Arguments

dat

title.x, title.y

the xy coordinates of main title, besides the excat exact pixels value, x accept c("left", "right", "center") and y accept c("top", "bottom", "center") as legal input. you can modify title widget after chart has been generated: barEchart + eTitle(title="main title", x = "left", y=10)

tooltip

logical whether the tooltip widget for front-end interactive chart show or not. default is TRUE. you can modify tooltip widget after chart has been generated, the tooltip trigger and tooltip formatter is available at present. barEchart + eTooltip(show = FALSE)
