Column vs. row vector

[1oly]

Hi there,
It seems that I get an empty plot when I try to plot row vectors. Do others see this behavior or is it maybe on purpose?

: Produce correct plot:
x = [1.0:10.0];
y = x.*x;
plot(x,y)

: Produce empty plot:
x = [1.0:10.0]';
y = x.*x;
plot(x,y)

Matplotlib treats each column of the data as a separate data series. So, if you give it row vectors, it is treated as a set of single-point datasets. For example, compare the output of

plot([1,2,3], [1,4,9], "o-")

with

plot([1,2,3]', [1,4,9]', "o-")

Thanks Steven!
