具有多个标记的散点图 [英] Scatter plot with multiple markers

问题描述

我正在尝试将多个数据文件中的散点图放在一起，以查看它们之间的相互关系.代码如下:

I am trying to put a scatter plot together from multiple data files, to see how the correlate to each other. The code looks like this:

hold all
fia = fopen('data.txt');
A = fscanf(fia, '%f %f %f', [3 inf]);
t = A(1,:);
a = A(2,:);
r = A(3,:);

figure(1)
scatter(log(r),log(a),'r', '-');

fclose(fia);

fia = fopen('data.txt');
A = fscanf(fia, '%f %f %f', [3 inf]);
t = A(1,:);
a = A(2,:);
r = A(3,:);

figure(2);
scatter(log(r),log(a), 'g', '-');

fclose(fia);

依此类推，下一个数据点绘制在同一图形上:

And so on, where the next data points are plotted on the same graph:

fia = fopen('data.txt');
A = fscanf(fia, '%f %f %f', [3 inf]);
t = A(1,:);
a = A(2,:);
r = A(3,:);

figure(1);
scatter(log(r),log(a), 'rx');


fclose(fia);

ect.

但是当我在Matlab中运行该函数时，出现此错误:

But when I run the function in Matlab, I get this error:

Error using specgraph.scattergroup/set
The name 'linestyle' is not an accessible property for an instance
of class 'scattergroup'.

Error in specgraph.scattergroup (line 26)
  set(h,args{:});

Error in scatter (line 83)
        h = specgraph.scattergroup('parent',parax,'cdata',c,...

Error in Ratioincrease (line 11)
scatter(log(r),log(a),'r', '-');

如何使散点组类似于线路组，如我如何正确地编写它?

How can I have the scattergroup similar to a line group, as in how do I write it properly?

推荐答案

使用scatter并显示不同的标记应该没有问题.例如:

There shouldn't be a problem to use scatter and show different markers. For example:

load seamount
scatter(x,y,30,z,'s'); hold on
scatter(.999*x,1.001*y,30,z,'x'); hold on
scatter(1.001*x,.999*y,30,z,'+'); hold on

我怀疑您输入错误，并使用-作为标记类型.您可以使用的标记类型为:

I suspect that you had a typo and used - as a marker type. The marker types you can use are :

• '+'加号
• 'o'圈子
• '*'星号
• '.'点
• 'x'十字架
• 'square'或's'正方形
• 'diamond'或'd'钻石
• '^'朝上三角形
• 'v'指向下的三角形
• '>'右指向三角形
• '<'左指向三角形
• 'pentagram'或'p'五角星(五角星)
• 'hexagram'或'h'六角星(六边形)

• '+' Plus sign
• 'o' Circle
• '*' Asterisk
• '.' Point
• 'x' Cross
• 'square' or 's' Square
• 'diamond' or 'd' Diamond
• '^' Upward-pointing triangle
• 'v' Downward-pointing triangle
• '>' Right-pointing triangle
• '<' Left-pointing triangle
• 'pentagram' or 'p' Five-pointed star (pentagram)
• 'hexagram' or 'h' Six-pointed star (hexagram)
