Hi mingeun.ahn,
Try to set the border color to "SameAsMainColor". The exact syntax depends on your programming language. It is Chart.SameAsMainColor for C#/Java/VB(NET), Chart::SameAsMainColor for C++, SameAsMainColor for Python/PHP and $perlchartdir::SameAsMainColor for Perl.
For example, for C++, it is:
layer->setBorderColor(Chart::SameAsMainColor);
for C#, it is
layer.setBorderColor(Chart.SameAsMainColor);
Best Regards
