The most straightforward solution is using the offset option in the set ylabel command. Basic Offset Syntax The offset takes three parameters: horizontal, vertical, and depth (for 3D plots): set ylabel “Y Label” offset <x_offset>,<y_offset>,<z_offset> Positive values…

You can control font sizes at multiple levels: globally for the terminal, for axis labels and tick marks, for legends, and for individual text elements. Global Terminal Font Size Set a default font and size for your entire…
