C++ Line graph acting funky - c++

Question

I am trying to create a line graph that displays temperatures that have been read from a local file. Currently, everything is working as intended except the graphical output.
Right now, my else statement for the negative numbers is not working correctly. In addition, some numbers appear to be shown and some do not.
Lastly, the numbers that are displaying are not showing the right number of '*". I know I am close but cannot crack the code...
#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>
using namespace std
int main()
{
//Variable declarations
int numberOfStars;
int printStars;
int temp;
int count = 0;
string lineBreak = " | ";
ifstream tempData;
tempData.open("tempData.txt");
cout << "Temperatures for 24 hours: " << endl;
cout << " -30 0 30 60 90 120" << endl;
printStars = 0;
while (count < 24) {
tempData >> temp;
if (temp >= 0) {
numberOfStars = temp / 3;
cout << setw(4) << temp << setw(10) << lineBreak;
while (printStars < numberOfStars){
cout << '*';
printStars++;
}
cout << endl << endl;
}
else {
numberOfStars = temp / 3;
while (numberOfStars > printStars) {
cout << '*';
printStars++;
}
cout << setw(4) << temp << setw(10)<< lineBreak << endl << endl;
}
count++;
}
//Closing program statements
system("pause");
return 0;
Currently it is outputting:
Thanks for help in advance.

Oh just put your printStars = 0; in the while :)
And do numberOfStars = temp / 3 + 1; if you want to have one star for temp < 3.
EDIT: You can simplify a lot your code. You can create a string with n time a character very easily. Your code should look like this:
#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>
using namespace std;
int main()
{
//Variable declarations
int numberOfStars;
int numberOfSpaces;
int temp;
int count = 0;
string lineBreak = " | ";
ifstream tempData;
tempData.open("data.txt");
cout << "Temperatures for 24 hours: " << endl;
cout << " -30 0 30 60 90 120" << endl;
while (count < 24) {
tempData >> temp;
numberOfStars = temp / 3 + 1;
if (temp >= 0) {
cout << setw(4) << temp << setw(10) << lineBreak;
cout << string(numberOfStars, '*');
}
else {
cout << setw(4) << temp;
numberOfSpaces = 7 + numberOfStars;
// Prevent any ugly shift
if (numberOfSpaces < 0)
{
numberOfSpaces = 0;
numberOfStars = -7;
}
cout << string(7 + numberOfStars, ' ');
cout << string(-numberOfStars, '*');
cout << lineBreak;
}
cout << endl << endl;
count++;
}
//Closing program statements
cin.get();
return 0;
}
