I am new to Java and enrolled in a course to help me learn some basic Java to see if I am interested. I am interested in it and wish to pursue it. Anyways this is my first project so bare with me.

It is just a basic thermometer and conversion from Fahren. to Celsius.

If you look here you will find it:

I am stuck! As you can see the graph fills downward instead of up. How to I change this I have tried everything.
Here is the code in question:

Code:
private void drawThermometer(Graphics bar) {
		bar.setColor(Color.red);		

		bar.drawRect(40,40,43,220);		

		bar.fillRect(40,40 + 220,44,sliderValue * 2);

		bar.fillArc(40,235,44,50,360,-180);	

		bar.drawString("20", 22,220);								
		bar.drawLine(37,220,40,220);
		bar.drawString("40", 22,180);
		bar.drawLine(37,180,40,180);
		bar.drawString("60", 22, 140);
		bar.drawLine(37,140,40,140);
		bar.drawString("80", 22, 100);
		bar.drawLine(37,100,40,100);
		bar.drawString("100", 15, 60);
		bar.drawLine(37,60,40,60);
	}
Thanks!!
