hey people
i have an problem on plotting some functions with latex texts. i cant
plot some latex symbols like \bar or something else.... the normal latex
stuff works perect, but such keys doessent and i dont know why...
hope someone can help me
as you can see i attached a sample plot file... you find the latex
problem in line pl.ylabel() ... the \bar doessent work
here is the error message i got
