別の方法で問題に取り組み、各線のオフセット(0、1、2、3)を事前に定義し、変数に基づいて線の色を変更すると、最終結果を得ることができます。
あなたが示すように、私たちは4つの同じサイズの線を持っています。
テストされた例:
以下は、結果を実現する色の表現と全体的なQGISスタイルです。
変数は次のように命名されている私のテストのためにこの作品V1、V2、V3および変数値は、26、52、78、0(104の等しい分割)。
色表現:
オフセット0(上部の線):
--offset 0
CASE
WHEN "v2" = (104/4)*2 THEN '#ffe523'
ELSE '#277c3e'
END
オフセット1:
--offset 1
CASE
WHEN "v1" = (104/4)*2 THEN '#ffe523'
WHEN "v1" = (104/4)*1 THEN '#277c3e'
END
オフセット2:
--offset 2
CASE
WHEN "v1" = (104/4)*2 THEN '#f93131'
WHEN "v3" = (104/4)*3 THEN '#277c3e'
ELSE '#ffe523'
END
オフセット3(最終行):
--Offset 3 always red
'#f93131'

QGIS forms can have a Python function that is called when the form is
opened.
Use this function to add extra logic to your forms.
Enter the name of the function in the "Python Init function"

An example follows:
