and am not sure why. I'm trying to add formulas to a graph as fractions using this code:
text(10,.2,'Ea=$\displaystyle\frac{-1.436}{\r}$','interpreter','LaTeX')

This produces a result
text(.2,.2,'Ea=$\displaystyle\frac{-1.436}{17}$','interpreter','LaTeX')
With your example
  • Matlab seems to have trouble with "\r"?
  • "10" positions the text outside the default axes.

You were right on both counts. One: I had my x and y flipped. duh. the other i took out the backslash (don't know why) but this works: text(.3,-10,'Ea=$\displaystyle\frac{-1.436}{r}$','interpreter','LaTeX')
