Tô màu biểu đồ động

Question

Tôi đang cố gắng chứng minh kết quả từ luận án của mình thông qua việc sử dụng hình ảnh động. Tôi đã xây dựng một MWE cho những gì tôi đang cố gắng làm. Về cơ bản, tôi có một loạt các đỉnh, có màu tô được cung cấp bởi các giá trị RGB được lấy mẫu cho mọi thời điểm mà tôi đã ghi lại trong bảng CSV. Tôi muốn hiển thị sự phát triển màu sắc của các đỉnh đồ thị theo thời gian thông qua một hình ảnh động. Tuy nhiên tôi không thực sự chắc chắn về cách tốt nhất để thực hiện nó. Đó là lý do tại sao tôi muốn nghe ý kiến ​​/ đề xuất của bạn về chủ đề này. Đoạn mã sau tạo ra một đồ thị có ba đỉnh.

\documentclass{standalone}
\usepackage{tikz,calc}

\begin{document}
   \begin{tikzpicture}[align=center,node distance=5cm]
     \tikzset{
     vertex/.style={draw,circle, line width=3pt,minimum size=1cm,text width=1cm, align=center, font=\Large},
     arc/.style={draw, line width = 3pt,-}}
     % outer shell
     \node[vertex] (V1) at (0,0) {1};
     \node[vertex] (V2) [below right of = V1] {2};
     \node[vertex] (V3) [above of = V2] {3};

     % adjacency
     \draw[arc] (V1) -- (V2);
     \draw[arc] (V3) -- (V2);
     \draw[arc] (V3) -- (V1);
   \end{tikzpicture}
\end{document}

Hơn nữa, tôi có một bảng CSV bảng với các mục sau:

r1,g1,b1,r2,g2,b2,r3,g3,b3
0.8147,0.1576,0.6557,0.7060,0.4387,0.2760,0.7513,0.8407,0.3517

0.9649,0.9595,0.1712,0.0344,0.7547,0.2238,0.2575,0.4733,0.5678

r1, g1, b1 là các giá trị rgb của nút 1, v.v.

Cảm ơn bạn vì tất cả sự giúp đỡ!

Chỉnh sửa: Tôi muốn sử dụng tùy chọn tô màu RGB nếu có thể:

\node[...,fill={rgb:red,4;green,2;blue,1}]

Answer 1

Giải pháp này đọc các dòng có màu từ tệp bằng các hàm LaTeX3. Hơn nữa, nó sử dụng lệnh mới \multiframebreakđể thoát khỏi \multiframevòng lặp sớm. ( animate[ 2020/08/29])
