Drawing lines in canvas using accelerometer sensor data in windows phone 8.1

How to find pause in accelerometer values. Any logic ?

You asked those work which Motion class has done. The Motion class handles the low-level sensor calculation and allows applications to easily obtain the device’s attitude (yaw, pitch, and roll), rotational acceleration, and linear acceleration both due to gravity and user movement. If you cannot use this class in your app, maybe has no hardware in device, you shall use your favor search engine to find a logic to calculate the x,y,z provided by Accelerometer.
