Click the Scale tab to choose either a linear or logarithmic scale for the X- and Y-axes of an X–Y plot. The scales of the X- and Y-axes are independent. By default, ABAQUS/CAE uses a linear scale for both.
To customize the type of axes of an X–Y plot:
Locate the Type options.
Select Options
XY Plot from the main menu bar or click 
in the toolbox; then click the Scale tab in the dialog box that appears. Options that control the X-axis are at the top of the page, and options that control the Y-axis are at the bottom of the page.
From the X-axis Type options, click Linear or Logarithmic to choose the scale of the X-axis.
From the Y-axis Type options, click Linear or Logarithmic to choose the scale of the Y-axis.
Click Apply to implement your changes.
The axes of the X–Y plot in the current viewport change to reflect your specifications.
Your changes are saved for the duration of the session and will affect all subsequent plots in this mode.
