（When the static label formatter passes 2 different vertical labels, it displays the first label twice instead of displaying the two collection
labels。）

如果2个图形系列具有相同的系列标题，具有不同的系列颜色，则图例中仅显示第一个系列信息
When Y axis labels are huge values or strings, some part of vertical label is crossing vertical axis
When background color is set for graph using setBackgroundColor() method, little bit of color is crossing horizontal axis
setBorderColor and setBorderPaint methods of viewport class are not supported
