Templates

Template is the config that allows you to control each parameter of Chart.

Why to use templates

Template is the powerful tool to control hidden parameters of Chart, e.g. rounded corners of Bar chart. Another common use case is themes, if you have Light and Dark themes in your product or you have different products with different brand assets — templates are made for you.

What is template

Template is the JSON configuration. By default you always have Default template that could be edited. Below you can find the example of template with comments.
