我想在 Plotly 对象之上使用上下文菜单( jQuery contextMenu )。问题是,当我使用Box - 或Lasso -选择工具选择多个元素然后右键单击一个栏时,它会触发该栏上的单击事件,并且先前的选择会丢失。
如何防止在 Plotly 对象上发生右键单击,因此只需左键单击即可触发单击/选择事件,而右键单击仅用于打开上下文菜单?

time_stamp = seq.Date(as.Date("2018-04-01"), as.Date("2018-07-30"), 1),
val = runif(121, 100,1000),
col = "green", stringsAsFactors = F
)
