Hello everyone, I’m new in this field, but I’m trying to work in this project, in which I have to read values (x,y,z) using the accelerometer Altimu-10 v4 ang get these values on my screen using arduino MEGA 2560.
Thanks you for helping 
School project?
Link to accelerometer?
Analog outputs?

The Altimu-10 v4 seems to have an I2C interface.
We plan to have Pololu’s Altimu-10 v4 listed soon, and they offer Arduino libraries for each sensor:
github.com/pololu/l3g-arduino
github.com/pololu/lsm303-arduino
github.com/pololu/lps-arduino
This Arduino program (sketch) allows an Arduino connected to a MinIMU-9 v3 or AltIMU-10 v3 (or older versions of those boards) to function as an attitude and heading reference system, calculating estimated roll, pitch, and yaw angles from sensor readings that can be visualized with a 3D test program on a PC.

Attached you will find the schematic for the Pololu Altimu-10 V4 which may also help.
