Population in countries bordering GermanyEdit

Wikidata query produces three columns - year, population size, and country name. This graph shows one line per country.

Default
tab
Stringoptional
Tabletable

Data page name on Commons, without the Data: prefix. The table should contain xField column, like year or date, and one or more series columns to plot. If tabletype parameter is set to "query", this value is the query.

Stringrequired
X axis typetype

Type of the x axis - time (e.g. "2015-10" or "2013-03-08"), year (integer, but treated as a year), linear (numbers), ordinal (anything).

Default
year
Stringsuggested
X fieldxField

Id of the data column that contains values for the X axis. If type=year, xField is also "year" by default.

Stringrequired
Seriesseries

If each line is represented by a separate column of data (or if there is only one column), list of the data columns to show as lines. Must be in quotes, and listed by field IDs if coming from a .tab page: "field1", "field2", "field3".
