title: Set bulletBorderColor to lineColor by default in amCharts
body: <p><a href="http://docs.amcharts.com/3/javascriptcharts/AmGraph#bulletBorderColor" rel="nofollow">According to the amCharts documentation, if bulletBorderColor isn't set, it will default to lineColor.</a> This doesn't seem to be working. I am building a theme for my team to use so they don't have to worry about setting colors every time they generate a chart. Does anyone have a workaround, or solution for this?</p>
