Extension:Graph/Demo/tr

Bu sayfa, Graph uzantısının neler üretebileceğine dair bazı örnekleri gösterir. Grafikler temel teknoloji olarak Vega dilbilgisi (belgeleri) kullanır. Vega ekibi, Grafiklerin kullanımını kolaylaştırmak için diğer araçlarda çalışıyor. Etkileşimli grafikler için bu eğitim yapı grafiklerini adım adım açıklayacaktır. Diğer grafik fikirleri için Vega örneklerine bakın.

Grafik şablonları
Grafikleri kullanmanın en kolay yolu, Graph:Chart (birçok Vikipedi'le4ir de mevcuttur) veya daha özel PieChart gibi önceden oluşturulmuş şablonlardır. Graph:Chart, çizgi, alan ve pie grafikler gibi birçok yaygın grafik türünü destekler:

More maps examples
This transcludes the page Extension:Graph/Demo/Map. The  tag's JSON data on that page specifies that its   data comes from a separate URL, Extension:Graph/Demo/RawData:WorldMap-iso2-json, that contains map data in JSON format. One of the elements in the  tag's JSON data specifies a highlight color for each country, in the format  :

Vega usually works with data in the format, so I created a helper Lua function to convert the data:

The Lua function's output is data in Vega's format:

Here is a more complex data processing example: MapTemplate is expanded with the data from Lua which takes it from the 2010 population distribution in the world (data based on UN data). To generate this graph, I use Lua module Graph:Utils's function  to extract the year 2010 column from the Extension:Graph/Demo/RawData:PopulationByCountryHistoric-csv page (in csv format), and pass that data as the first unnamed parameter to the MapTemplate graph. Additional optional parameter specifies that it should be scaled to 80%.



Note how the legend it wrongly positioned. That won't happen at lower scales.

Passing MediaWiki template parameters
If you're using a wiki page as a template, you can pass parameters to it, like any other MediaWiki template.

As an example, the graph specification in TemplateSample does not hardcode a fill color for ; instead it sets the fill color to. So if you visit that page or transclude it with no parameter, the graph fills with color  ; but if you transclude that page you can specify the fill color as the first template parameter.



Using a template for repeated graphs
This is very useful if you have multiple graphs of the same form: you can put the verbose graph JSON and additional repetive wikitext in a template and only pass the parameters to it that vary, such as title and values. See a sample of this approach.

Overlaying two types of data
Falkensee graph sample, see code.

Embedded directly with
This example is a  tag containing the graph JSON inside the current page.

Editing graph data
Editing JSON by hand is fiddly and prone to error. so you should use a JSON checker such as JSONLint or a JSON editor such as the Vega Live Editor to edit JSON before you copy and paste it into the wiki page. If the  tag's data is directly embedded in the page such as the example above, then if you use VisualEditor to edit the page you can directly edit graph data.
