I have an example with about 80,000 data points that I would like to display in a heatmap. My web application hangs up indefinitely when I try to build/display this. HighCharts has a ‘Large heat map’ example, where it uses an HTML 5 canvas instead of svg for large data sets. Is it possible to implement this in vaadin somehow also?
Hi,
Vaadin Charts make pretty much no customizations to the script running in the browser (HighCharts) so I think using the canvas rendering hack they use in the demo should be pretty easily usable with it too.
BTW. If you are interested about geographical heat maps, check out the v-leaflet-heat from the Directory. On my macbook pro it pretty easily rendered million points. In real network that would naturally use some bandwidth already 
cheers,
