Question

I m writing a function to plot a histogram but I m stuck with a problem. This is the code

void plotHist(int num, regression *r, histData *h)
{
   int i, j;
   for (i = 0; i< h->numHist; i++)
   {
       printf("%2f	|", h->hist[i].xValue) ;
           for ( j = 0 ; j < h->hist[i].yFrequency/5; j ++)
           {
               printf("*");

           }


        printf("
");
    }

}

我接受筛选的结果是:

                -199.422 |  
                -142.232 |****
                -98.232  |******
                -21.32   |***********
                 43.424  |****************
                 58.234  |***************
                 92.123  |*********
                 189.5   |****

The problem is that I have to add another array to this histogram by "o" letters which I don t know how to do. The result should be like this:

        -199.422 |  o
        -142.232 |****o
        -98.232  |******o
        -21.32   |********o**
        43.424   |**********o*****
        58.234   |********o******
        92.123   |******o**
        189.5    |****o

不要立即用印本印刷。相反,数字显示,所有数据点都将在你进行印刷之前。这样一来,你就不得不检查你每台数据时间,而第二阵列必须位于他的画面区域内。
