PX4 flight log plotter for ulog format

FlightPlot

Universal flight log plotter

Releases can be found on GitHub releases.

Overview

Supported formats:

• PX4 log (.px4log, .bin)
• APM log (.bin)
• ULog (.ulg)

Features:

• Data processing: low pass filtering, scaling, shifting, derivative, integral, etc.
• Track export in KML and GPS format
• Saving plot as image

Building from source

Requirements:

• Java 6 or newer (JDK, http://www.oracle.com/technetwork/java/javase/downloads/index.html)
• ant

Clone the repository. The --recursive flag is required to pull in the jMAVlib submodule).

git clone --recursive https://github.com/PX4/FlightPlot.git

Build:

cd FlightPlot
ant

If you want to create deb file for ubuntu, use gen_deb.

cd FlightPlot
ant gen_deb
sudo dpkg -i out/production/FlightPlot.deb

Run:

java -jar out/production/flightplot.jar

flightplot's Issues

Link to releases broken

The readme says that releases can be found in http://pixhawk.org/dev/flightplot but the page is just 404/not found.

Any link for windows download is broken

As title.

jMAVlib commit not available

git submodule update --init --recursive
fatal: reference is not a tree: 69f6e9908930fa3ec611e4cb2bae04aabf5a197a

FYI: @bkueng

Plot euler angles independently

At the moment you can only plot roll, pitch and yaw simultaneously when using the EulerFromQuaternion
operator. Would be nice to be able to plot them individually.

Match timestamps between plot and ulog messages

The messages contained in a log are displayed with the time since boot. The time axis of the plot is from log start time by default, but can be configured via the View menu.
Only if View->Boot time is selected is it possible to determine at what point on the plot's time axis the messages occur.

The messages' timestamps should change to match whatever time reference is used in the plot.

Encounter errors with java version's issue

I build FlightPlot at my macOS(10.5.2 Big Sur).It encounter errors like this:

% ant

Set up Travis to build this and re-link PX4 docs to it

@bkueng @AndreasAntener Could you look into setting up Travis for this and update the PX4 website to point to the resulting binaries? Flight plot is not very actively maintained and it starts to slow us down. We need to have control over the binaries we depend on.

Euler angles are not displayed

Hi, Thanks for FlightPlot.
Euler angles are not displayed in recent version.
Instead, quaternion is displayed but it is difficult to understand attitude change.
So in FlightPlot please make some attitude representation support function.

Environment:
By Pixhawk2.1, px4 v1.7.3 and FlightPlot v0.3.2

Processor of type "Expression" doesn't work for some fields/expressions

Description

I have a log file and I want to look at the magnetic field norm: sqrt(x²+y²+z²), where {x,y,z} are taken from parameters sensor_combined_0.magnetometer_ga[0,1,2].

Separately adding fileds sensor_combined_0.magnetometer_ga[i] works fine, but adding them as an expression does not: I can't see any plot:

Adding sensor_combined_0.magnetometer_ga[0] as "Simple":

Adding sensor_combined_0.magnetometer_ga[0] as "Expression":

How to reproduce

1. Download this log file
2. Open it in flightplot and add processor of type Simple with field sensor_combined_0.magnetometer_ga[0]. You should see a plot.
3. Add new processor of type 'Expression'. Enter sensor_combined_0.magnetometer_ga[0]/2 as an expression for the processor.

Expected behavior: you see 2 plots.
Actual behavior: you only see 1 plot.

Flightplot v0.3.2, ubuntu 16.04 LTS.

Display name of imported preset which is currently loaded

When you use "import preset", its name does not appear in the preset pulldown. One must manually type a name into the preset field and hit return to avoid having to import it again. This is very non-intuitive and also inconvenient.

Also, the menu names on this toolbar are truncated:

Two different EulerFromQuaternion sources not viewable at the same time

I opened a ulog, chose the set of variables
control_state_0.q[0] control_state_0.q[1] control_state_0.q[2] control_state_0.q[3]
with EulerFromQuaternion processor and did the same for
vehicle_attitude_setpoint_0.q_d[0] vehicle_attitude_setpoint_0.q_d[1] vehicle_attitude_setpoint_0.q_d[2] vehicle_attitude_setpoint_0.q_d[3].

The result is they newer get displayed at the same time. If both are enabled to view (with the checkboxes) I see either only the first set or the data of the first set in the colors of the second. If only one is displayed it works as expected.

Zoom issue (want to zoom only VTOL back tranzition)

I am using FlightPlot v.0.3.2 (flightplot.jar) and when I zoom the graph disapears
ulog example is on link

when I zoom only at back tranzition time

FlightPlot can't export to kml from ulg

only got this

Build fails with "java.lang.NoClassDefFoundError"

Hi, I'm trying to build FlightPlot from source but I'm getting a "NoClassDefFoundError".
I'm on macOS Big Sur (11.4).
I also needed to update the build.xml file; source and target versions (1.6) are now deprecated. I instead used "1.8".

Here's the complete error log:

I'm not familiar with the ant build tool -- how can I fix the problem and build the program?
Thanks!
