Template:Chart of NZ vineyard area by variety over time/doc

This template uses {{Graph:Chart}} to produce a stacked line graph of New Zealand's vineyard area by grape variety over time, using data from the annual reports available from New Zealand Winegrowers, the national industry organisation. Currently, they do not publish their statistics with an open license, so we can't use Wikidata-based tab-delimited files (yet... we're working on it!)

The colour values used in the chart are from {{BrewerColors}}, using Set3.

Usage

To include this chart in an article, simply place the following where you need it:

{{Chart of NZ vineyard area by variety over time}}

Which should produce a nice stacked graph:

New Zealand vineyard area by grape variety over time (1990–2020), in hectares.

  Sauvignon Blanc

  Pinot Noir

  Pinot Gris

  Chardonnay

  Riesling

  Syrah

  Cabernet Sauvignon

  Merlot

  Other varieties

The more than five-fold growth of Sauvignon Blanc plantings in the first two decades of the 21st century is evident, along with a similar rapid growth of Pinot Gris. Riesling, Merlot and Chardonnay are more or less unchanged or have declined slightly. A doubling of Pinot Noir has also occurred, and a tripling of the much smaller area of Syrah is countered by a corresponding decline in Cabernet Sauvignon.

You can optionally supply a named ref tag if the article already has a citation for the New Zealand Winegrowers reports and statistics page, otherwise one will be generated with the reference name "nzw-annual-reports". The ref is supplied as the first parameter, for example:

{{Chart of NZ vineyard area by variety over time | <ref name="refname"/>}}

The default citation will look something like this:
