Hi, Roger, off the topic, if you are not using scatter plot for quite good resolution when you're dealing with such large points, you might want to give ECharts.jl <https://github.com/wlbksy/ECharts.jl> a try. all your need is use "ec_scatter_large" function instead of using " ec_scatter" when you're dealing with large scale scatter plots.
