3 axis data confusion

Hi, I recently just got my 3 axis accelerometer, the MMA7361 from Sparkfun; datasheet(http://www.sparkfun.com/datasheets/Components/General/MMA7361L.pdf) and I soldered all the connecters to pins (i forgot what it’s called). Anyway, I wrote a code to see if the accelerometer works. But my problem is that I keep getting numbers that don’t change much even if I give it a sudden acceleration. Feel free to alter the code and please give me some advice on how to make this better. I also added a snippet of my results. Thanks

int x_axis = 0;
int y_axis = 1;
int z_axis = 2;
int x_result;
int y_result;
int z_result;
int sleep = 2;
int g_select = 4;

void setup ()
{
  Serial.begin(9600);
  digitalWrite(sleep, HIGH);
  digitalWrite(g_select, HIGH); 
}

void loop ()

{
  int x_result = analogRead(x_axis);
  int y_result = analogRead(y_axis);
  int z_result = analogRead(z_axis);
  Serial.print(x_result);
  Serial.print(" ");
  Serial.print(y_result);
  Serial.print(" ");
  Serial.print(z_axis);
  Serial.println();
  delay(500);
}

Results: (flat on table)

The numbers won't change much if you only print them out twice a second.

What happens if you align the different axes with Z (downwards)? Do the results agree with each other?

int z_axis = 2;
Serial.print(z_axis);

Hmmmm.

Thanks for the reply! I changed the sampling rate to 100 milliseconds and my results show more changes when i move it so thats fixed but the Z axis is still two. I tried switching cables (x cable goes in to z) but the results are still the same.

Yes, Z will always be two.

Before you write a pin HIGH, best make sure it is an output first.

Ok thanks. Anyway, when I replied your first comment, sorry if I was telling you something completely different cause my computer didn't load the quotes and I thought you meant something else. Anyway, I fixed the issue and the Z axis is sending out signals properly. Thank you so much!
