问题 The following code (built from the answer of a related question) changes the line color in a Highcharts line chart when hovering the series without using the heavier series.update method, but the code line which should change also the datalabels text color is broken.

问题 I am following up on the solution in the below post: delete post from home page The solution worked. But the hidden post leave a trace on the home page, which I described in the comment section.
