+# Waveform Widget Plotting Ruleset
+
+The Waveform widget allows plotting data from scans generated within the BEC framework. Each scan produces a **scan item
+**, which includes measurement data from various devices, as well as additional metadata (e.g., devices driving the
+scan, such as `motor_x`, `motor_y`, etc.).
+
+The rules described below define how data from different devices and scans can be plotted together, depending on the
+selected `x_mode`.
+
+---
+
+## Types of Curves
+
+- **Live Curves**
+    - Continuously updated from the currently running scan.
+    - Dynamically adapt based on live data.
+
+- **History Curves**
+    - Static curves representing data from a specific completed scan (e.g., scan 110).
+    - Displayed only if compatible with the currently selected x-axis device.
+
+---
+
+## General Compatibility Rules
+
+- Data from devices within **the same scan item** can always be plotted against each other, provided they have the same
+  number of data points.
+    - Example: plotting `detector_1` against `detector_2` from scan 110 to check signal correlation is valid.
+
+- Data from **different scan items** cannot be plotted against each other.
+    - Example: plotting x-data from `motor_x` in scan 110 against y-data from `detector_1` in scan 111 is not allowed.
+
+---
+
+## Specific Rules for Each `x_mode`
+
+### 1. `x_mode='auto'` (default)
+
+- Automatically determines the device for x-axis scaling from the currently running (live) scan.
+- The primary device used for scaling is the first device listed in the current scan's `scan_report_devices` (usually a
+  positioner in the case of step scans).
+- **Live Curves**:
+    - Always plotted against the selected x-axis device from the current scan.
+- **History Curves**:
+    - Each history curve is linked to a specific scan item with scan ID.
+    - Waveform widget checks compatibility with the currently selected x-axis device from the live scan.
+    - If the selected x-axis device data exists in the history curve’s original scan item, the curve is displayed.
+    - If the selected x-axis device data does not exist in the original scan item, the history curve remains **hidden**
+      until a compatible device is selected again.
+
+_Example Scenario_:
+
+- The live scan currently uses `motor_x` as the x-axis device. Any history curve will only be displayed if its original
+  scan item contains data for `motor_x`. If not, the history curve is hidden.
+
+---
+
+### 2. `x_mode='timestamp'`
+
+- X-axis scaling is based on timestamps from each data point.
+- All curves, both live and history, are always compatible, as timestamps provide a universal and absolute reference for
+  the x-axis.
+- Curves from different scan items can appear simultaneously, regardless of the devices measured.
+
+---
+
+### 3. `x_mode='index'`
+
+- X-axis scaling uses data point indices (0, 1, 2, ..., N-1).
+- Allows plotting multiple curves of varying lengths in the same view.
+- All curves are always compatible, as indices represent relative positions, independent of device or timestamp, it is
+  up to the user to interpret the x-axis.
+
+---
+
+### 4. `x_mode='device'`
+
+- User explicitly selects a device to scale the x-axis.
+- The chosen device must exist in each curve’s respective scan item.
+- **Live Curves**:
+    - Continuously displayed if the selected device data is being measured in the current scan.
+- **History Curves**:
+    - Displayed only if the selected device exists in the scan item from which the history curve originates.
+    - Remain **hidden** if the selected device is not present in the original scan item, reappearing only when a
+      compatible device is chosen again.
+
+---
+
+## Key Technical Points
+
+- Each curve stores its own independent x and y data sets (as it is defined by `pg.PlotDataItem`, allowing simultaneous
+  plotting of multiple curves with different data lengths.
+- Compatibility checks ensure that plotting meaningful comparisons is always possible, avoiding combinations of
+  unrelated or non-compatible datasets.
