  • Density of datapoints over time


    If you have a lot of measurements on a time axis you can use the binning functions of Spotfire® to look for the "density" of datapoints per bin.


    You have to bin the x and y axis, but also the "Marker by" by both, the X and the Y axis binnings.

    If you don't need it to be interactive, you can of course also pre-calculate the bins in calculated columns.

    I used these:

    BinByEvenIntervals([date],30) --> X
    <BinByEvenIntervals([value],30)> --> Y
    <BinByEvenIntervals([value],30) NEST BinByEvenIntervals([date],30)> --> Marker By
