Building xy graphs

Question

I'm trying to build xy graphs with multiple plots in a loop. In the attach, if I cluster each element and build an array , the plot looks fine (XY Graph). If I try to do it in a loop, I get extra points added (XY Graph 2). All the xy sets dont have the same number of elements, and the loop version pads with 0s to make the inner arrays square. This doesn't happen when I do it manually. How can I make this work in a loop?
TIA,
Bill F

HI:
         我想在XYgraph 中同时显示多条曲线，具体情况如下：（参考附件）
          当外循环循环一次时，内循环执行完得到一条独立曲线
          当................第二次时，....................又得到.....​...................
          依次得到许多独立的曲线，同时显示在XYgraph中，同一坐标下。
          在附件中得到的曲线其实是一条曲线，都是首尾相接，因为它是在整个循环执行完后得到的。我用很多办法试，总得不到​独立的曲线簇，第一条的首和第二条的尾相连，依次类推，其实还是一条曲线。我用的LABV7.0, 请高手指导。
