I think this is the expected behavior because the tooltip
triggeris set to beitemand there are no items if it's set to be'none'.5jvtdoz22#

I thought there were plans to snap to the nearest point for a graph with symbols set to "None"? I have some very large graphs which require trigger set to item, but drawing the symbols slows performance to the point that it stops responding.
Here's a jsfiddle . Performance will gradually slow down to a halt. Setting symbol to "none" drastically improves performance, but then trigger type item breaks. Trigger type axis shows way too many values to be very helpful.

I think it would be very beneficial to show item tooltips even the symbol is set to 'none'. Actually I find it a little counter-intuitive that the tooltip depends on the visibility of a symbol - the data item obviously is still there even if I do not want a special visualisation to be drawn. Currently, my workaround is to "hide" the item via itemStyle (transparent colors...), but that is not very convenient.
