustrative purposes, but I'm going to leave that to regulars on this page since there could be a better way to rearrange this and it's probably best left to regulars around here.
