SGPLOT - graph shape square

[Lou523]

How do I get SAS to print an ellipse plot as square, size n by n? Regardless of axis range for either x or y, each axis should have the same length (ie. 5") on the figure generated / printed. SAS ellipse plots printed in landscape are NOT the same (different angle of rotation, major and minor axis are not perpendicular, etc) as ellipse plots in a square. SAS ellipse plots in landscape are not correct - only distortions of an ellipse plot in a square.


proc sgplot data=WORK;
scatter x=afp y=ue3;
ellipse x=afp y=ue3 /alpha=0.05;
run;


Thanks,
Lou

Hopefully one of the sgplot experts can give you an answer.

But, if you can't find a way to do it in sgplot, you might give gplot a try - you can specify a length (in inches) in the axis statements, and it will generally try to honor that (thereby giving you a way to keep the axes & your plot proportional).

As an example, below is the code for a "spiral" time-series plot - I wanted to keep the 2 axes proportional (whether title statements got added, etc) so that the spiral would not look "squished".

Thanks - I'll give this a try. Lou

Currently, the SG procedures do not support equated axes but the Graph Template Language (GTL) does. Here is a very simple example to get you started. Details for the template language can be found in the documentation.

Thanks!
