如何传递一系列线规格或样式进行绘制? [英] How do I pass an array of line specifications or styles to plot?

问题描述

我想一次调用plot()绘制多条线，每条线具有不同的线型.这是一个示例:

I want to plot multiple lines with one call to plot(), with different line styles for each line. Here's an example:

两者

plot([1,2,3]', [4,5;6,7;8,9], {'-o', '-x'})

和

hs = plot([1,2,3]', [4,5;6,7;8,9])
set(hs, 'LineStyle', {'--'; '-'})

不起作用.我已经尝试了一大堆带有方括号和花括号的奥术组合，但似乎无济于事.

don't work. I've tried a whole bunch of arcane combinations with square and curly braces, but nothing seems to do the trick.

我知道可以遍历Y列并为每个列调用plot()(例如

I know it's possible to loop through the columns in Y and call plot() for each one (like in this question), but that isn't what I'm after. I would really like to avoid using a loop here if possible.

谢谢.

PS:我找到了这个'prettyPlot'脚本，说它可以做这样的事情，但我想知道是否有任何内置的方法.

PS: I found this 'prettyPlot' script which says it can do something like this, but I want to know if there's any built-in way of doing this.

PPS:对于任何想要快速解决此问题的人，请尝试以下方法:

PPS: For anyone who wants a quick solution to this, try this:

for i = 1:length(hs)
   set(hs(i), 'Marker', markers{i}); 
   set(hs(i), 'LineStyle', linestyles{i}); 
end

例如与markers = {'+','o','*','.','x','s','d','^','v','>','<','p','h'}

推荐答案

引用 http://www.mathworks.com/help/matlab/ref/plot.html ，这是如何使用一个绘图命令绘制多条线的方法:

Referring to http://www.mathworks.com/help/matlab/ref/plot.html, this is how to draw multiple lines with a single plot command:

plot(X1,Y1,LineSpec1,...,Xn,Yn,LineSpecn)

所以您对

plot([1,2,3]', [4,5;6,7;8,9], {'-o', '-x'})

必须写为:

plot([1,2,3]', [4,6,8], '-o', [1,2,3]',[5,7,9],'-x')

结果:

将输入参数重新组织到单元格数组中，并使用cellfun将plot命令应用于每个单元格元素.

Reorganize input parameters into cell arrays and use cellfun to apply plot command to each cell element.

x = [1,2,3]';
xdata = {x;x};
ydata = {[4,6,8];[5,7,9]};    
lspec = {'-o';'-x'};

hold all;
cellfun(@plot,xdata,ydata,lspec);
