updatePlot
Description
updatePlot(
adds or updates the plot with name mapper
,plotName
,plotFunc
,requiredSignals
)plotName
stored in
mapper
. Specify the plot function as a predefined plot name or
function handle and the required signals for the plot. For a list of preconfigured signals
and plots, see Predefined Signals and Predefined Plots.
Input Arguments
mapper
— Flight log signal mapping
flightLogSignalMapping
object
Flight log signal mapping object, specified as a flightLogSignalMapping
object.
plotName
— Name of plot
string scalar | character vector
Name of plot, specified as a string scalar or character vector. This name is either
added or updated in the AvailablePlots
property of
mapper
.
Example: "IMU"
Data Types: char
| string
plotFunc
— Function for generating plot
function handle
Function for generating plot, specified as a function handle. The function is of the form:
f = plotFunc(signal1, signal2, ...)
"Names"
and
"Values"
, and generates a plot output as a figure handle using
those signals.
Example: @(acc, gyro, mag)plotIMU(acc, gyro, mag)
Data Types: function_handle
requiredSignals
— List of required signal names
string array | cell array of character vectors
List of required signal names, specified as a string array or cell array of character vectors.
Example: ["LocalNED.X" "LocalNED.Y" "LocalNED.Z"]
Data Types: char
| string
More About
Predefined Signals
A set of predefined signals and plots are configured in the flightLogSignalMapping
object. Depending on your log file type, you can map
specific signals to the provided signal names using mapSignal
. You
can also call info
to view the
table for your log type and see whether you have already mapped a signal to that plot
type.
Specify the SignalName
as the input to mapSignal
. Signals with the format SignalName#
support mapping multiple signals of the same type. Replace #
with incremental integers for each signal name when calling mapSignal
.
The predefined signals have specific names and required fields when mapping the signal.
Predefined Signals
Signal Name | Description | Fields | Units |
---|---|---|---|
Accel# | Raw accelerometer reading from IMU sensor | [ax ay az] | m/s2 |
Airspeed# | Airspeed reading of pressure differential, indicated air speed, and temperature | [PressDiff, AirSpeed, Temp] | Pa, m/s, ℃ |
AttitudeEuler | Attitude of UAV in Euler (ZYX) form | [Roll, Pitch, Yaw] | radians |
AttitudeRate | Angular velocity along each body axis | [xRotRate, yRotRate, zRotRate] | rad/s |
AttitudeTargetEuler | Target attitude of UAV in Euler (ZYX) form | [TargetRoll, TargetPitch, TargetYaw] | radians |
Barometer# | Barometer readings for absolute pressure, relative pressure, and temperature | [PressAbs, PressAltitude, Temp] | Pa, m, ℃ |
Battery | Voltage readings for battery and remaining battery capacity (%) | [Volt1,Volt2, ... Volt16, RemainingCapacity | V, % |
GPS# | GPS readings for latitude, longitude, altitude, ground speed, course angle, and number of satellites visible | [lat, long, alt, groundspeed, courseAngle, satellites] | degree, degree, m, m/s, degree, n/a |
Gyro# | Raw body angular velocity readings from IMU sensor | [GyroX, GyroY, GyroZ] | rad/s |
LocalNED | Local NED coordinates estimated by the UAV | [xNED, yNED, zNED] | meters |
LocalNEDTarget | Target location in local NED coordinates | [xTarget, yTarget, zTarget] | meters |
LocalNEDVel | Local NED velocity estimated by the UAV | [vx vy vz] | m/s |
LocalNEDVelTarget | Target velocity in local NED coordinates | [vxTarget, vyTarget, vzTarget] | m/s |
Mag# | Raw magnetometer reading from IMU sensor | [x y z] | Gs |
Predefined Plots
After mapping signals to the list of predefined signals using mapSignal
,
specific plots are made available when calling show
. To view a
list of available plots and their associated signals for your specific object, call
info(mapper,"Plot")
. If you want to define custom plots based on
signals, use updatePlot
.
Each predefined plot has a set of required signals that must be mapped.
Predefined Plots
Plot | Description | Signals |
---|---|---|
| Stacked plot of roll, pitch, yaw angles and body rotation rates | AttitudeEuler, AttitudeRate, Gyro# |
| Estimated attitude of UAV and the attitude target set point | AttitudeEuler, AttitudeTargetEuler |
| Battery consumption plot | Battery |
