Two Variable Chart

 

Similar to the One Variable Time Chart except that a variable is also mapped to X. Time is now mapped to Z. This lens is good for comparing/contrasting variables – i.e. Assets & Liabilities. In the case of our sample data, we are comparing domestic product accounts (Y) to industry total requirements (X).  As with all other lenses, this lens works well with color and size mapped.

Working with the “Industries Only” space: 
see One Variable Chart

  3. Choose the attribute for the Y position (we chose “Gross Domestic Product by Industry Accounts”)
  4. Click Map
  5. Choose the attribute for the Z position (we chose Industry-by Commodity Total Requirements)
  6. Click Map
