Nokia 5110 LCD, printing sensor values on screen, how?

So, I have a thumbstick connected to my breadboard and I want X&Y values to be printed on screen as I move the thumbstick.

I have checked the internet for sample codes but I ended up with LcdString("Hello World"); this code which doesn't accept analog signals from joystick. I mean, when I write LcdString(joyStickpin1); I'm getting errors.

You will need to write the glue code that converts the analogRead() values from the stick to something human-readable on the display.
