當我繪製區域時,我開始困擾着我無法擺脫這個不斷出現的垂直線;Matlab垂直線在使用時持續出現和區域()
[x y] = ginputExtra(4)
x = 0.1947 0.6118 0.8329 0.4136
y = 0.5746 0.8173 0.4225 0.3553
area([x x(1)],[y y(1)])
[x y] = ginputExtra(4,true)
x = 0.5087 0.6881 0.4954 0.3204
y = 0.4961 0.2382 0.1566 0.3566
hold on;
area([x x(1)],[y y(1)],'FaceColor',[1 0 0])
有什麼辦法來避免這一行?
BTW:該ginputExtra方法調用我用..
function [x y] = ginputExtra(n,booText)
% INPUT
% n: Number of points to plot
% booText: Boolean (default false) command to display point number in
% the plot.

if nargin ==2
bText = booText;
else
bText = false;
end
H = gca;
set(H, 'YLimMode', 'manual'); set(H, 'XLimMode', 'manual');
set(H, 'YLim', get(H,'YLim')); set(H, 'XLim', get(H,'XLim'));
numPoints = n; xg = []; yg = [];
for i=1:numPoints
[xi yi] = ginput(1);
xg = [xg xi]; yg = [yg yi];
if i == 1
hold on;
plot(H, xg(i),yg(i),'ro');
if bText text(xg(i),yg(i),num2str(i),'FontSize',14); end
else
plot(xg([i-1:i]),yg([i-1:i]),'r');
if bText text(xg(i),yg(i),num2str(i),'FontSize',14); end
end
end
hold off;
x = xg; y = yg;
是想這一點,但不能使它在工作的時候。但現在它的工作就好了..奇怪..但是非常感謝你的幫助。 – Norfeldt 2012-04-12 12:16:47
沒問題!!!! – ThomasKJDK 2012-04-12 12:27:57
