Let me put in a plug for the residual chart. Decades ago, before ODS Graphics, SAS produced "ASCII graphics" or "printer plots" composed of characters in a nonproportional font. Near the end of my career at SAS, I realized that PROC REG still had an ASCII graph. I replaced it with ODS Graphics. Bob Rodriguez provided a great deal of oversight.

PLOTS=RESIDUALCHART
PLOTS=RC
produces the residual chart and enables you to specify residual-chart-options. This chart displays studentized residuals and Cook’s D in side-by-side bar charts. This chart is also displayed when you specify the R option in the MODEL statement.

Unlike most graphs, the height of this chart can vary as a function of the number of observations that appear in the chart. You can specify the following residual-chart-options to control the height and other aspects of the chart:

COMPUTEHEIGHT=a b
CH=a b
specifies the constants for computing the height of the chart. For n dimensions, intercept a, slope b, and maximum height max, the height is min(a + b (n + 1), max). By default, COMPUTEHEIGHT=150 15 1650. Thus, the default height in pixels is min(150 + 15(n + 1), 1650). The default unit is pixels, and you can use the UNIT= residual-chart-option to change the unit to inches or centimeters.

MAX=max
species the maximum number of points to display in each chart. When the number of points exceeds max, charts of up to max observations are displayed until all observations are displayed.

SETHEIGHT=height
SH=height
specifies the height of the chart. By default, the height is based on the COMPUTEHEIGHT= option. The default unit is pixels, and you can use the UNIT= residual-chart-option to change the unit to inches or centimeters.

UNIT=PX | IN | CM
specifies the unit (pixels, inches, or centimeters) for the SETHEIGHT= and COMPUTEHEIGHT= residual-chart-options. Inches equals pixels divided by 96, and centimeters equals inches times 2.54. By default, UNIT=PX.

UNPACK
suppresses paneling. The studentized residuals and Cook’s D are displayed in separate charts. When you specify the UNPACK residual-chart-option, residuals, standard errors, and other values that go into the computations are added to each chart.
