Line is a professional utility for deep analysis of analog stick performance quality. Unlike standard testers that only check circularity or polling rate, Line focuses on trajectory accuracy, signal stability, and real sensor resolution.

It is an indispensable tool for comparing Hall Effect sticks with standard potentiometers (ALPS), as well as for diagnosing "drift" and mechanism wear.

Key Features:

• Linearity Analysis: Calculates the deviation of the stick's movement from an ideal straight line. This helps you understand how predictable aiming will be in shooters.
• Tremor (Jitter) Detection: Measures the level of "noise" in the signal. High tremor levels can lead to micro-stuttering of the cursor, even on new gamepads.
• Resolution Check: Determines the real number of steps (bit-depth) the controller is capable of transmitting. The higher the value, the smoother the movement.
• Smart Filtering: The program records a series of movements and automatically selects the most representative (median) sample for the final graph, ignoring accidental hand errors.
• Cloud Statistics: Integration with Gamepadla.com allows you to upload your results to the database and compare your controller with thousands of others.

How to Use:

1. Run the program.
2. Stick Selection: Rotate the stick you want to test 3 times clockwise. The program will automatically detect it.
3. Testing Process:
   • Slowly move the stick from the center to the edge (in any direction).
   • Just as slowly return it back to the center.
   • Important: Try to move the stick at a constant speed. The optimal time for movement in one direction is 2-3 seconds.
4. Perform at least 3 full movements.
5. Press any button on the gamepad to finish the test.
6. Choose how to save the report (local JSON file or upload to the website).
