be careful with LogLinearPlot

Needs["Graphics`Graphics`"]

Hi, I noticed that it is very easy to misinterpret the results of the
LogLinearPlot command from the Graphics.m package. For example:

LogLinearPlot[ArcTan[w],{w,.001,1000},PlotRange->{{0.001,1000},{0,Pi/2}}]

will produce a smooth but incorrect graph. You can tell by trying:

LogLinearPlot[ArcTan[w/1],{w,.001,1000},PlotPoints->500,
PlotRange->{{0.001,1000},{0,Pi/2}}]

it looks like LogLinearPlot is very silly. 500 points is not an efficient
way to do the graph. Any comments? Is out there a *good* package for log
plots?

Thanks
