i'm stuck with assignment... i am trying to do easy histogram with x-axis info(like number options) and y-axis info(like # of occurrence) all within a figure by C++. however, i've no ideas to proceed at all. i am thinking about the following data: x-axis values are 1,2, and 3. y-axis values are 3, 7, and 4 for each x value respectively. i hope to hear you guys. great thx.
if the above is too easy, please help me out w/ the folowing: Code: #include<iostream> using namespace std; int main() { int i; int j; int k; int occurrence[10]={0,0,0,0,0,0,0,0,0,0}; int data[10]={6,14,82,42,46,32,97,44,27,68}; for (j=0; j<10; j++) { for (i=0; i<10; i++) { if ((data[j] >= 10*i) && (data[j] < 10*i+9)) occurrence[i]++; } } cout << "occurrence # is "; for (k=0; k<10; k++) cout << occurrence[k]<<" "; } ---------------------------------------------------------- i don't know how to plot. i can't find the funtions. x-axis is 0-9,10-19,..,90-99. y-axis is the result above. also, how can i generate zero array at once for occurrence w/o typing them out ? great thx !
For plotting you need to be doing some graphics fucntions and can you tell what OS and compiler you are using.
