In cosname/recharts: An R Interface to ECharts

Description Usage Arguments Note Examples

This function creates an HTML widget to display data.frame, using the JavaScript library ECharts3.

eSankey(dat, candleColor, size = NULL, title = NULL, subtitle = NULL,
  title.x = "center", title.y = "top", toolbox = TRUE,
  toolbox.orient = "horizontal", toolbox.x = "right",
  toolbox.y = "top", tooltip = TRUE, tooltip.trigger = "item",
  calculable = TRUE, opt = list(), ...)

`dat`	a data.frame object
`size`	an array of html widget width and height(either numeric pixels or percentage could be accepted): e.g. size = c(1024, 768).
`title`	an overall title for the plot. you can modify title widget after chart has been generated: sankeyEchart + eTitle(title = "your title.")
`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: `sankeyEchart + eTitle(title="main title", x = "left", y=10)`
`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. `sankeyEchart + eToolbox(show = TRUE)`
`toolbox.orient`	an element of c("horizontal", "vertical"), default is "horizontal" you can modify toolbox widget after chart has been generated: `sankeyEchart + 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: `sankeyEchart + eToolbox(x = "right", y="top")`
`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. `sankeyEchart + eTooltip(show = FALSE)`
`tooltip.trigger`	an element of c("axis", "item"), default is "item" for sankey chart. "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: `sankeyEchart + eTooltip(trigger = "item")`
`calculable`	logical whether the front-end interactive chart will support the drag-recalculable feature. the size and calculable option can be setted after bar chart has been generated through eOption: `sankeyEchart + eOption(calculable = TRUE)`

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