ramarro123 commented on issue #9188: tooltip formatter when using axis trigger
URL: https://github.com/apache/incubator-echarts/issues/9188#issuecomment-428848085
 
 
   umm, i have created a demo here
   http://jsfiddle.net/Lb4nkfcj/
   
   i am using 4 series and a dataset with some "strange" mapping that will (eventually) allow me to create a gantt with a custom item renderer.
   
   Having said so, now the chart doesn't display anything :) that's expected...
   
   but, if i go around axe with cursor, i get "10" that's the size of dataset, not the size of series (that's 4)
   
   on params, for tooltip, i get the full dataset, so it's impossible to know at which point of axes i am.
   if i know the X position, then i can iterate the dataset to get the current position (or the nearest position, or whatever i want to do) but i haven't find a way to get the current X position.
   
   even if trigger is axis (expecially with trigger axis i will say) having the position/value of axis it's necessary, it allow to understand the current position of cursor.
