Custom candlestick plots and tool tips:

ImPlot + ImGui Tables API:

Both of these have been added to implot_demo.cpp

Robot simulation GUI for FIRST robotics with multiple plots and drag and drop everything.

@PeterJohnson , I'm curious how you got the linked axes working and if it is bidirectional. This is a feature I've wanted to implement.

Some things DearPyGui users have made:

[PeterJohnson]

@epezent It is not bidirectional. I just use SetNextPlotLimitsX() to force the X axis on the second plot to follow the first. Bidirectional is a good idea. I think how I would tackle that is to do the SetNextPlotLimitsX() on the other plots only when one of them is actively being dragged (there would be a 1-frame delay to updating the first plot when you dragged the second plot, but that's hardly noticeable). However, to do this, I would need a method to detect when a plot is being dragged by the user. Is that exposed in implot_internal.h?

Not sure if this one counts, but since I will be using this library to make an application for USB oscilloscopes, I've been doing some experiments where I plotted some (generated) signals into heatmaps in order to visually differentiate the random noise from the real signal. Here's the result:

I want to take this chance to thank @epezent and all the colaborators of this project for this amazing library. Sincerely, thank you all for your amazing work ❤️

@marcizhu Does the sample increase the "weight" and time decrease it? It will be great to have a "light" version in the demo...

[marcizhu]

Indeed, every "hit" of the signal increases the histogram value by 1. I also keep a variable with the maximum value on the histogram at every given moment so that the colors cover the maximum possible range, but using time would also be a solution if you want a "fade out" effect once the signal disappears.

I can post a snippet with the code tomorrow if you guys want :)

@marcizhu, that's cool! What's the performance like? I didn't really optimize heatmaps for high density display, but it'd be an easy fix if it's needed.

[epezent]

Also, @marcizhu, feel free to submit a PR adding a minimal example to the demo :)

"Fade out" effect will help you not only when signals disappears but generally when changes it's nature and a plot persistence factor will help you to track signal modulations

@epezent The performance is really great: the histogram has a size of 1024x256, and rendering it on a 1280x720 window (the screen is 2560x1600) on a MacBook Pro 2018 (so not the best GPU in the world) I get 60-80 frames consistently. If we take into account the fact that my code is just a quick & dirty demo and it is not optimized at all, I'd say the performance is more than acceptable :)

Also, @marcizhu, feel free to submit a PR adding a minimal example to the demo :)

Great! I will be opening a PR in a few days. Right now I'm a bit busy with university and exams, but once time allows I will definitely open a PR :+1:

@ozlb That's totally true. I will try using time instead of just tracking the maximum value of the histogram and if the end result looks nice, I will add that to the demo instead :D

Here is an application to display seismic data, thanks to the implot project.

My deep reinforcement learning playground, heavily using different kinds of plots. Big thanks to implot!

A quick little toy I put together while working on some DSP algorithms.

Desktop+ is a tool to bring your desktop and more into SteamVR. A recent addition is the Performance Monitor. ImPlot is used here to render the frame time graphs. This is pretty basic as far as plotting goes, but I just wanted something to render neat looking graphs in Dear ImGui and ImPlot fit the bill nicely. Thanks for that.
