Getting the chart to work in my Java program

I need to get my chart to work in the Java program I have developed. I have gotten the basic layout to work, but have not gotten the information from the calculations to work to make the graph. Let me know what I'm doing wrong. MortgageCalculator.java Chart.java InterestRate-Term.txt

It is not printing because yiou use number of months instaed of number of yaerss
and when it comapres number of montsh with 10 in your chart
it odes not go
to that picve which should darw your red line

This code is from your caclulator part

    public void onButtonChart()
            {
                new Chart((int)(number_of_months));
                System.out.println(""+number_of_months);

        }

Open in new window

This code is from Chart:

public Chart( int number_years)
   {
            //set title for the window
            super( "Mortgage Payment Calculator Chart" );

            this.number_years = number_years ;


	  // set the size of the window and let it be visible
	  setSize( 740, 490 );
	  setVisible( true );

   }

So you pass number of months and read it as number of years.

Thanks. Looks like it working.

Yes, it does.
In general it is definitely not a good practice to
use actual numbers in the paint(g) method.
You should first retrieve the size of yoour panel
and then exprsess everithyng as height and width mmultuiplied by the
ratio which you need for each point, line, etc
which you are drawing.
Otherwise, when you resize your window, your
drawing will be screwed up.
Well, for the first try - it is OK.
But in general, this is good to keep in mind.
