chartTheme: Create A Chart Theme

In quantmod: Quantitative Financial Modelling Framework

Description

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

Usage

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

Arguments

theme	name of base theme
...	name=value pairs to modify

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.colforeground color

• bg.colbackground color

• grid.colgrid color

• borderborder color

• minor.tickminor tickmark color

• major.tickmajor tickmark color

• up.colup bar/candle color

• dn.coldown bar/candle color

• up.up.colup after up bar/candle color

• up.dn.colup after down bar/candle color

• dn.dn.coldown after down bar/candle color

• dn.up.coldown after up bar/candle color

• up.borderup bar/candle border color

• dn.borderdown bar/candle border color

• up.up.borderup after up bar/candle border color

• up.dn.borderup after down bar/candle border color

• dn.dn.borderdown after down bar/candle border color

• dn.up.borderdown after up bar/candle border color

Value
