Does the chart support downsampling on the graphics? #621
Description
First of all, thank you for your great work on this project!
I really appreciate all the effort and time you've put into it. This is a great project.
What I’d like to ask is whether the chart performs downsampling on the graphics. During my usage, I noticed that when I use it to draw a line chart, even if I zoom the chart out to be very small—so that the lines are all squeezed together—the number of vertices (data points) remains unchanged according to my debugging observations. This results in unnecessary performance overhead.
