I have two questions:
1. Is there a way to increase the line width of the axes? I have figured out how to do it
with the tick marks, but not the axes themselves.
2. When adding a label to plot (xlabel and ylabel) the label will be cropped if the font is
large. Is there a way to rescale the plot so that the size of the axis is adjusted to allow
for the larger font size? If not, how do I increase the buffer zone outside the plot?
