I was wandering if there’s a way to retrieve the current plot area width/height programmatically.
My use case is: I need to display a scatter plot by querying a hufge data set on a server, like “give me all the data between 1st jan 2015 and 1st jan 2016”. This data is stored at a very high “density”, say 1 value per minute. This means that the query mentioned before would yield a HUGE amount of points (circa 550.000), which I do not want, because my chart width is, say, 1000 pixel, so to maintain readability I need the server to SAMPLE the original data and give me, say, a point for each 5 pixels (this means 200 points form the original 500.000+ )
Long story short I need to be able to know the actual plot area width so that i can compute the number of points which can fit on the screen, and query the server accordingly.
The only way I can think of is inspecting the DOM and retrieving the svg plot area width, but I’d prefer something less “hacky”
