weird behaviour with scale object/incoming data

    Hello
    I am getting out-of-bound results when using the scale object. I take data from the net and they have to be scaled but for some reason the result is out of the limits. I am copying here the scale part (the whole patch is for too big and requires installing some Java objects)
    When doing a forced update of the data (a forced bang). I get a good result. Something weird happening?

      you're setting a high and a low. If you're getting data that's outside the bounds that means the price hits a year low or a year high, right?
      What I'd do is feed it through, compare it to the year high and year low, and then update this before scaling - that way it will adjust properly.
      Alternatively, just clip using zmap instead of scale?

      It seems that when I update the data, the dayprice comes in but the yearlow and yearhigh are delayed. As such, the dayprice is compared to the wring limites and gets out of bounds. I have tested with the pack object to see how fast the data come in but they always come in late and hence I get wrong results. Using pipe I cannot solve this so as it seems. Any suggestions?
