How can I draw dynamic line on the control about eventdrops HOT 1 CLOSED

        const drawCurrentTimeLine = (container, height, date) => {
            const timeline = d3.select(container)
                .selectAll('.timeline')
                .data([{ date }]);

            timeline.enter()
                .append('line')
                .attr({
                    class: 'timeline',
                    y1: 0,
                    y2: height,
                    x1: d => d.date,
                    x2: d => d.date,
                });

            timeline.attr({
                x1: d => d.date,
                x2: d => d.date,
            });
        };
