HighCharts - Dynamically Change Axis Title Color

问题:

I need to change the font color of the axis title after it has been created. I have tried all variations on the commands below but can't get anything to work.

Chart.yAxis[0].setOptions({ yAxis: { title: { styles: {  color: '#FFFFFF' } } } });
Chart.yAxis[0].axisTitle.attr({ styles:{ color:"#FFFFFF" } });

Again, I can do this upon creation of the plot, I just need to find the option command or style command to update this dynamically.

Thanks

You can use update() function.

chart.yAxis[0].update({
                title:{
                    style:{
                        color:'red'
                    }
                }
            });
