proc sgplot - plot multiple variables on one graph

[using EG 9.4]

I have a data set that looks like this:

product sale_date   price 
abc     01/01/2018  1.13 
abc     06/01/2018  1.29 
abc     02/02/2018  1.23 
xyz     02/01/2018  1.54 
xyz     08/01/2018  1.58 
xyz     03/02/2018  1.41

And I need to plot two series (one for each product) on a pbspline plot of "price vs date".

I have tried a number of variations but am unable to get two separate series. Here's what I used most recently:

ods graphics on / height=600 width=900 noborder;
proc sgplot data=work.product_daily_sales(where=(product IN ('abc', 'xyz')));
by product;
pbspline x=sale_date y=price / legendlabel='company1' markerattrs=(symbol=circle color=blue size=5) lineattrs=(color=blue);
pbspline x=sale_date y=price /  legendlabel='company2' markerattrs=(symbol=circle color=red size=5) lineattrs=(color=red);
xaxis label='Date';
yaxis  label='US Price ($)';
title 'Sales Price by date of sale';
run;
quit;

Basically, I am comparing prices for a similar product to two different companies and I need to show the difference in pricing on the one graph.

The above code gets me closest to what I want but displays two graphs.

Can anyone help?

Thanks in advance.

You don't want a BY statement. Instead what you want is a GROUP= option on the PBSPLINE statement that specifies PRODUCT as your GROUP variable.

pbspline x=sale_date y=price / group=product markerattrs=(symbol=circle color=blue size=5) lineattrs=(color=blue);
xaxis label='Date';
yaxis  label='US Price ($)';
title 'Sales Price by date of sale';
run;

Thanks. I was almost there.

In cases like this, how do you change the marker and line attributes of the different series (products in this case)? So they're both not in blue.

You could list them in the STYLEATTRS statement but I prefer using a data attribute map. I just find it simpler and cleaner to deal with.

There's examples here:

OK. I read about them but wasn't too sure that's what I needed. Thanks for your help.
