I has created a D3 Bar Chart project. Everything is working except the tooltip. I don’t know how the example page work but mine isn’t working. Every time the event is emitted, the error come out which say cannot read property 0 of undefined. I add the event listener as the example page does but the error is still there.
@lasjorg Ah… Sorry I deleted it.
I have added the title elements but the test said
I can mouse over an area and see a tooltip with a corresponding id=“tooltip” which displays more information about the area Tooltip should be hidden when mouse is not on an area: expected false to be true
