2D and 3D relationship plots

Plot one channel against another, or three channels in 3D, straight from existing channels, with no formula or lookup table.

Where to find it

Steps

Add the plot
Add a Relationship plot and choose 2D (the default) or 3D under Plot dimensions.
Pick the channels
Set X channel and Y channel, plus Z channel in 3D, from recorded or saved calculated channels, for example X = RPM, Y = TPS and Z = Lambda. The points appear as soon as the axes are set; in 3D, Z also drives the Color scale.
Set scope and filters
Open Scope and filters to pick the entire recording, the current selection, a lap or Compare laps, plus a Region and a saved Condition. Laps are told apart by color.
Move around
2D: drag to pan and scroll to zoom. 3D: drag to rotate, Shift-drag to pan and scroll to zoom, or use Top view · XY, Front view · XZ and Side view · YZ. Show grid and Reset view are in the plot tools.
Read values
Click a point, or use ←/→ on the focused plot, to read its values. Locate in telemetry moves the cursor to that moment.

Fits in 2D
Fit offers Off, Linear, Quadratic and Cubic, with R² and RMSE in the statistics details.
Binned statistics
X bins (Off, 8, 16, 32 or 64) adds a table of statistics per bin, with Export CSV.
How points are paired
Samples are aligned on the X channel's clock; a point with any missing value is left out.
No lookup table needed
To see RPM, TPS and Lambda together, use a 3D relationship plot. Lookup tables are for creating a new channel from a known relationship.
Lattiro Assistant · Beta (invite only)
In the beta, the assistant can add a relationship plot, switch it between 2D and 3D and set the X, Y and Z channels; you can keep editing it by hand.
