Logarithmic and Normal Scale
Use logarithmic view to view charts with large price variation or longer time scales. Sometimes these are referred to as semi-logarithmic charts because the time scale is not logarithmic.
Logarithmic View

Click the Log button on the toolbar [3] or View menu to display charts in logarithmic scale.

Normal View
Turn off the Log selection on the toolbar (or View menu) to return to normal (analog) scale.
