    stock chart non-linear y-axis

    A chart displays columns representing #shares traded for a group of 20 stocks along x-axis. Because the displayed values span a wide range (some columns are 1000x larger than others) the small volume stocks are hardly visible. What is needed is a way to make Y-axis non-linera; however, a log scale is useless because of the enourmous compression that takes place at the higher end of the y-axis.
    Is there a way of displyaing non-linear values at a scale less than allowed by log values? Web-based stock charts do this regularly, for example see chart displayed on Yahoo finance of Apple Computers (symbol AAPL)

    http://finance.yahoo.com/q/bc?s=AAPL&quicken=2

    Any help here? Thank you.

    That chart has a Log scale!
    However, it displays y values rather than Log(y) on the axis

    Should be possible with Bovey's XY Chartlabeler (www.appspro.com)

    Rob's Labeler, plus transformed data allowing an arbitrary scale. Look here:

    or at the Arbitrary Log Axis example on Tushar Mehta's site
