Error Message - Graphs

[allison93]

What am I entering wrong in the following?  I am trying to make a graph of factor 2 vs factor 1 and factor 3 vs factor 1

386 proc plot;

387 plot factor2*factor1=brand factor3*factor1=brand;

ERROR: Variable FACTOR2 not found.

ERROR: Variable FACTOR1 not found.

ERROR: Variable BRAND not found.

ERROR: Variable FACTOR3 not found.

ERROR: Variable FACTOR1 not found.

ERROR: Variable BRAND not found.

You missed to write the dataset to be used.

Without data the variables are unknown.

The syntax should be like:

proc plot data=<my_data> <more options> ;

PROC PLOT is still supported? I would suggest trying PROC SGPLOT instead, but the syntax is different.

For some procs, if you don't specify a data=, then it will use the last active dataset.

Here's an example:

proc sort data=sashelp.class;
by age;
run;

proc plot;
plot height*weight;
run;

But I would recommend always specifying the data=, so there is no uncertainty, like:

proc plot data=sashelp.class;
plot height*weight;
run;
