Linear or Logarithmic Scaling

You can apply linear or logarithmic scaling to the x- and y-axes by choosing the appropriate option in the Global Options dialog box.

Scaling the X-Axis

The x-axis must be a non-reference axis in order to specify logarithmic scaling. In addition, the scale range for the x-axis must have no negative values.

The X-axis scale option does not appear in the Global Options dialog box that appears for reference axis graphs with time line scaling.

Scaling the Y-Axis

The y-axis must be a non-reference axis in order to specify logarithmic scaling. In addition, the scale range for the y-axis must have no negative values.
