PC3D

One night while listening to music from the Heart of Space, I got an idea for combining two kinds of graping charts. I called it the PC3D for Pie-Column 3 Dimensional graph. I shared this idea with a friend up in Québec, Canada and he liked it. Does such a thing already exist and if so, is there a program that would utilize it? I have tried to combine such concepts with Excel and Word, but to no avail.

The Column part could represent income or expenditure, while the pie on top of the column could represent what % of sources were coming or going. This system would take a 3D format as columns could be representations of different elements or companies, lined up according to years, next to each other, and even color-coded. The pie charts, again, would be right on top of each column. This would present both an economical way of presenting data as well as more detailed comparison of that data's percentages. —Preceding unsigned comment added by R3hall (talk • contribs) 18:36, 5 February 2008 (UTC) ~R3hall[reply]

I haven't seen that particular approach used. Pie and bar charts are more commonly combined to drill down within a particular category, e.g. Excel's bar of pie charts.[1] Maybe I'm not understanding it properly, but a stacked bar chart[2] seems to convey the same information as your idea, and is even more economical. -- Avenue (talk) 21:48, 6 February 2008 (UTC)[reply]

Just imagine a column. Now imagine that you are going to peer down, bird's eye view, on top of that column. You see a pie chart right on it. Again, Image a set of columns, each with a different color (representing party/year) and height (amount). Then right on top of each is a pie showing what percentage make up those amounts. Does this help? ~R3hall

I think I've seen such visualization in one of the blogs of "junk charts" that I used to follow, but I can't find it. I believe that it has been used for showing mutual fund return & asset allocation at the same time & possibly been used in other popular media. The verdict on the blog was that it wasn't very usable. Pie charts, in general, aren't usually the best vehicle for conveying percentages (since we're not so good at judging the size of the pieces). --Karnesky (talk) 18:44, 15 February 2008 (UTC)[reply]

Matrix chart

What about Matrix charts? —Preceding unsigned comment added by 60.234.150.148 (talk) 11:05, 17 March 2008 (UTC)[reply]

Anatomy of a Chart

I came here looking for the terms describing the different parts of a chart, and did not find them. Is there a particular name for the labels and numbers on the X and Y axes? Is there a name for the "graph paper"-like rulings in the background of some charts? Stuff like that. —Preceding unsigned comment added by 71.174.229.241 (talk) 02:02, 30 August 2008 (UTC)[reply]

Not a bad suggestion I think, so I had a go at creating a "features of a graph" section. Difficult to balance the generality of this page with the specific features of some charts, but I hope what I've written provides a start to a useful section on the anatomy of common chart features.

The scope of this article

I have been altering the scope of this article in the past months, since the 23 june 2008 version of this article. By then this article was then focussed on:

quantitative charts and plots, and
"Plotting" was redirects here

The article more or less stated, that qualitative charts was a separate chapter. It had a notification:

Usage note: many information graphics or diagrams include the word "chart" in their name but are covered in those other articles (e.g., flowchart, org chart, smith chart).

Now I made some changes, which has influenced the scope:

first some wikification, and
altered scope to both qualitative and quantitative charts

Now I created a separate Plot (graphics) article, where the "plotting" is redirected now. In this article now all references to these plots can be removed. Then this article will focuss on qualitative and quantitative charts. -- Marcel Douwe Dekker (talk) 11:50, 15 October 2008 (UTC)[reply]

Thanks for this. Good improvements. I think the distinction between a plot and a graph is vague and there's likely to be some difficulty keeping them separate in the future. Off to a good start though. I suggest the links between Chart and Plot (graphics) be made more obvious, less one think information on Bode plots or box and whisker plots is missing. LightYear (talk) 22:17, 19 October 2008 (UTC)[reply]

Thanks. This is indeed (just) a start. There is still a lot of work here. I share your concerns and agree to make a more obvious link. Now I added an extra gallery with "common plots" as a start. Do you think this will do the job? One other question for you is, if you also noticed that the English Wikipedia isn't offering an overview article about the graph? Off cause there is the disambig page, and the graph of a function page. But I think a graph of a function is just one general type of graph. You are right, that the distinctions between plots, graphs and charts are vague. I think there is a job here for Wikipedia to explain this some more!? -- Marcel Douwe Dekker (talk) 23:01, 19 October 2008 (UTC)[reply]

disambig nautical chart removed

I removed the "disambig nautical chart" on top of the page. This is a typical item allready mentioned in the chart disambig page.

These image types doen't even classify as "specific type of charts" as was explained in the diasmbig page see here. Typical examples of charts are those explained in this article.

So changed this in in the disambig page calling nautical charts a type of map, see here.

Copied and pasted from various Wikipedia articles

This article or section appears to have been copied and pasted from various Wikipedia articles, possibly in violation of a copyright. This might have occurred in the period of Sept-Oct 2008, when I rearranged the current article.

I apologize for all inconvenience I have caused here, see also here. If you would like to assist in improving this article, please let me know. I can use all the help I can get. Thank you.

-- Marcel Douwe Dekker (talk) 14:21, 13 October 2009 (UTC)[reply]

I checked but there don't seem to be sections copy/pasted from other articles here, so I removed the copypaste-template -- Mdd (talk) 19:08, 31 October 2009 (UTC)[reply]

References removed

I just removed a first reference, see here, the source http://forexcharts.ws doesn't seems like a reliable source, and I can not find this statement here in that source.

And I removed a second reference here which seemed to be added as decoration about at year ago, see here. An additional reason is that the particular source doesn't seems that notable. -- Mdd (talk) 12:56, 17 November 2009 (UTC)[reply]

Quotes about charts

Interesting quotes about charts:

"What Is a Chart? A chart is a visual representation of data. The data are represented by symbols, such as bars in a bar chart, lines in a line chart,, or slices in a pie chart. By depicting this data as graphical. symbols, patterns or trends in the data can be more easily identified. Data charts often are called graphs"
- In: Cary Jensen, Loy Anderson (1992). Harvard graphics 3: the complete reference. p.413

"A chart represents the current data in a table. If the table is updated, the chart will reflect the change. A chart can represent a selected set of records in a table as well as the entire table."
- In: Scott Hutchinson, Larry Daniel (1995). Inside ArcView. OnWord Press. p.743.

"To understand the logic behind charting, you must begin by recognizing that a chart represents a graphic picture of past market behavior. This is true regardless of the chart methodology utilized - bar, point and figure, reversal, and so on. Those graphical representations achieved are the consequences of market participation taking a position in the market. Thus the chart represents a giant up-to-the-minute opinion poll, recording every single bit of information - fundamental and technical - utilezed by each market participant in making a market decision."
- In: Leo Melamed (1993). Leo Melamed on the markets: twenty years of financial history as seen by the man who revolutionized the markets. John Wiley and Sons p.15

Comment: Allthough Melamed talks about specific charts used in stock exchange the idea of talking about a chart methodology is interesting. Looking further into "chart methodology" could be interesting.

More quotes:

"Whatever a chart represents, be sure it helps you understand your data more readily while portraying the data simply and attractively".
- In: Kenneth C. Laudon et al. (2001). Microsoft Office XP. ‎

"A chart represents parts of a whole."
- In: Philip A. Koneman (1999). Microsoft Excel 2000‎.

"... such a chart represents an attempt to depict some elements of the formal organization."
- In: Joseph August Litterer (1963). Organizations: structure and behavior. p.32

Comment: This is a nice reminder that not all charts a quantitative... like the organizational chart.

"A chart represents a part of the earth's surface."
- In: World fishing, Volume 11‎, 1962. p. 34

Comment: And this a reminder that nautical charts are also called just charts. The overview section of this article is allready commenting on this.

It might be a good idea to start a Wikiquote article about charts, which can make some distinction in the quotes. One extra quote about the need for charting:

"Everyone has data of one kind or another, whether on paper, in the computer, or just in the mind. We often need to know the significance and properties of the data, or to be able to compare different parts of it against other data sets. One of the simplest aspects of data display is the production of charts. This is where you would want to put your data into a graphical form to show relationships and comparisons between sets of values".

Chart Software

I have added a new section - Chart Software - and requested a new article to be created "Comparison of Chart Software" in a similar vein to how the Mindmap page references Mindmap#Tools being List of mind mapping software. — Preceding unsigned comment added by 61.88.45.5 (talk) 02:15, 8 March 2012 (UTC)[reply]

Support the new article. Lots of similarly useful articles on Wikipedia. Will also allow the arbitrary list of chart software in this article to be removed and replaced with a link to the new article. I don't support the arbitrary list so much. LightYear (talk) 22:34, 11 March 2012 (UTC)[reply]

maybe add http://draw.io/ website? // IQ.kz (talk) 10:19, 10 November 2015 (UTC)[reply]
