弱弱地认为是这样的:
在panel workfile中选中你要作图的变量,open as group,然后view/graph/在graph type那里选择scatter类型,另外在panel options那里有五个选项,其中:
1、stack cross sections是把所有数据堆在一张图上,simply stacks the data for each cross- section and plots the data without regard for panel structure。
2、individual cross sections是每个个体一张图,display a graph of the data for each cross-section in its own frame。
3、Combined cross sections,displays separate lines for each cross-section
in a single graph.
4、means of cross sections,根据dateid求平均值,并将各截面叠加在一张图上,如果数据较多的话这种图看起来清楚些
5、median of cross sections
