The PLOT Procedure

Example 5: Plotting Data on a Logarithmic Scale

Procedure features:

PLOT statement option

HAXIS=

This example uses a DATA step to generate data. The PROC PLOT step shows two plots of the same data: one plot without a horizontal axis specification and one plot with a logarithmic scale specified for the horizontal axis.
