| facontidavide wrote:
| In terms of License, it is actually LGPL-3.0 License, the same
| as Qt itself and some of the dependencies it uses.
|
| This means that you can develop proprietary (closed source)
| plugins to create your own custom interfaces to parse data, if
| you want/need to.

| cool!
|
| another neat project based on Dear ImGui that i follow is
| https://github.com/epezent/implot.
|
| i'm a bit of a timeseries enthusiast. if you need something for
| the web, check out https://github.com/leeoniya/uPlot
|
| EDIT: sorry, didn't mean to highjack the thread :(, all glory to
| /u/facontidavide!

| leeoniya wrote:
| i believe it! certainly a viable option in many cases.
|
| any public demo?
| tboerstad wrote:
| I remember you and uPlot from an earlier post :) I'm happy to

|
| I made www.csvplot.com (on top of Plotly.js). I vaguely
| remember discussing using uPlot, but lack of a scatter plot
| stopped me back when.
|
| EDIT: I just tested uPlot again, it's so fast and smooth!
| leeoniya wrote:
| hey, i remember csvplot. scatter is definitely coming at some

|
| a lot has happened since then. i'm now at Grafana, where
| uPlot will power many core visualizations in upcoming
| releases :)
| tboerstad wrote:
| Happy to hear that. I looked up the scatter plot feature on
| Github Issues and I was wondering why there was links from
| Grafana issues in there. Now I know!
| facontidavide wrote:
| Thanks for sharing these links! The big difference is that
| PlotJuggler is a desktop application, not a library.
| leeoniya wrote:
| for sure, i was not suggesting these were alternatives. just
| dropping some links for those interested in timeseries
| plotting.

| Is there a ROS 2 install? I don't see a ros-foxy-plotjuggler-ros
| install. The instructions seem to imply only a ROS 1 install

| I've been using PlotJuggler for a good couple of years now and

| May I ask what's the workflow like with this?

| Looks great! I have been using kst https://kst-plot.kde.org/ for

| plot juggler could be a total substitute. Thanks for sharing
| facontidavide wrote:
| I also used KST many years ago and it was surely a big source
| of inspiration, but I think that PlotJuggler offer a much more
| intuitive interface.
|
| But of course I am biased, as author of PlotJuggler ;)
| rhodozelia wrote:
| If you have experienced the power, capability, and speed of
| kst and then set out to build something better plotjuggler
| must be amazing!
|
| I am not sure of the development status of kst these days I
| think it does everything's it's authors need it to do. Airbus
| may have moved on to an internal tool. The list is very
| quiet. So hopefully it doesn't disappear but I will surely
| check out plotjuggler.
|
| There may be a market for you to sell it to scada and HMI
| companies like Rockwell AVEVA Schneider etc since many of
| them have pretty old school built in plotting functionality

| Can we actually annotate or label data with it?
| facontidavide wrote:
| No. It is a tool to visualize one-dimensional time series.
| Karliss wrote:
| It can also display 2-dimensional xy paths by selecting two
| data series.

| Nice. Non-admin user install would be nice to have.

| Edited to add the full name.

| Ah, sorry. It's been my career for the last ten years, so

| Ha! I haven't seen that before. That's clever.
|
| (sorry, I have no comment on the project itself - I don't do
| plotting-related work much at all)

| Can you save worksheets for repeatable plots ?
| facontidavide wrote:
| Yes!
|
| This is one of the key feature of PlotJuggler. They are called
| "layouts".

| An invaluable tool for analyzing data in robotics! Pretty much
| everyone I know who works with ROS has used PlotJuggler at least
| once.

| This is huge! Respect Captain ! Also the website looks cool.
| facontidavide wrote:
| Thanks :D
| rcmadruga wrote:
| The website indeed looks amazing! Somehow in my mind this was
| only for ROS... Is the support for MQTT and ZeroMQ something
| new?
| facontidavide wrote:
| The core of PlotJuggler is completely decoupled from ROS. ROS
| is supported only through optional plugins.
|
| This means that you can easily extend the number of
| interfaces and protocols adding new plugins, as shown in
| version 3.

| PlotJuggler is amazing! Glad to see it on HN.
|
| I use it for ulog analysis from the open source PX4 autopilot.
| JeanBon56 wrote:
| I use it at my job working with mobile robots it's incredibly

| The fancy website: https://plotjuggler.io/
| mchusma wrote:
| Just popping into say we love your behavior tree project, and

| facontidavide wrote:
| Get in touch, I will be happy to hear more about it :D
| tboerstad wrote:
| I also want to say kudos, I am very impressed by your work!
| mempko wrote:
| Very fancy website. Do you have fancy documentation? This looks

| facontidavide wrote:
| In the app itself there is a visual "Cheatsheet", but this
| particular piece of information is not there.
|
| Give it a try, it should be quite self explaining. If you
| have any issue, get in touch on Github Issues.
| mempko wrote:
| Thanks, will try.
| MoOmer wrote:
| Hey just wanted to pop in and say that the project is great,
| and the code-base is really well structured and easy to follow.
| I dig the Lua plugin support via sol, too!
| tboerstad wrote:
| This looks like an awesome tool, with a lot of neat features.
|
| I went through some hoops to try and build it on my Mac, but
| apparently I don't have the patience to deal with compiler errors
| today.
|
| I would have definitely started testing this tool if there was a
| DMG available.
| facontidavide wrote:
| PlotJuggler author here. I am sorry, but I had no
| opportunity/time to test it on Mac :(
| tboerstad wrote:
| No worries, just wanted to provide feedback. When I have been
| working on robotics, it's been Linux/Windows anyway.
