Cool, nice to hear that. I didn't know the sound signal is such a help :)

Thanks Artur. Golang+Postgres on backend, React+Redux on frontend. Golang is really powerful for such heavily parallelized app as TensorCharts

If you are interested in the basic concepts on which TensorChart (TC) is built, check out these mini-tutorials explaining heatmaps (the red/green/blue squares) and TC features

Have you tried react-stockcharts? Awesome charting library...pure SVG, or hybrid mode with html canvas, open source, developer is very responsive.
