I have a chart with a Line Series that I am adding data to. I am using the CategoryDateTimeXAxis and NumericYAxis for my axes.
I've noticed that when I'm adding points to the series it down-samples at about 1200 points. I would like to adjust this. Is there a way to set this? Also is there a way to change the down-sampling algorithm?
This happens whenever 2 or more values fall within a single pixel, so the threshold is a combination of data volume and chart's size. There's currently no way to change this threshold or use a custom algorithm. Are you having any issues with the current algorithm? We're always open to suggestions for improvement.
Thanks for your reply.
That is about the same rate I was going to down sample so that is great. I would like to know what the down-sampling algorithm is. I need to know this because, in my case, it is important that certain points of interest are not decimated out of the data series. Is it a simple decimation or are the max/min points being kept or is an average being calculated, ....?
