[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.
