Abordando el problema de manera diferente y predefiniendo el desplazamiento de cada línea (0,1,2,3) y luego cambiando el color de la línea en función de una variable , podemos llegar al resultado final.
Asumiendo como muestra, tenemos 4 líneas de igual tamaño.
Ejemplo probado:
A continuación se muestran las expresiones de color y el estilo general de QGIS que lograrán el resultado.
Esto funciona para mi prueba donde las variables se nombran como v1, v2, v3 y los valores de las variables son 26, 52, 78, 0 (divisiones iguales de 104).
Expresiones de color:
Offset 0 (línea superior):
--offset 0
CASE
WHEN "v2" = (104/4)*2 THEN '#ffe523'
ELSE '#277c3e'
END
Offset 1:
--offset 1
CASE
WHEN "v1" = (104/4)*2 THEN '#ffe523'
WHEN "v1" = (104/4)*1 THEN '#277c3e'
END
Offset 2:
--offset 2
CASE
WHEN "v1" = (104/4)*2 THEN '#f93131'
WHEN "v3" = (104/4)*3 THEN '#277c3e'
ELSE '#ffe523'
END
Offset 3 (línea inferior):
--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"
