[咨询求助]怎样才能用MATLAB绘制纵轴向下的图 [复制链接]

如题，正常的坐标系作图没有问题，但是我想看一下井曲线，或者看地震剖面，要求纵轴（时间轴）向下，应该怎么用MATLAB实现呢？
请高手解答一下！
谢谢！

应该要做一个坐标变换吧!

命令语句：set(h,'XDir','reverse')
修改XDir = reverse，建议系统学习MATLAB句柄图形系统，了解每种控件的常用属性，如果要用MATLAB做GUI程序的话。

不知道是不是这个效果，，你试试！我试过了，

clear;clc
load D:\Nanyang\B7.txt  %加载你的测井曲线
x=B7(:,2);%B7的第二列是R25曲线
y=0:length(x)-1;%画图时x,y必须大小相同
%假如你的测井曲线的时间最大为2s
m=max(y)/2；
t=y/m；
plot(x,t)

function flipy
% FLIPY: script to flip the direction of the y axis
%
% just type "flipy" at the matlab prompt
state=get(gca,'ydir');
if(strcmp(state,'normal'))
    set(gca,'ydir','reverse')
else
    set(gca,'ydir','normal')
end

flipy  %将时间从0-2显示

至于看地震剖面，这个比较复杂些，我有个显示地震剖面的包，里面的函数plotimage(seis,x,t)就可以直接显示你的地震数据，是变密度显示的，你也可以用wiggle显示。需要的话可以传给你，qq:27567666

多道地震记录，用patch命令可以实现，时间轴是向下的，用句柄命令SET
