lognplot's Issues

Option to link plot axis

Given several plots, it should be possible to link the x-axis to allow analysis across different plots.

Windows build: ease the pain

This issue aims to gather all troubles on windows when running lognplotgtk

Tasks:

• Windows build procedure must be document
• Several in app icons are missing on windows
• Dragging a signal loses the mouse cursor
• hdf5 support on windows
• lognplot icon is missing in the top-left corner of the windows window

Any other issues?

Add feature to load HDF5 file on drag drop into application

We can export data to HDF5 format, but we need to import this data back as well. This can be handy for later analysis.

Add option to tail customized timespan

We have options for tailing last time spans. Add an option to popup and query a timespan to tail.

Wrong instruction for installation: cargo run vs. build

Hi,

just a minor notice: in the README you wrote

$ cd lognplotgtk
$ cargo run --release

but it shoud be

$ cargo build --release

right?

Thanks for that awesome program!

RFC: simulink adapter

It would be cool to add a simulink adapter in some way.

I can see multiple ways on how this could work:

• integrate lognplot client into a simulink block, and make this available as a library block
• Use the simulink C-API to auto discover all signals in the model and subscribe somehow to changes

Any other ideas how this could work? What would be a good way to do this?

Horizontal mousepad scrolling on MAC

On mac, you can scroll horizontally on a track pad. This should pan the view horizontally.

Feature: text logging

Figure a way to visualize text messages, like for example log message or state enums.

Add ads adapter

Add a ADS adapter which will download signals from beckhof ADS and sends them into the lognplot tool.

Crash when adding plots

The lognplotgtk application crashes when adding plots to the "extra" 2x2 plot window.

To reproduce:

• Run application cargo run --release
• Open extra plot window by clicking View -> New 2x2 plot window
• Drag plots to all 4 plots in the new window.
• Keep adding plots until it crashes (usually after 5 or 6 in total)

Test environment:

Add MQTT adapter

Add a python script which subscribes to all MQTT topics and pushes them on to the lognplot tool.

Points of interest:

• what happens when a topic is added?

The file can be added to the demos folder, or in a new folder named adapters.

Interface with arduino serial plotter

There are several options for plotting data with arduino.

Having compatibility with arduino would extend the user base.

See this link with an overview:

https://arduino.stackexchange.com/questions/1180/serial-data-plotting-programs

Not sure how this should work, but there must be a good way to make this work properly.

Add trigger signal type

To be able to trigger the plot to a certain signal, a trigger signal comes in handy. This signal should be usable in the plot to select as a trigger.

Drag'n'drop area non-responsive

On Fedora 31 with python3 (3.7.5) and python3-qt5 (5.13.1) the drop area is not working. The signals in the list get nicely updated, but I cannot plot them.

Support ipv4 / ipv6 everywhere

There are some issues with mixing ipv4 / ipv6.

Check:

• lognplot rust ipv4 / ipv6 server support
• lognplot rust client ipv4 / ipv6 support
• lognplot python client support
• lognplot python server support

For now ipv4 is used, but it should work seamless.

Storage backend using RocksDB database

The RocksDB library provides a persistent key value store. Keys and values are arbitrary byte arrays. The keys are ordered within the key value store according to a user-specified comparator function.

Implementation is in C++, there are rust and python binding available. The database is stored in a single directory (not single-file).

Add integration with hawktracer

This project can trace data from an application, as a library.

https://github.com/amzn/hawktracer

Create an example adapter to visualize this data.

Saving configuration of signal analysis look'n'feel

Another feature request:
gtkwave features a 'save' file that stores the configuration of the user interface at any savepoint. Restarting gtkwave with a previously saved configuration gives you an identical setup. This is useful for repetitive measurements / introspections, as it may be quite cumbersome to re-configure a complex aggregation of signals and plots. (For the insiders; referring to the embedded debugger UI.)
So, I think it would be nice to be able to define a subset of the available signals and store that selection, together with the visualization properties and corresponding plot configuration. The data source may have (slightly) changed, but its values are then projected into the same look'n'feel.

swvviewer on crates.io

Hi!

Do you plan to release the ITM code as a lib on crates.io somehow?
I am very interested in it! I could write it myself ofc, but not sure that's worth it, but I have no interest in a binary crate :)
Also I only have interest in the protocol itself, as we have all the debug probe stuff down already.
Do you think this is a possibility?

Best,
Noah

Crash when zooming in all the way

Lognplot crashes if you zoom in as far as posible. Application stops responding, and quits after a while.

Feature request: adapter for icecream (distributed computing cluster)

Distributed compiler with a central scheduler to share build load:
https://github.com/icecc/icecream

icecream comes with an 'icecream monitor' to visualize the active workload and distribution among the connected clients. It would be nice to visualize that in lognplot as well. The monitor works by listening on a UDP port. I guess it would be doable to translate the info to lognplot.

how to properly use rust network client

I'm trying to write a program that uses the TcpClient, but I had to modify mod.rs to expose it properly in order for my application to use it. The modification required is:

diff --git a/lognplot/src/net/mod.rs b/lognplot/src/net/mod.rs
index bd488aa..b20e910 100644
--- a/lognplot/src/net/mod.rs
+++ b/lognplot/src/net/mod.rs
@@ -9,7 +9,7 @@
 //! - Read data from file
 //! - Demo data (random values)
 
-mod client;
+pub mod client;
 mod payload;

Am I doing something wrong here (I'm not a very experienced rust programmer)? What is the proper way for an application to use the TcpClient structure to communicate with the GUI?

Plotting NaN Values has strange behaviour

There you go!

Feature request: influx DB line protocol adapter

The influx DB line protocol is described here: https://v2.docs.influxdata.com/v2.0/reference/syntax/line-protocol/

It would be great to have a python adapter which can handle this line protocol and forward the data to the lognplot gui.

Dependend crate futures-io 0.3.1 does not compile

I am not yet too familiar with rust to find out how to explicitly try an older version of futures-io. That would likely work as it seems to be an indirect dependency.
Or is my Rust to rusty..? I guess 1.39 is not too old yet...

Give meta chart real time timestamps

Support for mixed-signal plotting?

I read through the list of related tools in the README. Since this is still low-profile, I take the liberty of writing down 2 feature request / wishes. Those are the things that at least partially lack in either one of the tools mentioned.

• mixed-signal support; gtkwave to some extend can plot both digital and analog signals, but has poor support of handling the analog signals
• math operations; this will likely hurt performance, and I am not sure if it combines well with the massive-data-support already built-in. But, in practice it is very useful to apply some math operation to the signal before plotting; either scaling the (analog) signal, or masking (bits) of a digital signal.

Maybe there is a better way to gather feature requests?

New Release to crates.io?

In order to use the Rust client in external projects, we need a new release to crates.io because the current 0.1 release do not have the TcpClient.

Thank you

Scaling horizontal axis resets vertical axis

When you zoom in / out on the horizontal axis, the vertical axis gets reset. This is somewhat unexpected as you loose your focus point.
