Extension talk:Graph/Demo

From mediawiki.org


Have suggested some improvements here [1]

This is exceedingly useful. I just need to be able to pull the what colors correspond to what ranges of numbers out of the map. An example is here [2]. And than I can start creating bunches to add to Wikipedia. Doc James (talk) 23:53, 23 July 2015 (UTC)Reply[reply]

This has been resolved with Vega 2.0. --Yurik (talk) 02:54, 24 January 2016 (UTC)Reply[reply]


The "Using API" graphs don't load at all for me in Firefox 42, even after disabling NoScript. Nemo 22:54, 16 December 2015 (UTC)Reply[reply]

Nemo_bis, There was an issue with caching, should be working now. Please double check. Thx! --Yurik (talk) 02:54, 24 January 2016 (UTC)Reply[reply]

Graphs are not the same in previewing mode and reading mode[edit]

The following graph :

is supposed to have a "mouseover" functionality; actually, this functionality works only when previewing the graph. Automatik (talk) 22:08, 1 February 2016 (UTC)Reply[reply]

Automatik, you need to enable it with "mode=interactive" (I fixed it above). You might also be interested in commenting on phab:T124254 - to make all graphs load dynamically on desktop. --Yurik (talk) 11:37, 2 February 2016 (UTC)Reply[reply]
Thank you Yurik! I suscribed to the phab task. Automatik (talk) 22:16, 2 February 2016 (UTC)Reply[reply]

Use of parser functions in "graph" tags[edit]


It seems that we can not use the parser functions —like {{NUMBEROFARTICLES|R}}— in <graph></graph> (a few weeks ago, it was possible):

Is there a way to use them? If not, could it be the case? Automatik (talk) 15:43, 6 March 2016 (UTC)Reply[reply]

Automatik, fixed above - use the {{tag:graph| {...} |mode=interactive}}. In general, I would advise to put graphs into their own templates like here. --Yurik (talk) 15:55, 6 March 2016 (UTC)Reply[reply]
Automatik P.S. Note that it seems some of these graphs do not exist on mediawiki, that's why it fails. Check it by changing :graph to :code. --Yurik (talk) 16:13, 6 March 2016 (UTC)Reply[reply]
Yurik, I do not understand, it worked a few weeks ago on fr.wiktionary (wikt:fr:Discussion Wiktionnaire:Statistiques#graph), now it doesn't work, neither with {{#tag:graph| {...} |mode=interactive}} or without (like before). Seems strange. Automatik (talk) 16:30, 6 March 2016 (UTC)Reply[reply]
Automatik, yes, my apologies, I thought I fixed all the cases before turning off template expansion. I had to disable the expansion of the templates inside the <graph> tags because it made other code much slower and more complicated. The template expansion only works if you use the {{#tag:graph|...}}, just like all other tags like <syntaxhighlight> and other. When you use the #tag:graph, make sure to always add a space between two } }. Also, if you ever need to use a pipe | symbol for the graph itself, use the {{!}} instead. Thanks!--Yurik (talk) 17:10, 6 March 2016 (UTC)Reply[reply]
Yurik: thank you. For information, this and this seem inconsistent: where is the main version of the template PageViews_graph? — Automatik (talk) 19:16, 6 March 2016 (UTC)Reply[reply]
Automatik, thx, updated. --19:40, 6 March 2016 (UTC)Reply[reply]

Graphs broken[edit]

Graphs in Using_RESTBase_API section seems broken.--Eloy (talk) 17:48, 20 April 2016 (UTC)Reply[reply]

Eloy, there is a graphs' bug that causes invalid images after some time if the graph uses time-based function. The pageviews api call uses last N days, thus the range changes every day. I will need to fix it once i figure out what is the root cause. --Yurik (talk) 00:30, 21 April 2016 (UTC)Reply[reply]


I think it would be better if graph's JSON were uploaded to Commons. Or am I wrong?--Eloy (talk) 17:49, 20 April 2016 (UTC)Reply[reply]

Eloy, sure, it would be much better to share graphs and modules rather than copying them to each wiki by hand. There is a number of proposals for that, such as shadow namespaces, etc. It will be a long way to get there though :(. --Yurik (talk) 22:42, 20 April 2016 (UTC)Reply[reply]

Lua modules?[edit]

Is there a way to construct grpahs with a module? I think this could be linked to Wikidata, also.--Eloy (talk) 17:51, 20 April 2016 (UTC)Reply[reply]

Eloy sure, Template:Graph:Chart does exactly that. You can also use a {{#tag:graph| { ...graph definition... } }} approach.--Yurik (talk) 22:40, 20 April 2016 (UTC)Reply[reply]


@Yurik: is it possible to draw bar/pie/line charts using data from SPARQL? It works with the maps so i guess it is possible, but i could not figure how it should be done. --Zache (talk) 10:26, 10 October 2017 (UTC)Reply[reply]

@Zache: , sure, sparql can be used as another data source. some examples. Also, Template:Graph:Population_history can pull data from Wikidata. --Yurik (talk) 17:42, 10 October 2017 (UTC)Reply[reply]
@Yurik: Thanks! Graph:Population history was something what i was searching! I modified the idea and copied it to the d:Wikidata:Wikidata_in_Wikimedia_projects#Maps_and_graphs --Zache (talk) 14:02, 11 October 2017 (UTC)Reply[reply]


@Yurik: Do you think that it would be possible to translate json-stat formatted data to graphs directly in Vega or do i need to parse it using Lua or convert it to some simpler format before i store it to wiki?

Example code for parsing

--Zache (talk) 13:30, 21 November 2017 (UTC)Reply[reply]

@Zache: in theory it should be possible to process many common types of data, like the one you have, but it might get very tricky. It will be a whole bunch of transformations, mostly lookup transformations (and possibly various groupbys, like facet), to convert an array of elements to something else. I got a bit lost in the code - it seems you have a bunch of lookup tables, and somehow convert some set of data into some other set, but I couldn't grasp the exact conversion. And yes, in the worst case, you can dynamically generate the graph tag using Lua. But obviously it won't be as easy to manage. --Yurik (talk) 21:53, 22 November 2017 (UTC)Reply[reply]

Any examples of use on English Wikipedia?[edit]

Is this extension enabled on English Wikipedia? Can you point me to some examples of this being used on Wikipedia? Even if just on some user pages.

I rarely check my mediawiki.org watchlist. So, please ping me in your reply. {{ping|Timeshifter}}

Thanks in advance. --Timeshifter (talk) 20:12, 25 December 2017 (UTC)Reply[reply]

@Timeshifter: - about 3500 pages use it. Some are much more interesting than others: [3], [4]. --Yurik (talk) 20:34, 25 December 2017 (UTC)Reply[reply]

Unindent. Thanks! I have not been looking at my email for a few days. So many questions. Just a quick note for now until I have more time to look at this. This stuff is so advanced. I know next to nothing about wikidata. And this is all Greek to me:

{{Image frame
|content={{Graph:US Map state highlight | table=Bea.gov/GDP by state.tab}}
|caption=Map of U.S. states by GDP in million [[U.S. dollars]].

It is from List of U.S. states by GDP. --Timeshifter (talk) 05:28, 29 December 2017 (UTC)Reply[reply]

Timeshifter: heh, the actual graph is much worse ;) w:template:Graph:US Map state highlight --Yurik (talk) 06:22, 29 December 2017 (UTC)Reply[reply]
I see what you mean! What about the easier static stuff? Can you link to some examples on Wikipedia? Are there help pages on Wikipedia?
No need to ping me. I cleared out my watchlist, and set preferences to email me when anything on my watchlist (like this talk page) is changed.
It is a shame that there is not a single combined watchlist for all Wikipedia.org, Wikimedia.org, and mediawiki.org projects. So much more work would get done on Mediawiki, Meta, etc.. I only regularly look at my Wikipedia and Commons watchlists. --Timeshifter (talk) 23:04, 29 December 2017 (UTC)Reply[reply]
See Extension:Graph - good links there. --Yurik (talk) 01:24, 30 December 2017 (UTC)Reply[reply]

Wikidata integration[edit]

@Yurik: I'm trying to think of ways some of these graphs could be turned into useful properties for Wikidata. Any ideas come to mind? NMaia (talk) 01:41, 6 May 2019 (UTC)Reply[reply]

NMaia hehe, depends on what you are trying to achieve. It might make sense to have some sort of a popup on some properties like weather and population history (if available), and those have already been mostly done, but I can't think much beyond that... I would have to dig deep into wikidata :) --Yurik (talk) 01:46, 6 May 2019 (UTC)Reply[reply]
I was thinking of using a map like this on items such as Brazil–Suriname relations (Q15432031), as a more elegant way to show this relationship than locator map image (P242) with an image. The problem is that for small countries, a small and zoomed out map like that wouldn't be super useful. NMaia (talk) 01:50, 6 May 2019 (UTC)Reply[reply]
Ah yes, that's totally doable -- that's actually why i created that example to begin with. Would be a fun project :) I would think the map shouldn't be its own page, but rather a template of sorts with a param specifying which regions to highlight. --Yurik (talk) 01:53, 6 May 2019 (UTC)Reply[reply]
@Yurik: Sorry, I couldn't parse your last sentence. What did you mean? NMaia (talk) 03:30, 6 May 2019 (UTC)Reply[reply]
sorry i meant map, not relation (not sure where that came from. E.g. there shouldn't be one page per different map, but rather a generic template that you can give a wikidata id or a few country codes and it will draw it properly. --Yurik (talk) 03:32, 6 May 2019 (UTC)Reply[reply]


In the Timeline / lifeline example, what format are the timestamps for dates in? 

For example, George Washington's birth (February 22, 1732) is represented as "-7506057600000", and death (December 14, 1799) as "-5366196000000" --Owencunn (talk) 23:40, 12 July 2021 (UTC)Reply[reply]

Those timestamps are in Unix time, measured using milliseconds instead of seconds (à la JavaScript):
new Date(-7506057600000).toUTCString() === "Fri, 22 Feb 1732 08:00:00 GMT"
new Date(-5366196000000).toUTCString() === "Sat, 14 Dec 1799 06:00:00 GMT"
