Module:Graph:Chart/doc
Appearance
Usage
[edit]This module simulates {{Graph:Chart}} but with a lower post-expand include size. Use it on articles with large numbers of graphs or that are approaching the PEIS limit. It can also be used in other templates or modules.
Follow documentation for the main template, but replace {{Graph:Chart
with {{#invoke:Graph:Chart|
(note the extra vertical bar), and it should work exactly the same way.
