Hi, I've inherited a complex echarts implementation and am adding some new features.
I'm trying to find a way to sync multiple charts on a page. I've successfully synced the zoom by using the datazoom event and actions, but I'm struggling to set the x axis pointer across the charts. I've tried dispatching both the 'axisPointer' and 'updateAxisPointer' actions with no success. I had luck using a 'showTip' action, but we don't actually want the tooltips on and that doesn't work if they're off. I've also tried using setOptions with markArea, but that draws _behind_ the data no matter what z values I gave and I need to draw the axis on top, like the cursor. Does anyone have any suggestions? Thanks for your help, James
