This question centers the Symbology tab in QGIS 3.0.
I'm working with categorical data describing event venues in the Chicago area. This is a point dataset which will be overlayed on a street basemap.
I would like to use the Symbology tool in the Properties window to display "Bars" specifically in red, and "all other values" (nightclubs, theaters, other, etc.) in yellow.
The attribute field I am using is called "Type"
Fundamentally, I have solved this problem using the following process:
- Column Drop Menu -> Select "Categorized"
- "Formula" button
- "Type" = 'Bars' (syntax)
- Select "Classify" button
- Outcome: classifcation of "0" represented in Yellow, and "1" in Red. "1" = "Bars", "0" = "all other values/anything that is not a bar"
- Change Legend entry for "1" value to read "Bars"
- Change Legend entry for "0" value to read "All Other Venues"
Indeed, this process solves the problem of isolating the desired value and representing all other values.
I would however like to clarify... is this the only way to isolate one value and represent all others? Many of the folks I work with are coming from the ArcMap 9 and 10 environments, which make this process super easy using selectable options in the GUI rather than formulas.
Have I missed a GUI method of completing this task while solving this problem or should I start working with formulas?
