Improved Plot widget for displaying audio data

[soulthreads]

I've implemented a Plot widget that can show a grid, has custom tooltip support, logarithmic x-axis scaling, is able to draw multiple sources on the same plot, and also supports selection.

All of this was really useful for me when working with audio and ultrasonic data, since I often need to compare signals, show spectrums of the selected part of the signal, and know what value it has at a particular point.

The code is located at https://github.com/soulthreads/imgui-plot
It is written in C++11 style, but if folks really need it, I can scale it down to C++98 with no problem.

Here are some samples of what it looks like:

I hope you will find it useful, and feel free to file issues if you have any problems with it!

Closing this now. Thanks for sharing this!

Nowadays I would assume most people would be using ImPlot to solve this, but yours came first :) It's also been listed in https://github.com/ocornut/imgui/wiki/Useful-Extensions at the time we opened that page.
