The line graph stylesheet included a fair amount of calculation, and the stylesheet rendering lines of text also included a fair amount of logic to calculate the y coordinate.
线图样式表包括了大量计算，并且呈现文本行的样式表还包括了大量逻辑来计算y坐标。
True multitouch capability would allow for an X and Y coordinate reading of each finger position.
真正的多触点功能将允许读取每个手指位置的X和Y坐标。
For example: (x, y) coordinate pairs, employee records from a database, etc.
例如(x,y)坐标点，数据库中的员工记录等等。
But the quadratic curve can be used only in condition when each X-coordinate of the points sequence mapping to only one Y-coordinate, so it can't be used in fitting closing curve.
但二次多项式只能拟合x坐标与Y坐标之间成函数关系的点序列，无法拟合闭合曲线。
