Chart Themes

Source: R/chart_theme.R
chart_themes.Rd

The charting system ships with a set of built-in color themes inspired by chartthemes.com. Each theme controls candle colors, background, text, grid lines, and a 10-color palette (colorway) used to distinguish indicator lines.

Use ggplot2::set_theme() to apply or list themes.
