Don't plot in yellow
Personnaly, I think it's really hard to see the yellow lines on white. Any easy way you could get rid of yellow? Or make it darker?
MAVLink logs support
I've added codegen-free mavlink library to jMAVlib and now it should be easy to add mavlink logs support. Message definitions XML file can be selected in runtime, so in Open dialog we should be able to choose "APM / PX4 / Custom XML". Maybe it will be time for custom Open dialog.
CLI to save plot as image
It would be extremely cool if one could use the CLI to plot an image using a FlightPlot preset. :) @DrTon I think you already had something like this in mind?
For instance
flightplot plot -r 1024x1024 log1.bin preset.fplot out.png
Add feature to visualize flight.
Hi Anton
I think it would be a great idea to add a feature to FlightPlot which allows to visualize the attitude/position of the vehicle. I have done a python script which allows me to do that https://github.com/tumbili/FlightAnalyzer but it would be great if this is possible with FlightPlot.
I think for heavy maneuvers euler angles are not good to be analyzed anymore and quaternions are not very intuitive either. Would you be interested in helping to add this feature? I will have some spare time soon and am willing to invest it.
use flightplot to tune controller
I found a guide about how to use flight to tune controller,the website is http://www.pixhawk.org/dev/flightplot_pos_control
but I have some questions as following
1、what it says hold altitude means switch to ALTCTL mode?
2、how to use flightplot to tune position controller and attitude controller?
Build broken on OSX 10.10.5
The build seems to be broken on Mac using JDK 8u73. Following the instructions on README.md, I first ran into a build error due to a missing jMAVlib/src directory. I attempted to fix that, but then the build fails due to a complaint about missing packages. I'm unfamiliar with the java build process, so cannot troubleshoot further than this. I have included the console output below:

Use jMAVlib and la4j gracefully
Now jMAVlib included as submodule but is has submodule la4j inside, it may be confusing and ugly. How to do this better? At least jMAVlib will be updated from time to time and I want to get the change in FlightPlot easyly. @AndreasAntener, any ideas?
add option to plot markers on datapoints
This would aid in recognizing dropouts in the log.
GPS.Altitude View Problem
Hi first thanks for the great app. I have this rather inconvenient problem with the view. Here our home spot is at 600-650 meters altitude we fly at 600-900 meters height so When I turn on the GPS.Alt in the view the number is so high that all the other graphics get almost like a line around the 0 point. It is especially inconvenient when we have to analyze VTOL transitions. So please can you add a way that FlightPlot detects where the 0 ground is and provide in some way Relative Altitude Visualization instead of the GPS.Alt in real numbers.
File/Exit menu option is missing
I would expect an option to close the program in the File menu.
Open mavlink files or serial ports for realtime plotting.
It's possible to open and update periodically files with mavlink logs, or even open serial device and implement realtime plotting. This will require custom "Open file/device" dialog and some plot interface changes ("realtime" checkbox). Mavlink support is already implemented. Anybody interested in helping with this?
File browser doesn't display ü
If a foldername contains the german letter "ü", it won't be displayed in the "Open file" dialog.
Error while building in Ubuntu

FlightPlot Fork
Hi @DrTon
First, many thanks for creating and maintaining this project! It's been very useful to us (PX4 team), and we would like to continue using it. However in several weeks you have not answered to any pull request, and we would like to continue the development (in particular adding/extending support for the ULog file format). So this is not an easy step, but should we not hear back from you, we will keep our own fork at https://github.com/PX4/FlightPlot and release versions for it.
Should you decide to take up development again, you can of course take over and be the primary maintainer. We can also do a shared maintainership if you have too many other things to do, or some other model, but the current state hinders development.
How do you do, how do you extract his latitude and longitude?
Changing a prameter from one processor can change the parameter from a different processor
To reproduce:
- add at least 2 processors
- select one processor
- select the fist parameter and edit the value, do not press enter or leave the field
- select the other processor with the mouse
The first parameter from the newly selected processor will now have the value from the previously modified parameter

Could you please explain how to compile in README ?
I'm newbie of development of flightplot.
I think flightplot is very useful application for pixhawk.
In order to develop with other developer, I think the readme should be more detailed.
Especially, how to compile, how to insert module, and so on....
I just install intelliJ. However, I cannot compile with many problem.
please explain how to compile it...
Apply offset before scale
I think it would be more intuitive if you apply the offset first and then the scale.
So
(value - offset) * scale
instead of
value * scale - offset
For example:
PWM values from 1000 to 2000
(value-1500)*0.001
What do you think?
How to turn OFF Low-pass filter in Expression?
I tune my Optical Flow sensor, and with help of Expression fields I'd like to bring several fields to single scale (for example: optical_flow_0.pixel_flow_y_integral * 100, or optical_flow_0.quality / 100)
But I found out, when I use Expression field - not only expression is calculated, but also LPF is applied somehow, which changes the appearence of the field graphic completely.
For example: this if graphics for optical_flow_0.pixel_flow_y_integral - red - Simple, Blue - Expression.
LPF = 0, should be no filtering, but graphics completely different.
How to turn off the low pass filtering in the Expression field?
Create app bundle for OS X that doesn't rely on Java 6
Adding fields from "Fields List" doesn't work anymore
"Add" in the "Fields List" just adds a Simple Processors
Can't parse certain VTOL logs
Don't know yet if this is a FlightPlot issue or if there's something wrong with a new type of sdlog2 message.
We fail to parse the following logs:
http://dash.oznet.ch/view/kmLXNmL78tTqqLv4b3M2Ka
http://dash.oznet.ch/view/2EryWM2L5d7NkfKp7nwKPW
It always breaks after the new MACS message:
PX4/PX4-Autopilot@e097aff#diff-d92320704a8bd89ce2c077e7824982faR534
@Tumbili : maybe you have an idea? I don't see an obvious error, but it seems that after the MACS message I read an unknown message type from time to time.
Ulog is fully support or not?
I have got a problem to read ulog file ( recorded from pixhawk with px4 firmware), I have try with MAVGCL this application can show the data inside the log but cannot export to google map file, However, I was use FlightPlot to open and generate google map from px4log ( I think it is an old version of px4 log past 6 months ago), now it only able to load but no data on screen and cannot export to google map.
Anyone know how to fix this problem?.

AUR Archlinux package not available
Hi,
On the main page of flightplot, I saw that there is an AUR package for Archlinux. The package is not available nowaday. https://aur.archlinux.org/packages/java-flightplot-git/
It's ok for me to run Flightplot with java -jar but the main page is not up to date.
Please forgive my repeated questions, because I am still a rookie
ULOG: Cannot export KMZ or GPX.
We are using PX4 and with the old PX4log format the export works. But with the new ULOG format the export generates empty 1K files.
General global altitude field offset
- Either specify manually
- Or take starting altitude from some global alt field automatically
Then add offset to all fields we know they contain global altitude.
Should be a checkbox to enable/disable
FlightPlot crashes with empty logfile
By accident I wanted to open a logfile which is presumably empty. Unfortunately this crashes FlightPlot.
It would be nice if an error is thrown instead. The empty logfile is attached.
empty.px4log.zip
Please add a license file
I'd like to suggest something like the 3 clause BSD or MIT license, but obviously its up to you.
