Solved: SAS data into JavaScript

dstephens22 · Posted 09-22-2021 01:22 PM

Hi I am using a Google pie chart as a stored procedure in SAS VA.

I can get the JS to run fine but I am trying to determine how to add sas values in place of the JS addrows data. I tried using SAS macros but it doesn't work. Is there a way to automatically add the data values from SAS into the data.addRows in JS?

I want to replace the below with SAS values not the hand entered text.

Thanks in advance. I have been all over Google search.

var data = new google.visualization.DataTable();

data.addColumn('string', 'Topping');

data.addColumn('number', 'Slices');

data.addRows([

['Created Cards', 7],

['Cards Printed', 1],

['Sent Emails', 1],

['Unique HCPs', 1],

['Engaged', 2]

]);

Have you looked at Data Driven Content Objects in SAS Visual Analytics? Seems tailor-made for the thing you want to do: drive a 3rd-party visualization but with your SAS report data.

Thank you for the quick response. Unfortunately I do not have SAS Viya yet. I should have added I am on SAS 9.4.

That looks like a great approach, once we have it.
