I am trying to synchronise my navigator to my chart when its zoom is at max range. As you can see in the screenshot below, my navigator is at max range but the dips in the series of it do not sync up with the main chart. I believe this is because there is data grouping on the navigator, but not on the main chart. However, if I disable data grouping on the navigator, it just renders completely blank.
I don't understand why the main chart can render in less than a second with no data grouping, but the same doesn't seem to be possible for the navigator? Can anyone give a perspective on this?
