VC# + GDI+ 绘制

Matlab，使用graph的plot，可以设定点的位置，相对简单些
clc; clear;s = [1 1 1 1 1 1 1 9 9 9 9 9 9 9];t = [2 3 4 5 6 7 8 2 3 4 5 6 7 8];G = graph(s,t);h = plot(G)h.XData = [0 -3 -2 -1 0 1 2 3 0];h.YData = [2 0 0 0 0 0 0 0 -2];
调整节点位置，利用pause制作动画
clc; clear;s = [1 1 2 4 5 6 1 2 3];t = [2 3 3 7 8 9 4 5 6];G = graph(s,t);h = plot(G)h.XData = [0 -1 1 -1 0 1 -1 0 1];h.YData = [2 1 1 -1 -1 -1 -2 -2 -2];h.LineWidth = 3;h.MarkerSize = 8;pause(0.2)s = [1 1 2 4 5 6 1 2 3];t = [2 3 3 7 8 9 5 4 6];G = graph(s,t);h = plot(G)h.XData = [0 -1 1 -1 0 1 -1 0 1];h.YData = [2 1 1 -1 -1 -1 -2 -2 -2];h.LineWidth = 3;h.MarkerSize = 8;pause(0.5)s = [1 1 2 4 5 6 1 2 3];t = [2 3 3 7 8 9 6 5 4];G = graph(s,t);h = plot(G)h.XData = [0 -1 1 -1 0 1 -1 0 1];h.YData = [2 1 1 -1 -1 -1 -2 -2 -2];h.LineWidth = 3;h.MarkerSize = 8;
这儿有一个如何利用matlab制作gif图的教程。
这个博客的方法好，提供了一个库函数
function savegif(varargin)global iiii;global time;tip=0;p=clock;if isempty(varargin) filename='untitledgif.gif';else filename=varargin{ 1}; if length(filename)<4 filename=[filename,'.gif']; else if ~strcmp(filename(end-3:end),'.gif') filename=[filename,'.gif']; end end if nargin>=2 tip=1; end endif isempty(iiii) iiii=0; time=p(6);else iiii=iiii+1; if ((p(6)>=time)*(p(6)-time)+(p(6) 100 iiii=0; end time=p(6);endif tip ==0 f=getframe(gca);%getframe(F)gets a frame from the current axes else pos=get(gcf,'position'); f=getframe(gcf,[1,1,pos(3),pos(4)]);endf=frame2im(f);[f,map]=rgb2ind(f,256);if iiii==0 || exist(filename,'file')==0 imwrite(f,map,filename,... 'delaytime',rand(1));else imwrite(f,map,filename,'writemode','append',... 'delaytime',rand(1));end 绘制代码，做了5个拓扑快照
