For line 177, error message: no known conversion from 'const gl::GLboolean' (aka 'const glbinding::Boolean8') to 'int' for 2nd argument

Replacing GL_TRUE with GLFW_TRUE will make it compile.

ImGui v1.84 removed there gl3w code, because it is now embeded.
... also, having to have imgui and implot be in the directory above is kinda bad, imho.

Hello,

Which version of ImGui was it used in this project?

I am following the steps, provide in the README, to compile the project and I am getting some errors compiling ImGui.

COMPILATION STEPS

mkdir root
cd root
git clone https://github.com/epezent/implot_demos
git clone https://github.com/epezent/implot
git clone https://github.com/ocornut/imgui

ERRORS:

Maybe we can update the compile steps forcing the clone of ImGui with the correct version.

Hi,
Is there a way to keep track of specific plots, so if I have stocks going on, and I'd like to keep latest candle in middle of screen (tracked) how can I do something like ImPlotTrack and passone the plot name maybe so it keeps focus on it? Not sure how something similar can be achieved. Thanks

Just tried to build with today's git head of imgui/implot/implot_demos with gcc 10.3.0 and see:

Hi!

I would like to make an example "stocks" running in real time. Do you have any idea how this could be done? I'm interested in top down ideas.

As far as I understand we can get data from yahoo finance all the time if we access it every few seconds. We also need to think about how to redraw the candlesticks each time. Also we need some kind of storage, otherwise all data might not fit in.

In general, I would be glad to get any ideas for an example and articles, based on which I could make the example realtime.

I am using ImPlot to plot the spectrogram of audio recorded from microphone in real-time and it works fine. It is based on the demo in this repo.

What would be the most efficient way to have the plot scroll in real-time with new data entering from the right ?

I tried using ImPlotHeatmapFlags_ColMajor so as to have the spectrogram bins in consecutive memory in C/C++ with the idea of doing some movement of elements in the array. But I was unable to get ImPlotHeatmapFlags_ColMajor to work correctly. I only changed the order of data in the array and enabled the flag with no other change.

BTW thanks for developing the awesome ImPlot library

While compiling tests/benchmark.cpp using clang-cl (ver. 16.0.1), I'm facing this issue: ocornut/imgui#6386
Errors from clang-cl:

This has been fixed in: https://github.com/nlohmann/json/pull/3082/files. The gist of it was simply:
