Hi,
I'm using the heatmap to render a spectrogram with nearly 1 million points (256x3700) and I'd like to be able to update it dynamically to improve loading as well as well live stream for real-time. Is this possible to do with delay < 1s? I've suspect that even updating a single point and calling chart.redraw() redraws the entire chart because it takes about 10s to complete. Is it possible to only re-render the points that have been updated?
Thanks!
