Create A Chart Theme
Create a chart.theme object for use within chartSeries to manage desired chart colors.
chartTheme(theme = "black", ...)
theme |
name of base theme |
... |
name=value pairs to modify |
Used as an argument to the chartSeries family of functions,
chartTheme allows for on-the-fly modification
of pre-specified chart ‘themes’. Users can modify
a pre-built theme in-place, or copy the theme to a new
variable for use in subsequent charting calls.
Internally a chart.theme object is nothing more than a list of values organized by chart components. The primary purpose of this is to facilitate minor modification on the fly, as well as provide a template for larger changes.
Setting style arguments for TA calls via chartTheme requires the user to pass the styles as name=value pairs with a name containing the TA call in question. See examples for assistance.
Current components that may be modified with appropriate values:

bg.colbackground color
grid.colgrid color
