Hi Guys
I have a problem with the graphic here, when i select to display the graph in natural log scale through the modify axis menu, the axis becomes something that doesn't make sense.
The graphs are attached here!

If you set the axis range to Auto, or manually set the minimum range to something positive, it should work fine.
Added a bit later: I tried setting a log axis on a graph with Autoscale from Zero in 6.20 and 6.00 and it worked fine. Apparently, Igor is doing the Right Thing- ignoring the Autoscale from Zero setting when switching to Log mode. In response to your query to support@wavemetrics.com, I have asked you what version of Igor you are using.
