> 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:
> {code:java}
> let(a=array(1,2,3),
> b=array(4,5,6),
> zplot(line1=a, line2=b, linec=array(7,8,9))){code}
