Arguments

dat

a data object (a matrix, a data frame or a factor array)

xvar, yvar

objects of class "formula" (or one that can be coerced to that class): x,y coordinates of the given data.frame colnames, e.g. xvar = ~xAxisName; yvar = ~yAxisName. xvar, yvar only needed for the data.frame data input.

series

an "formula" object: Associates the levels of variable with symbol color, e.g. series = ~groupName

size

an array of html widget width and height(either numeric pixels or percentage could be accepted): e.g. size = c(1024, 768).

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: Echart + eTitle(title="main title", x = "left", y=10)

legend

logical whether the legend widget show or not, default is TRUE. you can modify legend widget after chart has been generated, the legend position and legend orientation are available at present. Echart + eLegend(show = TRUE)

legend.x, legend.y

legend.orient

an element of c("horizontal", "vertical"), default is "horizontal" you can modify legend widget after chart has been generated: Echart + eLegend(orient = "vertical")

toolbox

logical whether the toolbox widget show or not, default is TRUE. you can modify toolbox widget after chart has been generated, the toolbox position, toolbox element and toolbox orientation are available at present. Echart + eToolbox(show = TRUE)

toolbox.orient

an element of c("horizontal", "vertical"), default is "horizontal" you can modify toolbox widget after chart has been generated: Echart + eToolbox(orient = "vertical")

toolbox.x, toolbox.y

the xy coordinates of toolbox, 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 toolbox widget after chart has been generated: Echart + eToolbox(x = "right", y="top")

tooltip

"axis" option for trigger will show all the information of mouse; "item" option for tirgger will only show the given item information of mouse. you can modify tooltip widget after chart has been generated: Echart + eTooltip(trigger = "axis")

calculable

logical whether the front-end interactive chart will support the drag-recalculable feature. the size and calculable option can be setted after scatter chart has been generated through eOption: Echart + eOption(calculable = TRUE)

powers, precision

the precision and powers of value display setting. default: power = 2; precision = 2

dataview, mark, restore, dataZoom, magicType

logical variable whether the dataview , mark, restore, dataZoom or magicType tool in toolbox widget show or not, default is TRUE. you can modify toolbox widget after chart has been generated, the toolbox position, toolbox element and toolbox orientation are available at present. Echart + eToolbox(dataView = FALSE)

tooltip.formatter

the information formatter for tooltip widget, default is "<a>:<b><c>" for scatter chart. you can modify tooltip widget after chart has been generated: Echart + eTooltip(formatter = "<a><b>:<c>")

Note

You are recommended to use lazyPlot function for interactive chart option set through "shiny" server.
