How do I change the direction where the servo motors are going with a joystick?

Ive only just started learning arduino and Im trying to use one joystick with only the x axis to control two servo motors, but I need one of them to go clockwise and the other to go anticlockwise. Is there any way I can do this? Here is my code so far.

#include <Servo.h>

Servo servo1;
Servo servo2;
int joyX = 0;
int joyY = 1;

int joyVal;

void setup()
{
servo1.attach(1);
servo2.attach(2);
}

void loop()
{

joyVal = analogRead(joyX);
joyVal = map(joyVal, 0, 1023, 0, 180);
servo1.write(joyVal);

joyVal = analogRead(joyX);
joyVal = map(joyVal, 0, 1023, 0, 180);
servo2.write(joyVal);

delay(15);
}

Have you considered modifying one of the maps?

Please remember to use code tags when posting code

How would I modify the maps?

By reversing the order of two of the parameters?

For the second map try map( 0, 1023, 180, 0 )

Thank you very much, its worked now.
