Error using plot; invalid first data argument
显示 更早的评论
%this is my code. it is returning the titular error and I cannot figure out why
data=load('riverspeed.html')
x=data(1,:)
y=data(2,:)
color=input('select color')
symbol=menu('Select symbol','point','circle')
switch symbol
case 1
plot(x,y,color,'.')
case 2
plot(x,y,color, 'o')
end
%'riverspeed.html' is a random two row matrix

switch symbol
case 1
plot(x,y,strcat(color,'.'))

Then please explain the type and contents of this first argument.
data = load('riverspeed.html');
x = data(1,:);
class(x)
size(x)
x
What do you get? I guess load('*.html') does not do, what you expect, because load is not designed for HTML files.
