Scaling Axes

Range of Values

You can also scale axes by specifying a range of values. Notice the default scaling of the vertical axis in the plot below.

Plot with default vertical scale.

To scale the vertical axis from 0 to 100 in increments of 50, for example, you can use the VAXIS= option shown in the PROC GPLOT step below.

     proc gplot data=clinic.therapy1999;
        plot aerclass*month / haxis='01' '06' '12'
             vaxis=0 to 100 by 50;
     run;

The modified vertical axis appears in the plot below.

Plot with optional vertical axis.

When you specify a range of values, be sure to scale the axis in workable increments to accommodate the smallest and largest data values to be plotted.
