Sử dụng công thức để đặt độ lệch của mẫu đường trên QGIS 2.18

8

Tôi đã cố gắng lấp đầy các đa giác ranh giới thành phố bằng mẫu sọc 3 màu (đỏ, cam, xanh lục), có độ dày tương ứng tỷ lệ với 3 biến, khác nhau cho mỗi thành phố, nhưng tổng của nó luôn là 104 (ví dụ như hình) .

Ví dụ sọc

Tôi đặt một mẫu đường có 3 dòng, đỏ, cam và xanh lục. Sửa khoảng cách thành 4mm và sử dụng biểu thức máy tính trường, tôi đã thành công trong việc làm cho chiều rộng của mỗi màu khác nhau:

Variable_1/104*4    #for red
Variable_2/104*4    #for orange
Variable_3/104*4    #for green

Nhưng các biểu thức để đặt bù không tạo ra bất kỳ thay đổi bù nào:

Variable_1/104*2                                            #for red
Variable_1/104*4 + Variable_2/104*2                         #for orange 
Variable_1/104*4 + Variable_2/104*4 + Variable_3/104*2      #for green

Áp dụng sọc

Có điều gì đó tôi đã không đặt chính xác?

Tôi đã cố gắng sao chép và đang gặp vấn đề tương tự (QGIS 2.14). Biểu thức bù dường như bị bỏ qua. Một đề xuất là lưu kiểu của bạn dưới dạng tệp .qml và sau đó điều tra việc này. Một khả năng khác là tìm cách kiểm soát thứ tự vẽ của các đường (để đường dày nhất được vẽ trước, với các đường khác được vẽ ở trên), điều này sẽ đạt được kết quả cuối cùng.

Câu trả lời:

Tiếp cận vấn đề khác nhau và xác định trước mỗi dòng bù (0,1,2,3) và sau đó thay đổi màu đường dựa trên một biến sau đó chúng ta có thể đi đến kết quả cuối cùng.

Giả sử như bạn hiển thị, chúng tôi có 4 dòng có kích thước bằng nhau.

Ví dụ thử nghiệm:

Ví dụ làm việc

Dưới đây là các biểu thức màu sắc và phong cách tổng thể của QGIS sẽ đạt được kết quả.

Điều này hoạt động cho thử nghiệm của tôi trong đó Biến được đặt tên là v1, v2, v3 và các giá trị biến là 26, 52, 78, 0 (các phân chia bằng nhau của 104).

Biểu hiện màu sắc:

Offset 0 (dòng trên cùng):

--offset 0
CASE 
    WHEN "v2" = (104/4)*2 THEN  '#ffe523'
    ELSE  '#277c3e' 
END

Bù đắp 1:

--offset 1
CASE 
    WHEN "v1" = (104/4)*2 THEN  '#ffe523'
    WHEN "v1" = (104/4)*1 THEN  '#277c3e' 
END

Bù đắp 2:

--offset 2
CASE 
    WHEN "v1" = (104/4)*2 THEN  '#f93131'
    WHEN "v3" = (104/4)*3 THEN  '#277c3e' 
    ELSE '#ffe523'
END

Offset 3 (dòng dưới cùng):

--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"
field.
An example follows:
"""
from PyQt4.QtGui import QWidget

def my_form_open(dialog, layer, feature):
    geom = feature.geometry()
    control = dialog.findChild(QWidget, "MyLineEdit")
