Steve I forgot to put my name at the bottom of my last post. Maybe you could substitue this instead. Jad Succari writes >How do create a log axes? There is a function LogScale that is available in the Standard Package Graphics`Graphics`. This can be used as a setting for the tick mark option of Graphics objects. Rather than create log axes specifically it is often easier to use one of the commands like ListLogPlot which come with log axes (using the LogScale function). In[1]:= <<Graphics`Graphics` In[2]:= ?LogScale LogScale[xmin, xmax] gives a list of "nice" values between xmin and xmax suitable for use as tick mark positions on a logarithmic scale. LogScale[xmin, xmax, n] attempts to find n such values. In[2]:= ?LogListPlot LogListPlot[{y1, y2, ...}] or LogListPlot[{{x1, y1}, {x2, y2}, ...}] generates a plot of Log[yi] against the xi. In[2]:= LogListPlot[ {10^2, 10^3, 10^4}] Out[2]= -Graphics- Tom Wickham-Jones WRI
