Matlab, Plot/Graph Changes when the Line Style Changes

Question

I am using Matlab ver R2017A. When I plot the following code below, I get a sine wave as expected using the default line style.

x = linspace(0,10);
h1 = sin(x);
plot([x,h1],'--')
legend('Location','southwest')

However, when I add a different line style, the plot goes all wonky. From a sine wave, it changes to some half triangular wave followed by very small sine waves, with of course using a dashed line style.

x = linspace(0,10);
h1 = sin(x);
plot([x,h1],'--')
legend('Location','southwest')

I then tried the following, but now the plot/graph completely disappeared from the figure. All I see are the X and Y axes:

plot(x,h1,"LineStyle",'--');

Any ideas why this is happening and how to correct it?

Answer 1

Oh forget it. I fixed the issue. I needed to remove the square brackets. I assumed the R2022 syntax was the same as documented in R2017A. By default, a search on google will bring you to the latest version of the documentation. I decided to search R2017A and there it was; no square brackets. The latest Matlab documentation would normally mention changes to the syntax from previous version, but in this case it did not.
