I have a dataset (called data_customers) that is structured like this (with several more customers and companies) and I'm trying to make a scatter plot for each customer.
Date

Since there are a ton of customers that I need to create these plots for, I feed the SGPLOT procedure through a macro loop for each one so that each dot in the final scatter represents the date and value with the color of the dot representing the color of the company. However, in the above example, since the plot for Customer B only contains one customer, the color picked for Company D ends up being the same as the color picked for Company A in the plot for Customer A. Is there a way to manually assign colors to each value in the legend so that these colors end up being consistent across charts?
proc sql;
select distinct customer
into :customers separated by "|"
from data_customers;
%let customer_count = &sqlobs.;
;quit;
%macro plot();
%do i = 1 %to &customer_count.;
%let current_customer = %scan(&customers., &i., "|");
ods graphics on / noborder width=10in height=5in;
proc sgplot data=data_customer (where=(customer = "¤t_customer."));
scatter x=date y=net_price / group=company filledoutlinedmarkers markerattrs=(symbol=circlefilled);
title font = "Times New Roman" "¤t_customer.";
yaxis max=7 min=0 label="Value";
xaxis display=(nolabel);
keylegend / position=n title="" noborder;
run;
%end;
%mend plot;
%plot();
