We recently had a user that was looking to distinguish polygons between each other using dashed lines, a style not currently available in the Report Map Tool. But that’s alright, we can use the opportunity to showcase how you can be creative in Alteryx by using a few tools.
In cifically filter out the record IDs you want to change or use the Sample tool to pull random records, or 1 of every N Records. (FYI – if you use the record ID, you will want to remove that column after you have split the records, due to the record ID used later in the mapping process.)
Once you have selected the polygons you want to use, you will need to break those polygons into individual points using the Poly-Split tool. Here, choose Polygon field and Split to Points. Splitting the polygon into points will allow you to adjust the polygon by each point.
Then, you'll want to remove some of the points to create the “dotted line” effect by using the Sample tool. This tool's settings will want 1 of every N Record selected (you can change the N=3 to any number you like that will have the spacing effect you want).
Now that you have removed some points, you'll want to do a few things to give the points a grouping effect. In order to do this, add another Record ID tool, then filter the record ID by odd and even numbers. You can do this using the Filter tool and using the expression mod([Record ID],2)>0. Then add Record ID tools to the T and F anchors to complete the grouping effect when you add them both to a Union tool.
Grouping the points allows you to build your Polylines. After the Union tool, add a Poly-Build tool. The Build method will be Sequence Polyline using the SpatialObj and the RecordID, as the Source and Group fields, respectively.
Your final step is to add a Map tool and pull in the data from your Poly-Build tool, as well as the original centroid points of the polygons with which you created the split lines, and finally the remaining polygons you want to be represented as full lines around the radius. When configuring the Map tool, remember that the points coming from the Poly-Build are actually lines and not Polygons. Your layering will need to have Points, Lines, and Polygons to complete the map.
