我有一组1000*17的矩阵，每一行的1：16列是一个类的特征向量，17列是类别标记，怎样在二维的平面内画那个16维特征向量的散点图并且点的形状随17的不同而不同呢 谢谢啊！
给出矩阵前一部分数据【 88, 92, 2, 99, 16, 66, 94, 37, 70, 0, 0, 24, 42, 65,100,100, 8 80,100, 18, 98, 60, 66,100, 29, 42, 0, 0, 23, 42, 61, 56, 98, 8 0, 94, 9, 57, 20, 19, 7, 0, 20, 36, 70, 68,100,100, 18, 92, 8 95, 82, 71,100, 27, 77, 77, 73,100, 80, 93, 42, 56, 13, 0, 0, 9 68,100, 6, 88, 47, 75, 87, 82, 85, 56,100, 29, 75, 6, 0, 0, 9 70,100,100, 97, 70, 81, 45, 65, 30, 49, 20, 33, 0, 16, 0, 0, 1 40,100, 0, 81, 15, 58,100, 57, 47, 87, 50, 88, 40, 42, 36, 0, 4 3, 71, 0, 95, 45,100,100, 99, 79, 78, 48, 53, 31, 24, 54, 0, 7 79, 87, 98, 81, 71,100, 72, 73,100, 66, 91, 21, 48, 0, 0, 13, 9 92, 95, 30,100, 34, 68, 87, 89, 84, 78,100, 35, 64, 0, 0, 19, 9】就是这样的格式 主要我想体现多维数据在二维效果图上的可分性
