  • Ways to compress graphicly displayed data

    I've been working on a data logger and I'm fairly pleased, although I still have the shifted scale ticks and numbers to deal with.

    plotting starts on the extream left untill it "hits" the right side, from there untill the end of plotting the image and time scale scroll left. I would like to be able to time compress the data and currently display the mean of 5, 10 or 100 samples. I doubt that this is the best way, I wonder perhaps is a vertical line representing max min values in the selected time might be better.

    Are there standard ways to do this or does anyone have any suggestions?

    Put this in Programming section?

      Not really, my question is not about programming, it's about visual representation of data, and thers no section for that.

        Why not leave the left 10% of the graph as an average.

        So for example (using rounded math):
        • if your main recording interval is seconds
        • the width is of the graph is 1000 pixels
        • the right 90% (900 pixels ) would represent the last 90 seconds
        • Each pixel on the left 10% (100 pixels) would also scroll, but represent the average over the last x seconds (lets say 5 seconds)
        • So the 10% section would represent a scrolling 500 seconds (~8 mins)

          George I'm a afraid I'm much to simple a soul to either programme or understand such a display.

          Nevertheless in the 10% section you're still proposing a simple mean and something tells me thats not optimal.
