setTheme: Set Theme Or Misc Aesthetics (color, background, animation,...

In madlogos/recharts2: An R Interface to ECharts3

Description

Set the entire theme of Echarts. You can use a pre-installed theme or define you own themes.

You can also set aesthetics of Echarts separately, including color, bgColor, animation, calculable, borderColor, borderWidth.

When an echart object is generated, you can modify it by setting aesthetics using %>%.

Usage

setTheme(chart, theme = c("asis", "default", "macarons", "infographic",
  "blue", "dark", "gray", "green", "helianthus", "macarons2", "mint", "red",
  "roma", "sakura", "shine", "vintage"), palette = "asis", bgColor = NULL,
  renderAsImage = FALSE, calculable = FALSE, calculableColor = NULL,
  calculableHolderColor = NULL, animation = TRUE, animationEasing = NULL,
  animationDuration = NULL, width = NULL, height = NULL, ...)

A modified echarts object

Self-defined Themes (UDT)

You can design your prefered themes using http://echarts.baidu.com/echarts2/doc/example/themeDesigner.html.

The UDTs in echarts are JS objects. You can write it in a list form and setTheme will parse it into JSON string for process.

A typical theme JS looks like:
{
color: ['#ff7f50','#87cefa','#da70d6','#32cd32','#6495ed'],
title: {x: 'left', y: 'top'},
legend: {orient: 'horizontal'}
}

You should write in the format below:
list(color=c('#ff7f50','#87cefa','#da70d6','#32cd32','#6495ed'),
title=list(x='left', y='top'), legend=list(orient='horizontal'))
