Plot Types
EmVision supports six plot types. Select the type in Layout Editor mode, from the plot’s context menu, or when creating a new plot pane.
Opening plot setup
For line and scatter plots:
- Click the pencil (configure) control on the plot, or
- Right-click the plot and choose Settings at the top of the menu (same dialog as the pencil).
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 channels from the Measurements panel (right-hand drawer) onto the plot to add them quickly
Tip
Drag any channel from the right-hand Measurements list onto a line plot to plot it. No need to open the channel setup dialog first.
Configuration tabs
| Tab | Contents |
|---|---|
| Channels | Select channels, colours, scaling mode, and Y-axis assignment |
| Events | Select events as vertical markers, or enable Show all events |
| Display | Toggle axes, race milestones, corners/straights |
Show all events
On the Events tab, Show all events draws every event in the log without picking them one by one. When it is on, the individual event list is disabled. Uncheck it to choose a specific subset of events.
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 (Show path)
- Marker type selection for the reference series
- Colour range boxes for Z-channel segmentation
- Double-click a range box to toggle visibility; drag to apply the same toggle across ranges
- Overlay comparison laps with fixed overlay colours (reference keeps Z/channel colouring and paints on top)
Scatter setup options
| Option | Description |
|---|---|
| Show path | Draw lines between sequential points |
| Soft falloff | Soft-edged points for dense clouds (easier to read when zoomed out). Adjust Radius when enabled |
| Reference shape | Marker style for the reference lap (disabled when soft falloff is on) |
| Show 1st / 2nd compare | Toggle visibility of comparison laps |
| 1st / 2nd compare shape | Marker style for each comparison series |
| Show axis numbers | X and Y axis labels |
| Min/max override | Manual axis limits for X and/or Y |
Open setup with the pencil icon or right-click → Settings.
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. Import tracks via File → Import Track File (see Opening Logs). Creating GeoJSON maps is covered under Creating a Track Map.
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.
