I am trying to plot a large list of {x,y} coordinates, with x ranging from 1  150 and y ranging from 1 to 250. I need the yaxis to have the tickmarks as follows:
1,2,4,8,16,32,64,128,256,512,etc.
I can get that far just fine, but the problem is that I need those tickmarks to be evenly spaced. So, in other words, I want the yaxis to have a logrithmic scale  base 2.
I've experimented with this, and have only been able to get this type of yaxis when I define it as a function of the xaxis. For example, the xaxis would go from 010 and the yaxis would be 2^0, 2^1, 2^2, 2^3, ... 2^10. This doesn't give me the xaxis that I need. I want the xaxis to be independent of the yaxis so I can plot the independent points.
As a frame of reference, at http://astro.uchicago.edu/Computing/HPCC/Milestones/milestone3.htm, there is a picture of a graph that has the xaxis scaled in this fashion, independent from the yaxis. That's not exactly what I need, but it gives a nice visual of the idea.
I'm spinning my wheels...please help...
