Create A Chart Theme

Description

Create a chart.theme object for use within chartSeries to manage desired chart colors.

Usage

chartTheme(theme = "black", ...)

Arguments

Details

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:

fg.col
foreground color
bg.col
background color
grid.col
grid color
border
border color
minor.tick
minor tickmark color
major.tick
major tickmark color
up.col
up bar/candle color
dn.col
down bar/candle color
up.up.col
up after up bar/candle color
up.dn.col
up after down bar/candle color
dn.dn.col

up.border
