Help for PlotLegend font size

Questions

Hello all,

I attach a notebook.

The numbers on the axis are too small and the mu_Y in the legend also.
Can someone help me solve this.

Kind regards.

Use Style for axis labels to choose font size, for example

AxesLabel -> {Style[x, 24], Style[y, 24]}

Hello,
Can we change the size from the PlotLegends only (without the AxesLabel)?
Thanks.

PlotLabel → Style[“xxxx”, 24]

Dear Mr. S M Blinder,
Thanks for your reply but my intention is to change the LegendSize only not the size of the PlotLabel, FrameLabel or Ticks. I can’t find any information to change the LegendSize only. Thanks.
