EXAMPLE 21 GIF Animation
Purpose: This example demonstrates a very powerful, yet little-known feature of SAS/GRAPH: animation.
If you want to plot some trigonometric functions, there is nothing really difficult about doing that. First, you could write a DATA step to loop through the desired angles, and calculate the value of the function or functions at each angle. For example, the following code loops from 0 to 720 degrees, and calculates the sine and cosine for each angle.
data mydata;
length id $10;
do Angle = 0 to 720 by 15;
radians=Angle*(atan(1)/45);
Value=sin(radians); id='Sine'; output;
Value=cos(radians); id='Cosine'; output;
end;
run;
And then you could use PROC GPLOT to plot the values.
