      Description

      The Solr Zeppelin interpreter (https://github.com/lucidworks/zeppelin-solr) can already execute Streaming Expressions and therefore Math Expressions.  The zplot function will export the results of Solr Math Expressions in a format the Solr Zeppelin interpreter can work with. This will allow results of Solr Math Expressions to be plotted by Apache Zeppelin.

      Sample syntax:

      let(a=array(1,2,3),
          b=array(4,5,6),
          zplot(line1=a, line2=b, linec=array(7,8,9)))
