Plot Types
EmVision supports six plot types. Select the type in Layout Editor mode, or when creating a new plot pane.
Line Plot
The primary analysis plot. Displays one or more channels against time or distance on the X-axis.
Features
- Multiple channels with independent Y-axis scaling
- Event markers along the X-axis
- Lap and sector milestone bands (when enabled)
- Corner and straight segment highlighting
- Channel highlight and hide toggles
- Drag-and-drop channels from the measurements panel
Configuration
Click the configure (pencil) icon on a line plot to open the setup dialog:
| Tab | Contents |
|---|---|
| Channels | Select channels, colours, scaling mode, and Y-axis assignment |
| Events | Select events to display as vertical markers |
| Display | Toggle axes, race milestones, corners/straights |
Scaling Modes
| Mode | Description |
|---|---|
| Scale to Fit | Y-axis fits the min/max of the channel data in view |
| Scale to Reference | Uses the reference channel’s Y-axis range |
| Scale from Database | Uses predefined min/max from the channel database |
Scatter Plot
Plots one channel against another (X vs Y), with an optional third channel controlling point colour.
Features
- X, Y, and optional Z (colour) channel assignment
- Connecting lines between sequential points
- Marker type selection
- Colour range boxes for Z-channel segmentation
- Double-click a range box to toggle visibility; drag to apply the same toggle across ranges
Track Map
GPS position plot showing the vehicle path around a circuit.
Features
- Vehicle position marker with configurable dimensions
- Track outline from imported GeoJSON or log GPS data
- Cursor follows vehicle position
- F10 toggles between track-following and car-following zoom modes
Vehicle dimensions are set in Settings.
Lap Timing
Split time table showing sector and lap times in a grid format.
Features
- Sector times per lap in columns
- Best sector and best lap highlighting
- Special lap columns (in-lap, out-lap)
- Totals row
This plot reads directly from the log’s lap timing data — no additional configuration is required.
Gauge Area
Dashboard-style gauge display showing channel values at the cursor position.
Features
- Multiple gauge styles in a single pane
- Values update as the cursor moves through the log
- Useful for replicating a dash layout view during playback
Lap Matrix
Colour-coded matrix comparing channel statistics across laps.
Features
- Configure which channels appear as rows
- Colour bands highlight value ranges
- Drag rows to reorder
- Quickly identify which lap had the highest/lowest value for each channel
Open the Lap Matrix settings from the toolbar button within the plot to add channels and configure colour bands.
