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

TabContents
ChannelsSelect channels, colours, scaling mode, and Y-axis assignment
EventsSelect events as vertical markers, or enable Show all events
DisplayToggle 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

ModeDescription
Scale to FitY-axis fits the min/max of the channel data in view
Scale to ReferenceUses the reference channel’s Y-axis range
Scale from DatabaseUses 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

OptionDescription
Show pathDraw lines between sequential points
Soft falloffSoft-edged points for dense clouds (easier to read when zoomed out). Adjust Radius when enabled
Reference shapeMarker style for the reference lap (disabled when soft falloff is on)
Show 1st / 2nd compareToggle visibility of comparison laps
1st / 2nd compare shapeMarker style for each comparison series
Show axis numbersX and Y axis labels
Min/max overrideManual 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.
