PID Tuning Tab: Throttle Curve UI does not reflect actual throttle curve in FC #4589
Description
Describe the bug
The Throttle Curve displayed does not reflect the setting. When a mid point is set, it is shown as an offset along the X axis. A hover point is similar along the Y axis. With mid point set at 0.30 for example, this is the displayed graph:
The curve as desired is accurate within the flight controller, tested with throttle applied and throttle increases from above zero input.
To Reproduce
Merely set a mid point other zero or a hover point other than zero.
Expected behavior
Throttle curve in UI to reflect desired setting.

It appears to only be a UI issue as flight is as expected.
