[Solved]-How to change the series color and mark after I draw the line chart in highcharts?Does it has databound event?-Highcharts

yes, this is available in the series.update() method. you would do something like:

chart.series[0].update({
    color: color ? null : highcharts.getoptions().colors[1]
});

where series[0] is the index of the series you want to update.
