QGIS "Categorized" Expression dialog , result show no "label/value" only "1"

Question

In ArcMap when I use Categorized I can choose what values I want to display using the "Add Values" button. In layer panel the values I chosen will show up there with the correct name.

I tried the same in Qgis, but the values doesnt show, I only get a number 1 and 0 but not the actual name in the column of the attribute-table.

Here is how I do: I got a layer with streets as polylines, each street has a streetname assigned to them in the attribute-table under the column "STREETNAME".

I go to "Properties->Style->Categorized".

Then I click the "Expression" button. In the "Expression Dialog" I create the following "expression".

"STREETNAME = 'ADAGE WY'

Here comes the problem, after I clicked "OK" and then "Classify" to classify based on the expression I dont get any values in the value column.

Is it supposed to work that way or am I doing something wrong? I was hoping that the streetname "ADAGE WY" would show as a "Value".

Answer 1

This result is correct, because you write expression "STREETNAME" = 'ADAGE WY' which gives you categories 1 (true) and 0 (false).

You can rename the legend value, or in Column left only "STREETNAME" and hit Add button and write value ADAGE WY
