Interesting tool but couldn’t discern the interface from the README.

On a side note, does anyone have any recommendations for C++ plotting libraries that integrate nicely with Eigen matrices/vectors? Even better if it is usable through lldb when breakpoints are set. I’m trying to recreate my workflow in matlab where you can set a breakpoint at some point in the code and visualize through different plots the variables when writing an algorithm. I find this makes matlab very nice for prototyping and the lack of this workflow becomes a real pain point when we go to convert our matlab implementation to a more performant C++ implementation.

ImGui won't work in a breakpoint, but on the other hand it's more or less designed to do what you want, in the sense that there is not a lot of ceremony required to create a slider to adjust a variable (unlike, say, Qt, where you to need to wire a few things). So if you can keep your program running, you can use Dear ImGui as a sort of custom debugger front end. Many people in the video game industry use it to do exactly that.

The README isn’t particularly helpful, but the API is rather self-explanatory looking at the header. Eg, this line from the README:

    ImGui::PlotBar("My Bar Plot", values, 10);

values is a pointer to 10 floats.

It depends on your debugger. Visual Studio has a plugin model to support this, but it involves writing a server and a client, and serialising all your data over a socket.
