    Tableau Data Export Options, Node Network View, & Absolute vs Relative Coloring and Sizing.

    .Michael Martin

      For your consideration:  (1)that Tableau Desktop (like Tableau Server) offer an export to .csv option (believe this was possible in earlier versions of Tableau), (2) if the user has "colored by", "sized by", or "shaped by" one or more measures on the canvas, that any export of the view include the scalar values Tableau assigned to those values for whatever portion of the view (subsequent filtering may have been applied) visible on the canvas.  This is valuable metadata that could be used to categorize / rank / cluster the data within a given destination environment.  This metadata could be represented using floating point numbers between -1 and 1 with a tanH function for sizing, and hex color codes for "color by" values, and mapping the standard shape types to one of a series of ordinal values. (3) a new "Network / Node View" wherein connections and relationships between aggregated or unaggregated data could be weighted and visualized.  One implimentation of this can be seen via the NodeXL Excel add-in (supports Excel 2007) at www.codeplex.com/NodeXL, and finally (4) the option to size and color relative to other values in a view (as currently) plus the option to use absolute sizing or coloring by the value of a measure.  There are times when after filtering larger or small measure values out of a view that you would still want to see the coloring and sizing originally applied by Tableau prior to filtering as opposed to Tableau re-sizing and re-coloring based on the data remaining in the view.  As the larger and / or smaller values are brought back into the view, the original coloring and sizing applied to those values would then return to the view.  Thanks for reading, Michael
