1 Introduction

aesStyle is a big family to construct Echarts styling element objects. E.g., Echarts uses itemStyle heavily, and you can either use itemStyle function or directly build the itemStyle object by writing a list.

Inside an itemStyle list object, there are three types of elements:

  • atomic features
    • ‘color’, ‘borderColor’, ‘borderWidth’, ‘barBorderColor’, ‘barBorderRadius’, ‘barBorderWidth’, which you can directly assign values
  • object features
    • ‘lineStyle’, ‘textStyle’,‘areaStyle’, ‘chordStyle’, ‘nodeStyle’, ‘linkStyle’, which you can yield by aesStyle function family
  • mixed object features
    • ‘label’ and ‘labelLine’, which contains other object features, such as ‘lineStyle’, ‘textStyle’

2 Function Call

All the function names have two forms: small camel and lowercase_underscore (endorsed by Hadley Wickham). To be lazy, we also provide short forms as well (e.g., ll for labelLine).

How to build an itemStyle object?

First, build the low-level style element object.

styText <- textStyle(color='red', fontFamily='Arial')
styLine <- lineStyle(color='#fff', width=4, shadowBlur=5)

Then, build up higher-level style element objects.

lab <- labelStyle(show=TRUE, position='inside', textStyle=styText)

Finally, consolidate an itemSytle object.

itemStyle <- list(normal=itemStyle(lineStyle=styLine, label=lab),
                  emphasis=itemStyle(lineStyle=styLine, label=lab)
              )
