these cosmetic changes can be important characteristics of visualization, handling.

for example

1: [Save] field overlaps
2: The name of the second graphic does not appear.
3: frame work, the flag seems to be inverted
4: ticks must have at least one space, because it gives the appearance of negative numbers -80 -> - 80
also place a space before the units
gl_x_axis_unit="x_u", gl_y_axis_unit="y_u";
0y_u -> 0 y_u
I think the units label should only go on the axes
