Making the graph axes logarithmic

Steps:

1. Right-click the graph window and click Properties.
2. Click the Appearance tab.
3. Click the tab for the axis you want to change.
4. Check the Logarithmic check box to give that axis a logarithmic scale.
5. Click Apply to preview or OK when done.

   A semi-log graph has one axis set to a logarithmic scale, and a log-log graph has both axes set to logarithmic.
