A post on [StackOverflow](http:\/\/stackoverflow.com\/questions\/28725604\/streamgraphs-dataviz-in-r-wont-plot) asked about using a continuous variable for the x-axis (vs dates) in my [streamgraph package](http:\/\/github.com\/hrbrmstr\/streamgraph). While I provided a workaround for the question, it helped me bump up the priority for adding support for continuous x axis scales. With the [DBIR](http:\/\/www.verizonenterprise.com\/DBIR\/) halfway behind me now, I kicked out a new rev of the package\/widget that has support for continuous scales.<\/p>\n

Using the data from the SO post, you can see there’s not much difference in how you use continuous vs date scales:<\/p>\n
