Create a Polyline map
Custom lines can be drawn on a map using any number of points that are connected by a line. These can be used to draw lines that follow utility lines or roads but can also be used to customize multi-leg spider charts.
The examples below make use of a string of Lat / Long points. However, as of QM 2.6.1, polyline encoded format is supported as well. For more information on creating polyline encoded formated shapes, see here.
If you are using a polyline encoded format, you must add the following to the Feature Options box.
'
"isLine":"true"
'Create a Polygons / Lines map
Add a 'Dimension' to the Polygon / Lines properties box of the QlikMaps Polygon / Lines object.
In the 'Boundary / Path' expression box format a string enclosed in single quotes in the following format:
'LINESTRING( <Start Longitude> <Start Latitude> , <Next Point Start Longitude> <Next Point End Latitude> )'There can be as many points as necessary to create a line as long as each set of <Longitude Latitude> points are separated by a comma.
Below is a very simple example consisting of 4 points.
Configuring Polylines
Colors
By default, Polyline colors are randomized. The color can be changed using an expression in the Fill Color Expression box.
=red()or
=if( sum( aggr( Receipts, SalesmanName)) > 2000000, Green(), Red())
Feature Options
By default, Polylines are solid. Additional modifications can be made to the line.
='
"opacity":"80",
"weight":"5",
"linecap":"butt",
"dashArray":"3,3",
"curved":"false",
"featurePinType":"arrow",
"featurePinLocation":"random"
'This will format every line accordingly. An expression can be used to modify each line differently depending on the row it is a part of.
