    Overlap Map points

    Kym Mercier


      I am trying to figure out how to overlay maps. I am attaching what I have so far. What I want is the following;

      1. A map of the bus lines in Colorado. I have this down easily. It shows the stops and the route the lines are taking

      2. Count of employees per zipcode.


      Problem I am having:

      I can get a count per zipcode based on stops. What I cannot get is the count per zipcode that are not long the transit lines! I need to show all employees all over the state no matter what if the people are along the transit lines.


      I really need the lines to show as they are and then the counts to show as bubbles (or shapes) or something.


      Please help!

          Hi Kym,


          Dots, lines and polygons are

          just (yet another) Mark Types.


          To have zipcodes on a (filled) map

          one needs the Marks for them --

          at least one for each zipcode.


          To draw the Marks one has to have

          a pair of (non-empty) Lat / Lon columns

          in the datasource (or as a row-level calc).


          Last but not least, one would like to draw

          those Marks on both panes of a Dual-Axis map,

          hence the modified Path Order calculation --

          with an added "path to nowhere" for the Null Route --

          covering all "orphan" zipcodes on the way.


          Please find the attached.

          Hope it helps.
