I am using TChart Pro v2014 with XE7. I need to show a lot of points in my VCL application (like hundreds of thousands) and be able to zoom, but it is painfully slow.
I came accros this [forum thread|] which describes how to use DownSampling class included in TChart to improve performance. Which header I have to include to be able to use it? When I try to search for "downsampling" in TeeChart installation folder only receveived results are in FMX headers.
