加@@

The histogram is what you want?

我想把柱形图对应的频数导入数据集，不想手工输入。

data a;
  input x1 x2 x3@@;
cards;
80 12 120 60 5 156 56 6 250 56 15 350
58 23 360 77 35 450 40 25 359 65 18 368
56 6 250 56 15 350 58 23 360 77 35 450
40 25 359 45 16 389 66 18 400
;
run;


Is this what you need?
proc freq noprint;
  tables x1 /nopercent out=x1;
  tables x2 /nopercent out=x2;
  tables x3 /nopercent out=x3;
run;

proc print data=x1;run;
proc print data=x2;run;
proc print data=x3;run;

不是简单的数个数，如X3希望能把359-368的个数加起来，即先分组再计数。

suggestion to lz:
1.gchart can't do this automatically.
2. design your our  groups(intervals by my understanding) and count the frequency of numbers  which locate in your interval
3. write the # of frequency of groups into a file

楼上的说的是什么软件里面的操作？
