Graphs can be powerful ways to draw a Graphs can be powerful ways to draw a picture of your data.picture of your data.

Key information can be “drawn” on the Key information can be “drawn” on the graph to make the graph tell even more graph to make the graph tell even more of the story.of the story.

A simple example:A simple example:

Do you see anything obvious?

There seems to be “events” in this time There seems to be “events” in this time series – specifically a significant shift up series – specifically a significant shift up between Dec03 and Jun04 – and between Dec03 and Jun04 – and another shift down about Jul05another shift down about Jul05

Assuming the cause is known (in this Assuming the cause is known (in this case, a large account was won and lost), case, a large account was won and lost), this information can be added.this information can be added.

This is more clear:

Why should I do this with SAS? I could Why should I do this with SAS? I could just import my data into Excel and build just import my data into Excel and build a graph in just a few clicks (well, OK, a graph in just a few clicks (well, OK, more than a few clicks).more than a few clicks).

What if you need to do it every month? What if you need to do it every month? Every week? Every day? For dozens – Every week? Every day? For dozens – hundreds of graphs? – Still want to use hundreds of graphs? – Still want to use Excel?Excel?

First the code to produce the basic graphFirst the code to produce the basic graph

proc gplot data=mydata.random_ts;proc gplot data=mydata.random_ts; plot sales * date / frame plot sales * date / frame haxis = axis1 vaxis = axis2haxis = axis1 vaxis = axis2 cframe = cxeeeedd ;cframe = cxeeeedd ; format sales comma5.0;format sales comma5.0; format date monyy5.;format date monyy5.;run;run;

Now for the annotations – Now for the annotations –

SAS/Graph procedures accept an “annotate” dataset SAS/Graph procedures accept an “annotate” dataset that contains the annotate information.that contains the annotate information.

Annotate information can be very simple or very Annotate information can be very simple or very complex according to your needs.complex according to your needs.

An annotate dataset is simply a dataset that has An annotate dataset is simply a dataset that has certain “annotate” variables in it.certain “annotate” variables in it.

The basic variables are the x,y coordinates to place The basic variables are the x,y coordinates to place the text (or object), the size, color, etc, and the the text (or object), the size, color, etc, and the function to perform (label, draw, etc)function to perform (label, draw, etc)

The annotate data step codeThe annotate data step codedata anno; length color function style $8; length text $200; length x y 8; xsys = '2'; ysys = '2'; hsys = '5'; function = 'label'; set mydata.random_ts; if ( date = &event1 ) then do; x = date; y = sales + 150; size = 4; text = 'ABC Account'; style = 'swiss'; color = 'blue'; position = 'A'; output; y = sales + 75; size = 2; text = 'D'; style = 'marker'; position = 'B'; output; end;

if ( date = &event2 ) then do; x = date; y = sales - 150; size = 4; text = 'Lost Account'; style = 'swiss'; color = 'red'; position = 'E'; output; y = sales - 75; size = 2; text = 'C'; style = 'marker'; position = 'E'; output; end;run;

Variables xsys, ysys, hsys specify the Variables xsys, ysys, hsys specify the “coordinate system” for x, y values and sizes of “coordinate system” for x, y values and sizes of

things (like text)things (like text)

Applying the annotate dataset Applying the annotate dataset is the easy partis the easy part

proc gplot data=mydata.random_ts; plot sales * date / frame haxis = axis1 vaxis = axis2 annotate = anno cframe = cxeeeedd ; format sales comma5.0; format date monyy5.;run;

Last, we want to send this graphLast, we want to send this graphin an email – using SASin an email – using SAS

%let mygraph = mygraph.gif;filename gsfile "&mygraph";goptions gsfname=gsfile gaccess=sasgastd;proc gplot data=mydata.random_ts;…run;filename dummy email;data _null_; file dummy to = ("wjsmith1@fedex.com") subject = "Sales Region Report" attach = "&mygraph“ ; put 'Attached is the Sales Region Report.'; put 'If you have any questions feel free to call.';run;
