I am using PlotLegends in a Plot command to label each line of my plot (it has 4 different functions plotted) but the legend is split in two lines. I would like it two appear in a single line so it has the same appearance as the other plots displayed next to it. Is there a way to do that? I guess reducing the font size would be an option but I don't know how to do it.
I don't know if this is relevant, but afterwards I export the plot to an EPS file using the command
so maybe increasing the resolution might solve my problem.
I reduced the font size and still couldn't get it in one line. However, when I changed my legend labels from scientific notation (10^-2, using the -2 as a superscript) to fixed point notation (0.01) it worked (with the reduced font size). Here there is the final result so I managed to get it working. However, I would like, if possible, to understand what was the problem.
