This seems very odd to me so thought I’d bring it up here. I have points on a map (in a notebook) I want to change the colour when they are clicked.
This works
d3.selectAll('circle')
.on('click', function(d, i) {
d3.select(this)
.style('fill', 'orange');
});
but this shorter form doesn’t’
.on("click", d => {
d3.select(this)
.style('fill', 'orange');
});
What the heck? Any ideas what the reason is?
