I want to plot a graph with a dashed and a solid line. Therefore, I use the script "subplot(221); spm1d.plot.plot_meanSD(Y0, 'color','k','--'); hold on ; spm1d.plot.plot_meanSD(Y1, 'color','r','-');"

However, I always get the following error: "Error using spm1d.plot.plot_meanSD (line 12) '--' is not a recognized parameter".

How can I plot it correctly?

or to more closely align with original attempts

plot(x,y,'Color','k','LineStyle','--')

so "LineStyle" is the parameter you want to have the value "--"

You need to precede the linestyle you want with the keyword 'LineStyle'

plot(x,y,'Color','k','LineStyle','--')

so "LineStyle" is the parameter you want to have the value "--"

Darova's answer is the typical shorthand for combining linestyle and color into a single key-less option, which has to be the 3rd argument (or 2nd, if there's not 1st argument, I think).
