phase_off_separate.jpg
The user wants a detailed description of an image containing three line graphs stacked vertically.
I need to describe:
1.  **Overall Layout:** Three distinct plots arranged one above the other. They share an x-axis but have separate y-axes (though labeled similarly). There is a legend on the right.
2.  **Axes and Labels:**
    *   Y-axis label for all three: "Amplitude (Arbitrary)". The scale goes from -2 to 2 with tick marks at integers (-2, -1, 0, 1, 2).
    *   X-axis label for the bottom plot: "Time (Arbitrary)". The scale has major ticks at 0.0, 2.5, 5.0, 7.5.
3.  **The Plots (Top to Bottom):**
    *   **Top Plot:** Labeled "base" on the right side. It shows a red sinusoidal wave. It starts near -0.5 at x=0, goes up to a peak of 1 around x=2.5, down to a trough of -1 around x=5.0, back up to a peak of 1 around x=7.5, and ends near -0.5. Wait, let me look closer.
        *   At x=0, y is roughly -0.5.
        *   Peak at x approx 2.5, y = 1.
        *   Trough at x approx 5.0, y = -1.
        *   Peak at x approx 7.5, y = 1.
    *   **Middle Plot:** Labeled "phase_off" on the right side. It shows a green sinusoidal wave.
        *   At x=0, y is roughly -1 (it starts at the trough).
        *   Peak at x approx 2.5, y = 1.
        *   Trough at x approx 5.0, y = -1.
        *   Peak at x approx 7.5, y = 1.
    *   **Bottom Plot:** Labeled "sum" on the right side. It shows a blue sinusoidal wave.
        *   At x=0, y is roughly -1.5.
        *   Peak at x approx 2.5, y is roughly 1.6 or 1.7 (higher than the others). Let's look at the grid lines. The peak is between 1 and 2, closer to 1.5. Actually, looking at the math of wave addition: if base is sin(x) + offset and phase_off is cos(x), sum would be... wait, let's just describe what I see visually.
        *   Visual check for bottom plot: Starts around -1.4 or -1.5. Rises to a peak around x=2.0 (slightly before 2.5). The peak height is roughly 1.6. Then goes down to a trough at x=5.0, y approx -1.6. Then up again.
        *   Wait, let me re-evaluate the peaks.
            *   Top (Red): Peak at ~2.5, value 1. Trough at ~5.0, value -1.
            *   Middle (Green): Starts at trough (-1) at x=0. Peak at ~2.5, value 1. Trough at ~5.0, value -1. This looks like a cosine wave shifted or just a sine wave starting at the bottom.
            *   Bottom (Blue): Starts around -1.4. Rises to peak around x=2.0? No, looking closely at the grid lines... The peak is slightly before 2.5. Let's say x=2.2. The height is roughly 1.6. Then trough at x=5.8 approx? No, let's look at the symmetry.
            *   Actually, let's just describe the visual shape without over-interpreting the math unless it's obvious.
            *   Blue wave: Starts low (around -1.4). Rises to a peak around 1.6 near x=2.5? No, the peak is clearly shifted left compared to the red one. The red peak is at 2.5. The blue peak is slightly before 2.5. Wait, looking really closely at the bottom graph...
            *   Let's look at the grid lines again. Vertical lines are at 0.0, 2.5, 5.0, 7.5.
            *   Red wave: Peak aligns perfectly with vertical line 2.5. Trough aligns with 5.0.
            *   Green wave: Starts at trough (-1) at x=0. Peak aligns with 2.5.
