May I please ask you to help me?

When I copy an Excel chart and paste it into a Word document, all font sizes
change. On the original, the font of the labels on the y-axis is larger
than that for the x-axis, and yet once I paste the chart into Word, the font
of the labels on the x-axis is much larger than the font of the labels on the
y-axis.

I have objects in the title of my chart [Brownstone equation - "alpha
squared"]. In the orginal [excel chart] these objects are of the same size
as the letters in the chart title. However, once I paste the chart into
Word, these objects appear to be much larger than the rest of the chart
title.

Can this be fixed?

Thank you.
