What was missing, was the navigation bar with a minimap of the entire chart.
Engine API has a cool method, GetHyperCubeReducedData. This returns a reduced set of points based on the zoom factor. If you pass '-1' in the options, the engine will decide for you the depth of the returned data. So if you have one million points of data, the method will still return to you 10000 cells like the hypercube but this time it will be every 100th element.
