1	g2_action(plot_id, btn_id, ..., data = NULL, reorder = TRUE)

`plot_id`	Id of chart to interact with.
`btn_id`	Id of the `input_button()` that triggers the action.
`...`	Aspects, see `asp()`.
`data`	Data.frame containing data to plot.
`reorder`	Whether to internally reorder the data, namely the `x` and `color`. The `x` axis must be reordered in a descending order for most data type since G2.js plots data as-is. Moreover, `color` order of all data.frames passed either to this function or subsequent `fig_*` layers must be identical or the colors will might match the legends on the plot. However, one may sometimes not want the data to be reordered.
