I have a program that requests a series of numbers from the user. Once everything is inputted the frequency of each number within a range is supposed to be graphed in a JFrame. The graph basically would show on the y-axis the ranges, ie 10-19, 0-9, and the x-axis would show the number falling into each range using a rectangle coming out of the location of the range on the y-axis. I can get the input to work and I have verified that my code compiling all of the data into an array that adds up the frequency is working. My problem is I have no clue where to start with the graphing part of it. I have tried some things with Swing and AWT but with my newbie understanding of Java the results were not good. Here is the code I already have:

Code:

import java.io.*;
import javax.swing.*;

public class Histogram {
    
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        
        // creates
        int inputtedValue[] = new int[ 10 ];  // array to hold inputted data
        
        for( int inputCounter = 0; inputCounter < inputtedValue.length; inputCounter++ ) {
            String input = JOptionPane.showInputDialog
                    ("Please enter a number between 0 and 99\n" +
                    "Stop entering values at any time by entering -1.\n");
            
            int numberProvided = Integer.parseInt(input);
            inputtedValue[ inputCounter ] = numberProvided;
               
        HistogramFreq freqCalc = new HistogramFreq(inputtedValue);
        freqCalc.determineFrequency();
        }
    } // end main
} // end class Histogram

Code:

import java.awt.*;
import javax.swing.*;

public class HistogramFreq
{
    private int valuesProvided[];
        
     public HistogramFreq(int inputtedValue[])
    {
        valuesProvided = inputtedValue;
    }
    
    public void determineFrequency(){
        // stores frequency of inputted numbers in the appropriate ranges
        int frequency[] = new int [10];
        
                // for each range increment the appropriate range 
               for( int valueEntered : valuesProvided)
                    ++frequency[valueEntered/10];
         }  // end method determineFrequency()
     } // end class HistogramFreq

Thanks
